Hello 👋 I'm Janar, and I have over 9 years of experience in data analytics, growth marketing and engineering. I'm passionate about helping businesses make better decisions through accurate tracking and meaningful data insights. Over the past decade, I've worked with several companies in SaaS, iGaming, and crypto industries to build reliable tracking systems and create actionable reporting dashboards. My technical skills in data engineering and experience in marketing allows me to handle both the implementation side and the advanced analysis that follows. My day-to-day work covers a wide range of projects: 𝐓𝐞𝐜𝐡𝐧𝐢𝐜𝐚𝐥 𝐬𝐞𝐭𝐮𝐩𝐬: - Tracking setups for GA4, PostHog, Amplitude and Mixpanel - Server-side tracking using Stape, GCP or Google Gateway with GTM - Google Tag Manager configuration and server-side tracking with Stape, GCP or Gateway - Conversion tracking for Google Ads, Meta, LinkedIn, and other platforms - CRM tracking and lead source attribution - Consent compliance and privacy-safe data collection 𝐀𝐝𝐯𝐚𝐧𝐜𝐞𝐝 𝐚𝐧𝐚𝐥𝐲𝐭𝐢𝐜𝐬: - Data warehouse architecture with GCP and BigQuery - BigQuery data analysis and custom reporting - Attribution modeling and cross-channel analysis - API integrations and data pipeline development - Metrics analysis (CLV, MRR, Churn, CAC, ROAS, FTDs..) 𝐃𝐚𝐭𝐚 𝐕𝐢𝐬𝐮𝐚𝐥𝐢𝐳𝐚𝐭𝐢𝐨𝐧 & 𝐁𝐈: - Looker Studio dashboard development - Executive reporting and KPI monitoring systems - Automated reporting workflows and alerts Whether you need a complete analytics setup, server-side tracking implementation, custom BigQuery reporting, or Looker Studio dashboards, I can help you build a data-driven foundation. Ready to get your analytics working the way it should?

I build full-stack SaaS products end to end. Frontend in React/Next.js or Vue/Nuxt, backend in Node with tRPC/REST, Postgres with Prisma, deployed and monitored with Sentry and Posthog in production. Recent proof. I built and shipped my own AI product solo, Phosphene, an AI image generation workspace. Auth, Paddle billing, generation pipelines, graph-based editor, Postgres, deployment on Hetzner. Live at phosphene.cc. Before that I spent 5 years on a B2B energy-brokerage platform (acquired by AppDirect), where I shipped data-heavy dashboards, an AI bill-scanning feature on Gemini, and grew test coverage from 0 to 80% with Vitest and Cypress. 41 Upwork jobs, 8,500+ hours, Top Rated Plus. I work fast, communicate clearly in async, and ship production quality, not prototypes. Good fit if you need a SaaS dashboard or admin tool, an AI feature integrated into your product, a Figma design turned into a working app, or a messy codebase modernized.

I help startups and enterprises build production software that scales. With 20+ years of engineering experience, I deliver end-to-end solutions across AI, mobile, backend, cloud, and automation, from architecture and implementation to deployment and long-term support. I also build analytics, marketing automation, and data platforms, helping businesses measure user behavior, optimize conversions, and automate operations using modern analytics and AI tooling. 🏆 Selected Highlights ✅ Production mobile apps with millions of downloads across iOS & Android ✅ AI-powered platforms serving Amazon Prime, Disney+, Discovery & Universal ✅ Clinical SaaS platform acquired for $53M ✅ Enterprise data systems supporting 3,143 US counties ✅ Production SDKs contributing to $5.7M in licensing deals ✅ Delivered $3.1M in annual operational savings with 377% productivity improvement 💡 Core Expertise 🤖 AI & LLM • Claude • OpenAI • MCP • RAG • AI Agents • LangGraph • Vector Search • Prompt Engineering ⚙️ Backend • Python • FastAPI • Node.js • TypeScript • PostgreSQL • REST • GraphQL • Microservices 📱 Mobile • React Native • Flutter • Swift • Kotlin • Expo • BLE • Firebase • App Store & Google Play ☁️ Cloud & DevOps • AWS • Azure • GCP • Docker • Kubernetes • Terraform • GitHub Actions • CI/CD 📊 Analytics & Data • Google Analytics 4 (GA4) • Google Tag Manager (GTM) • Looker Studio • Google Search Console • PostHog • Mixpanel • BigQuery • Snowflake • A/B Testing • Event Instrumentation • Conversion Tracking • Product Analytics 📈 Marketing & Growth • HubSpot • Shopify • Stripe • Meta Marketing API • Facebook Conversions API (CAPI) • Google Ads • Klaviyo • CRM Automation • Email Marketing • Lead Tracking 🔗 Automation & Integrations • n8n • Make • Zapier • Twilio • Microsoft Graph API • Shopify APIs • Google APIs • Slack API • Webhooks 🔒 Security & Compliance • SOC 2 • ISO 27001 • HIPAA • SOX • GDPR-Aware Architecture • OAuth • JWT • RBAC 🎯 What You Can Expect ✔️ Production-ready architecture ✔️ Clean, maintainable code ✔️ Fast delivery using Claude Code & Cursor ✔️ Proactive communication ✔️ Scalable, secure, and reliable solutions ✔️ Long-term technical partnership 🌟 Available For • Fractional CTO • AI & LLM Systems • Full-Stack Development • Mobile Applications • Cloud Architecture • API Development • Automation & Integrations • Technical Leadership

I'm a Top Rated freelancer specializing in production level systems across SaaS, B2B platforms, AI integrations and automation heavy applications. I build production systems that don't break under real usage and hold up under real users, real data and real business pressure. My work sits at the intersection of Full-Stack engineering, AI systems, CMS platforms and business critical integrations. I focus on building applications that are stable, scalable and actually usable in real world environments. * On the frontend I build modern web applications using #React and #Next.js with #Typescript, #Tailwind CSS and scalable component based architecture. I focus on #clean UI, #responsive layouts, #performance optimization, #accessibility and smooth user experience across desktop and mobile. I also work with #dashboard systems, #SaaS platforms, #real interfaces, #authentication flows and complex frontend state management. *On the backend I design and develop scalable systems using #Node.js, #Python and #Go with #PostgreSQL, #Supabase, #MongoDB and #REST/GraphQL APIS. My work includes #authentication systesm, role based access control, #payment integrations, #automation workflows, #file handling, #API architecture, #database design and #cloud deployment. I focus heavily on maintainability, security, performance and building backend infrastructure that can scale without becoming difficult to manage later. * On the CMS side I work extensively with #Shopify and #WordPress including #custom theme development, #storefront customization, #Shopify Liquid, #App integrations, #WooCommerce, #Elementor, #Divi, #WPBakery and #performance optimization. I also handle #CMS migrations, #responsive redesigns, #SEO friendly structures and ongoing maintenance for production websites and eCommerce stores. * On the Automation & B2B system side I build workflow automation and integration systems that connect business tooles into unified processes. # API integrations(thrid party SaaS systems, CRMs, internal tools) # Workflow automation pipelines # Data synchronization systems # Event based automation # Scheduled jobs # Webhook orchestration # ETL-style data flows # Reporting automation and system to system communication design I specialize in reducing manual business operations by turning them into automated, reliable backend workflows. Where I bring extra value is in AI and system design. I don't just plug in APIs. I design AI features that fit into the product. # LLM integrations & LLM based workflow design for real workflows # Retrieval augemented systems and internal knowledge tools # AI driven reporting and automation pipelines # Structured, predictable outputs for business use # OpenAI API integration # Prompt-to-structured-output systems # RAG & vector database concepts I also work with SAP integrations and B2B data flows, connecting external systems, APIs and enterprise tools into a clean, reliable arhcitecture. This includes handling structured data, automations and backend logic that supports business operations. My QA background shapres everything I build. I'm ISTQB certified and experienced in both manual and automation testing using Java and Python, along with tools like Locust and Gatling for performance and load testing. *** I validate how they behave in real world conditions. This means after delivery, deployment, systems are tested with a quality focused mindset. I focus on edge cases, performance issues, API reliability and user flow stability are all considered before delivery. *** If you're building something that needs to be reliable, scalable and actually used by customers or internal teams, I can help you get it there. Regards, Oleksandr.

Most automation contractors build a workflow and move on. If you need someone who treats your production systems with the same care as your own team would — documenting before touching, staging before deploying, communicating before changing anything — that's how I work. What I build: ✅ End-to-End Workflow Automation Custom Make .com and n8n scenarios from scratch or on top of existing systems. Complex multi-step logic, error handling, scheduling, and data mapping — built to run without babysitting. ✅ CRM & Business System Integrations HubSpot, GoHighLevel, Salesforce connected to the rest of your stack. I've built sync engines that eliminated manual data entry across 4 platforms and gave teams a single source of truth. ✅ API & GraphQL Integrations If two tools need to talk and there's no native connector, I build the bridge — webhooks, custom API modules, GraphQL queries and mutations. ✅ AI Workflow Automation LLM integrations using OpenAI and LangChain: lead qualification agents, document processing, behavior-based outreach, voice analytics. Built a sales call grading system that cut manual QA time by 80%. ✅ Data Pipelines & Reporting ETL pipelines processing thousands of records daily, surfaced in Looker Studio, Metabase, or Airtable — so decisions get made on clean data. 5 years. Production systems. Clear communication. If your current automation is fragile, half-built, or just needs a reliable person to own it — send me a message and describe what's broken.

AI app developer — I build AI image, video, and voice apps for iOS and Android (ChatGPT, OpenAI, Gemini, fal.ai), with the unit economics designed in from day one. Every feature in an AI app has a price tag — each image, video, or transcription is an API call you pay for — so I build apps where users pay for credits before your backend spends a cent on AI. Every API call is profitable instead of a cost you eat. This isn't theory — it's how my shipped apps work: - An AI image / video / music generator app (fal.ai, Gemini, ElevenLabs) — built solo and shipped in under a month on iOS and Android, with an atomic Firestore credit ledger, RevenueCat subscriptions + coin packs, and moderation gates so policy-violating requests still consume the credit. - An AI celebrity image / video iOS app (Swift / SwiftUI, fal.ai + Gemini) — I own all post-handoff development: five shipped App Store releases, the credit/quota architecture, paywall, and Cloud Functions backend. - An AI voice-notes app (OpenAI Whisper + GPT, Google AI) — primary author (~80% of the code), with a credit + in-app purchase system. WHAT I BUILD INTO YOUR APP - Monetization that protects your margin: in-app purchases via RevenueCat, StoreKit, and Google Play Billing — subscriptions with fixed daily credits (non-rollover), one-time credit packs, token quotas with hourly/daily/weekly resets, and paywalls that appear exactly when the balance runs out. - Web credit top-ups via Stripe: a companion web app where users buy credits outside the app stores and spend them in your mobile app — lower fees, structured to stay store-compliant. - AI integration done right: ChatGPT / OpenAI, Google Gemini, fal.ai, ElevenLabs, and whatever frontier model fits your product — with queue + webhook patterns so long-running jobs survive app restarts, and NSFW / content-moderation gates built in. - Identity & analytics: Google and Apple SSO, email/password, and phone OTP, so every credit and event ties to a real user. PostHog instrumented across the funnel (install → signup → paywall → purchase → generation). Account deletion built in for store compliance. - Store launch as a fixed milestone: I handle App Store and Play Store submission and review — the milestone is paid when your apps are live, not when I press "submit." STACK & TRACK RECORD Flutter / Dart (my primary stack for 5+ years; 7+ years in mobile), Firebase (Auth, Firestore, Storage, Cloud Functions v2 in TypeScript), and native Kotlin / Swift for the gaps Flutter can't reach — watchOS / Wear OS companion apps, platform channels, VoIP push. When Firebase isn't enough, I build the backend myself: Node / Express / PostgreSQL with Stripe hold-and-capture payments. Payment systems integrated across projects: RevenueCat, Stripe, SumUp, Mollie, Flutterwave. ~380,000 hand-written lines of code across 40+ solo projects, 11 shipped. Currently also contributing to GETTR, a public social app with a ~494k-line Flutter codebase — performance optimization, live-streaming features, and test automation. If your AI app is bleeding API costs — or you want the next one built profitable from day one — send me a message with what you're building. I'll come back with a concrete plan: credit model, paywall placement, analytics events, and a fixed launch milestone.

🏆 Top 1% Fractional CMO/CRO operating at board and C-suite altitude. ARR Impact $500M to $1.8B | 3,000+ Campaigns | $15M+/mo Ad Spend 🌎 MBA and Executive Master in Finance. 15+ years of global revenue leadership across PE/VC-backed and growth-stage companies. 🌟🌟🌟🌟🌟 “Roger operates at a true CMO/CRO level. Clear thinking, fast diagnosis, and immediate revenue clarity. He rebuilt our GTM strategy and RevOps in weeks, not months.” 🌟🌟🌟🌟🌟 “Sharp. Senior. Strategic. Roger is the kind of partner founders and CEOs rarely find. He brought structure, focus, and commercial rigor that shifted our entire revenue trajectory.” 🚨 THE STRATEGIC INSIGHT Most mid-market and PE/VC-backed organizations suffer from an infrastructure and alignment lag. Campaigns are active, leads are flowing, yet the pipeline remains flat. The breakdown is rarely a top-of-funnel volume problem. The failure points are systemic: • The Valuation Gap: Structural misalignment between marketing’s lead definition and sales’ bottom-line conversion reality. • Static Data Architectures: CRMs logging historic activity rather than providing forward-looking, real-time financial insights. • The AI Execution Trap: Open-ended AI pilots delivering disconnected, vanity-metric tasks rather than automated, end-to-end commercial outcomes. ⚡ I operate at the 𝗥𝗲𝘃𝗲𝗻𝘂𝗲 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 level. I unify demand generation, sales velocity, and customer retention into a single, cohesive operating model. By engineering tight functional accountability, deploying advanced RevOps systems, and orchestrating secure AI automation, I connect every dollar of commercial spend directly to P&L outcomes (NRR, LTV:CAC, and EBITDA). 📊 PROVEN RESULTS & IMPACT CAC Optimization: Decreased client CAC from $521 to $12 via precise cohort targeting. Return on Spend: Achieved peak campaign ROAS of 74.67x. Funnel Velocity: Generated conversion rate lifts above 115% across the mid-funnel. Platform Execution: Led complex HubSpot, Salesforce, and unified RevOps architecture builds across growth-stage technology, fintech, healthtech, and capital portfolios. 🎯 WHAT I DELIVER 1. Revenue System Audit & Blueprinting (The Revenue Engineering Sprint) A fixed-scope, deep-dive audit identifying pipeline leakage, operational friction, and tech stack redundancies. I deliver an objective, data-backed blueprint sequencing the exact strategy, timeline, and resources required to optimize your commercial engine. 2. Agentic RevOps & AI Automation Systems Moving beyond basic automation to build autonomous multi-agent workflows. I design high-governance HubSpot/Salesforce architectures, citation infrastructure (AEO/LLM optimization), and real-time insights that gives leadership an unassailable source of revenue truth. 3. Fractional CMO (The Full-Funnel Navigator) Embedded C-suite leadership focused on market positioning, global GTM execution, performance media, and AI-enabled demand generation. I transition marketing from a cost center into a predictable pipeline engine with strict compliance guardrails. 4. Fractional CRO (The End-to-End Revenue Engine) Unifying Marketing, Sales, and Customer Success into a high-velocity revenue motion. I own cross-functional metrics alignment, sales process optimization, predictive forecasting models, and Net Revenue Retention (NRR) strategy to maximize enterprise value. ⚙️ TECH & CAPABILITY STACK CRM & RevOps: HubSpot (Certified) · Salesforce · Marketo · Microsoft Dynamics Data Science & Financial Modeling: Python · R · SQL (LTV, CAC, churn prediction, algorithmic segmentation) AI Architecture & AEO: ChatGPT · Claude · Jasper · Perplexity · Custom Multi-Agent Orchestration Analytics & BI Intelligence: GA4 · Looker · Tableau · Power BI · Mixpanel · Amplitude · Heap · PostHog Performance & Programmatic Media: Google Ads (Certified) · Meta · LinkedIn · YouTube · The Trade Desk · DV360 ABM & Intent Data: 6sense · Demandbase · Bombora Revenue Intelligence & Lifecycle: Gong · Clari · Outreach · Salesloft · Clay · Apollo · Segment · Automated Override Protocols 🏭 INDUSTRIES SERVED Technology and SaaS, Financial Services and Fintech, Healthcare and HealthTech, Consumer Goods and CPG, Construction and Manufacturing, B2B Services, B2C, D2C Ecommerce, PE/VC Capital Portfolios 🚀 HOW ENGAGEMENTS WORK 1.
