Still doing things manually that AI could automate? Let's fix that. → Implemented AI automation + CRM marketing systems for a US marketing agency "made our workflows much more efficient… highly recommend him for CRM, AI automation, and marketing optimization" (verified testimonial on this profile) → Code-rescued a broken custom Trello API portal, then deployed, enhanced, and extended it — same client came back 4 contracts in a row → Built automations, integrations, and web systems for a logistics platform (RoadLedger) — "understands requirements quickly, communicates clearly" (5★) 🔧 What I build: → Workflow Automation: Lead capture, invoice processing, CRM updates, data syncing between your tools. Set up once, runs forever. → RAG Chatbots: ChatGPT trained on YOUR docs and data. Your customers or team ask, it answers with sources. Instantly. → AI Agents: They read, analyze, decide, and act across your tools. Email triage, data enrichment, reports. While you sleep. → API Integrations & Rescues: Stripe billing, CRM/ERP sync, webhooks, scrapers, broken third-party APIs. The plumbing that has to just work — I also fix the ones other developers abandoned. → Full-Stack Web Apps: When you need the whole product — Next.js, Node.js, PostgreSQL, deployed and documented. 🛠 Tech: AI: OpenAI API · Claude API · RAG · LangChain · pgvector Automation: n8n · Make · Zapier · Webhooks · REST APIs · Apify · Cron Apps: Next.js · Node.js · NestJS · TypeScript · Python · PostgreSQL · Supabase · MongoDB Integrations: Stripe · Google Workspace · Slack · WhatsApp · Twilio · HubSpot · Shopify · Airtable Why my automations don't break: I'm a software engineer with 8+ years of experience (IBM & BlackBerry certified), Top Rated with 100% Job Success. You don't get a fragile no-code toy — you get error handling, alerts when something fails, and documentation you own. 💬 Message me with one line about what you're doing manually today. I'll reply within 24 hours with a concrete plan and a fixed quote.

Top Rated Plus engineer — 100% Job Success, $100K+ earned on Upwork, 100+ completed contracts, average response under 4 hours. I specialize in AI integration, RAG systems, and AI agents connecting LLMs (OpenAI, Claude, Gemini) to real business data and workflows, and I build the full-stack product around them. I don't build AI demos that die after the prototype stage. I ship production AI features and full applications end to end: architecture, backend, frontend, deployment. 40+ completed projects spanning AI platforms, enterprise SaaS, fintech, healthcare, industrial AI, and more. RECENT WORK: • Kaivo — AI-native OS for agencies. Multi-tenant client portals, CRM workflows, AI operational assistance (Next.js, FastAPI, PostgreSQL). • Viralzy — AI content/social automation platform. Brand-aware LLM generation with agentic workflow orchestration. • Point.Laz — Industrial AI for mining. 3D/LiDAR visualization (React, Three.js) + PyTorch computer vision. • Carbon Giant — Carbon accounting/ESG platform using AI/OCR extraction with auditable calculation logic. • FITCHECK Global — AI virtual try-on platform with diffusion models and GPU-backed inference. • Hallward — Construction intelligence platform parsing Primavera P6 data into risk analytics. Plus: AI email generation for e-commerce, a RAG-grounded AI tutoring platform, a citation-enforced research assistant with MCP support, wearable health-data integration, and multiple fintech/DevOps engagements. Full case studies and live links in my Portfolio section. WHAT I BRING: • AI & LLM: AI integration, RAG pipelines, retrieval architecture, multi-agent systems, chatbot development, Claude/OpenAI/Gemini integration, prompt/workflow design, AI automation. • Full-Stack: React, Next.js, TypeScript, Node.js, Express, Python, REST APIs, microservices, auth systems. • Cloud: AWS, GCP, serverless, Docker, Kubernetes, Terraform, CI/CD (GitHub Actions). • Data: PostgreSQL, MongoDB, MySQL, vector databases (pgvector), data pipelines, API integrations. HOW I WORK: I take on a limited number of projects so each gets real attention. Before code gets written, I want to understand the actual problem and who it's for — usually a short scoping conversation covering what you're building, what's in place, what "done" looks like, and where the risk is. I work in clear milestones so you see progress and can give feedback early. I write code meant to be maintained: tests where they matter, documentation for handoff, architecture that scales past v1. BEST FIT FOR: • Startups building or adding an AI feature to an existing product • Teams that need AI integration, a RAG system, or an AI agent built right the first time • Companies scaling a full-stack app who want one person to own both the AI layer and the product • Anyone burned by a prototype that never made it to production AVAILABILITY: Generally available for new contracts, typically responding within a few hours. Comfortable with hourly or fixed-price, async or scheduled calls, standard tools (Slack, Jira, Notion, GitHub). Open to contract-to-hire. COMMON QUESTIONS: "What do you need to start?" A short description of the problem, any existing code/assets, and what success looks like. I'll turn that into a scoped plan before work begins. "Early-stage or established companies?" Both — what matters is having a clear enough problem to scope honestly. "Can you sign an NDA?" Yes, standard practice. Send me the details of what you're building. I'll give you a straight read on scope, approach, and timeline before we agree to anything — no inflated estimates, no scope creep.

I'm a Full-Stack Developer with 10+ years of experience building complete web solutions end to end - frontend, backend, cloud, and now AI - for global companies including P&G, BD, and HCL. 120+ projects delivered. 100% Job Success Score. Top Rated Plus on Upwork, the top ~3% of freelancers on the platform. "Full-stack" isn't a buzzword for me - it means I can take a project from a blank page to a live, working product without handing you off between three different specialists. Frontend, backend, database, deployment, and now AI integration - all one person, one point of contact, one consistent quality bar. WHAT "FULL-STACK" ACTUALLY COVERS Frontend Development React / Angular / TypeScript / JavaScript / responsive UI - interfaces that are fast, clean, and built around how real users actually behave. Backend Development C# / SQL Server / REST APIs / Microservices - the engineering underneath that keeps everything reliable at scale. Web Development & E-Commerce Custom web applications plus Shopify and WooCommerce builds - including theme customization, payment gateways, and ERP/CRM integrations that keep your store and your back office actually talking to each other. Cloud & DevOps Azure / AWS / Docker / CI/CD - infrastructure that scales with your business instead of becoming the bottleneck. AI Integration & Automation This is where I go beyond traditional full-stack work: OpenAI/ChatGPT API integration, intelligent workflow automation, and AI-powered features built directly into your product - not bolted on as an afterthought. HOW I WORK I don't just take a spec and start typing. Before writing a line of code, I make sure I understand what you're actually trying to achieve - the business goal behind the feature request - because the fastest way to waste a budget is building the wrong thing well. Once that's clear, I move fast and build it to last: clean architecture, secure by default, and documented well enough that it isn't a black box six months from now. If you need one person who can own a project end to end - design the system, build the frontend and backend, wire up AI where it actually helps, and deploy it properly - let's talk about what you're building.

15+ years. Dozens of products shipped. One consistent focus is building systems that don't break when your business grows. If you're a founder or product team looking for a technical lead who can guide decisions, not just execute tasks, that's exactly what I do. I work with startups, scale-ups, and established businesses to take ideas from early concept through to stable, scalable products. Whether that's an MVP you need to validate quickly, a mobile app ready for real users, or a SaaS platform built to grow, I stay closely involved on the technical side while keeping the broader product direction on track. 𝗪𝗵𝗮𝘁 𝗺𝗮𝗸𝗲𝘀 𝘁𝗵𝗶𝘀 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁 Most developers will build what you ask for. My job is to make sure what we build is the right thing and that it won't need a full rebuild when your user base grows or your requirements change. That means asking the right questions early, flagging trade-offs before they become expensive problems, and making sure every technical decision connects back to your business goals. 𝗪𝗵𝗮𝘁 𝗜 𝗯𝘂𝗶𝗹𝗱 • Mobile Applications — iOS, Android & Cross-Platform • Full-Stack Web Applications & SaaS Platforms • MVP Builds from idea to working product, fast • API Development & Third-Party Integrations • Backend Architecture built for scale • Technical Strategy & Product Planning for founders 𝗜𝗻𝗱𝘂𝘀𝘁𝗿𝗶𝗲𝘀 𝗜'𝘃𝗲 𝘄𝗼𝗿𝗸𝗲𝗱 𝗶𝗻 Healthcare & Mental Wellness · Fitness & Sports · Real Estate · Freight & Logistics · Education & E-Learning · Food & Beverage · Financial Services · Social & Community Platforms Each of these industries comes with its own operational and technical challenges. Having worked across all of them means I can move faster, ask better questions, and avoid the mistakes that slow teams down. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 I value long-term collaboration over quick handoffs. Many of the clients I've worked with have stayed through multiple development stages, because when a team understands your product deeply, the work gets better and faster over time. My working style is direct and transparent. You'll always know where things stand, what decisions are coming, and why I'm recommending what I am. No technical jargon for its own sake, just clear communication that keeps the project moving. Where projects require it, I work with a trusted team of developers I have built and managed over the years. Every team member works under my direct supervision, and I remain the primary technical lead and client point of contact throughout. This means you get the reliability of working with a senior lead alongside the delivery capacity of a full team. 𝗔𝗜-𝗔𝘀𝘀𝗶𝘀𝘁𝗲𝗱 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 I use AI tools like Claude as part of my development workflow. Not as a shortcut, but as a way to move faster without cutting corners. In practice, that means using AI to accelerate repetitive groundwork, explore approaches quickly, and pressure-test logic, while every piece of code that goes into a production system is reviewed, understood, and validated by me before it ships. I don't copy code blindly. AI handles speed. Experience handles judgment. The combination means you get faster delivery without the hidden technical debt that comes from unreviewed, auto-generated code. 𝗟𝗲𝘁'𝘀 𝘁𝗮𝗹𝗸 𝗮𝗯𝗼𝘂𝘁 𝘆𝗼𝘂𝗿 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 If you're building any of the following, I'd like to hear about it: • A mobile app: iOS, Android, or cross-platform • A SaaS product or startup MVP • A scalable web application or backend system • A platform that's grown beyond its original architecture Send me a short brief describing what you're building and where you're stuck. I'll review it and come back with honest thoughts on approach, timeline, and what to watch out for.
