I build, scale, and optimize high-performance SaaS platforms and AI-powered web applications. From complex Rust backends to modern Next.js frontends, I help founders launch MVPs in 4-8 weeks. Building a successful software product requires more than just writing code — it demands thoughtful architecture, clear system design, and a product-first engineering mindset. Most companies and product teams face at least one of these challenges: • they need to build a complex SaaS platform but lack full-stack expertise • their current product struggles to scale as the user base grows • development slows down because of technical debt or weak architecture • they want to integrate AI workflows but are unsure how to implement them This is where I step in. I design and engineer end-to-end full-stack systems that support real business growth, ensuring scalability, security, and maintainability. 🏆 RESULTS I’VE DELIVERED FOR CLIENTS Projects I’ve built consistently deliver measurable outcomes: • launched SaaS platforms and MVPs in 4–8 weeks, accelerating time-to-market • reduced development and feature-release timelines by 40–60% • automated operations (ETL, API integrations), saving teams 15–25 hours weekly • scaled platforms to smoothly support 10K–50K+ active users • reduced cloud infrastructure costs by up to 30% through backend optimization 💻 WHAT I BUILD My focus is full-stack software development and SaaS architecture. Typical projects include: • end-to-end SaaS platforms (multi-tenant architecture, billing, auth) • AI-powered applications and intelligent automation workflows • Custom CRM & ERP Systems: Building scalable customer management tools with lead tracking, task automation, and custom internal workflows. • high-performance web applications and operational dashboards • scalable backend systems and robust API infrastructure • complex third-party API integrations (Odoo, CRMs, Payment Gateways) ⚙️ MY TECH STACK & EXPERTISE • Backend & Core: Rust (Tokio, Actix/Axum), Node.js, Python, Tauri • Frontend: Next.js, React.js, TypeScript, JavaScript, Tailwind CSS • AI & APIs: OpenAI API, Gemini, Claude, REST APIs, GraphQL • Databases: PostgreSQL, Supabase, MongoDB, Redis, SQLite • Infrastructure: AWS, GCP, Docker, Kubernetes, GitHub Actions (CI/CD) 🎯 TYPICAL DEVELOPMENT SCENARIOS End-to-End SaaS Development Building a SaaS requires connecting multiple layers securely. I help teams design database schemas, robust APIs, and modern frontends while integrating subscription billing (Stripe) and deploying to scalable cloud infrastructure. AI Integrations & Feature Expansion Many products want to leverage AI to increase value. I build AI-driven features like chat assistants, automated content generation, intelligent search (RAG), and data analysis tools directly into existing workflows. Business Automation & Internal Tools Companies often outgrow spreadsheets. I build internal web applications and perform ETL (Extract, Transform, Load) processes that automate operations, connect fragmented systems (like Odoo), and provide clear operational dashboards. 🔄 MY DEVELOPMENT PROCESS To deliver reliable software fast, I follow a structured workflow: Step 1: Requirements & Planning Defining business logic, user flows, and technical requirements. Step 2: Architecture & Database Design Designing scalable backend architecture and secure data models. Step 3: Full-Stack Development Building frontend interfaces and backend services with clean, maintainable code. Step 4: Deployment & Optimization Setting up cloud infrastructure (Docker/AWS), CI/CD pipelines, and monitoring. 🤝 WHO I WORK WITH Most of my clients include: • SaaS startups launching new platforms • product teams needing senior full-stack expertise without the agency overhead • established businesses optimizing internal operations Typical project budgets range from $5K to $50K depending on scope and complexity. 💡 WHY WORK WITH ME? Beyond writing code, I bring product vision, fluent English, and transparent communication. I collaborate closely with founders to translate ideas into technical milestones, avoiding architectural mistakes that kill growth later. My goal is simple: build software that performs reliably today and continues to scale as your users, data, and business grow. 📩 IF YOU’RE WORKING ON: • a new SaaS platform • an AI-powered web application • a complex backend architecture • a business automation system Reach out and share your project details.

I've built 50+ mobile apps, custom software, and web platforms on Upwork: marketplaces, dating apps, healthcare tools, and Twilio/Stripe integrations with a 100% Job Success Score and clients who keep hiring me back for the next phase. Most of my work falls into four buckets: marketplace/on-demand platforms, social and dating apps with real-time features, custom software built around a specific business process, and backend integrations (Twilio, Stripe) that other developers get stuck on. 𝐀 𝐟𝐞𝐰 𝐬𝐩𝐞𝐜𝐢𝐟𝐢𝐜𝐬: I built a job marketplace from scratch with separate seeker, employer, and admin roles plus live chat. I've shipped two dating apps, including one with a custom matching mechanic. I built a customer-tracking platform and an internal tool for managing zone/location data on a map, the kind of purpose-built software that isn't a template, it's built around how a specific business actually operates. I connected a Twilio BYOC SIP trunk to an international carrier's number, working directly with the telecom provider, not just the Twilio dashboard. I've maintained a pet-sharing app (Dogshare) across multiple engagements, including converting it to a two-language build. And I built a healthcare diagnostic app (Hearty Scan) plus its Android counterpart for a client who came back for round two. 𝐖𝐡𝐞𝐫𝐞 𝐈 𝐟𝐢𝐭: - Mobile: Flutter, React Native, Swift, SwiftUI, Kotlin, native and cross-platform - Backend & custom software: PHP, Python, Node.js - Integrations: Twilio (including BYOC/SIP), Stripe, OpenSearch - Data/infra: Firebase, MongoDB, AWS 𝐖𝐡𝐲 𝐜𝐥𝐢𝐞𝐧𝐭𝐬 𝐫𝐞𝐡𝐢𝐫𝐞 𝐦𝐞: I scope before I code , you'll know what you're getting and roughly when, before I start. When something in the spec doesn't add up, I flag it early instead of building around it silently. And I hand off documented code, not a black box, so you're not stuck coming back to me for every small change. If you're building custom software, a marketplace, a healthcare or on-demand app, or need someone who can actually finish a Twilio or Stripe integration without three follow-up calls" 𝐥𝐞𝐭'𝐬 𝐭𝐚𝐥𝐤 𝐚𝐛𝐨𝐮𝐭 𝐰𝐡𝐚𝐭 𝐲𝐨𝐮'𝐫𝐞 𝐛𝐮𝐢𝐥𝐝𝐢𝐧𝐠."
