Your product doesn't need another developer who ships fragile code and vanishes. It needs one who takes it from idea to production and keeps it standing after launch. That's what I do. I'm a Full Stack Developer (8+ years) who builds complete products: React/Next.js on the front, Node.js and Python on the back, AI woven in natively, for founders who need to ship fast without rebuilding in six months. I've shipped 10+ live products across fintech, healthcare, e-commerce, and education, including a legal-AI platform that helped its company raise $2M, and a learning platform now used by Yale, Tulane, and 600+ schools. Real products. Real users. Real revenue. Hire me and you get a React developer, Node.js developer, and Python developer in one: a true full-stack engineer who owns the whole build. I work across React / Next.js / TypeScript (frontend), Node.js, Express, and Python (FastAPI, Django) on the backend, and MongoDB / PostgreSQL for data. When a project needs AI, I integrate it natively with OpenAI and modern LLM tooling (RAG, vector databases, AI agents), built into the product, not bolted on as an afterthought. PROOF I SHIP REAL PRODUCTS: • DecoverAI: Legal document search platform. Python backend + React frontend, RAG retrieval over a vector database. Deployed in US law firms; the company raised $2M in seed funding after launch. • Speakology: Avatar-based language-learning platform. React/Next.js + Node.js + OpenAI voice. Adopted by 600+ schools and 12K students, including Yale University and Tulane University. Plus 8 more production apps: healthcare clinical screening, AI sales intelligence, supply-chain forecasting, hospital management, 3D-printing e-commerce, and more. All React / Node.js / Python full-stack builds. WHAT I DO: • Build complete web applications from scratch: React/Next.js frontend + Node.js or Python backend + database • Design and ship REST APIs, GraphQL, and third-party API integrations (Stripe, OpenAI, custom) • Build and scale multi-tenant SaaS platforms and MVPs from idea to launch • Migrate and refactor legacy code into clean, maintainable architecture, no rewrites • Add AI features to existing products: chat, semantic search, automation, RAG, LLM integration • Deploy and run apps on AWS with Docker and CI/CD STACK: Frontend: React, Next.js, TypeScript, JavaScript, Redux, Tailwind CSS Backend: Node.js, Express, Python, FastAPI, Django, REST APIs, GraphQL Databases: MongoDB, PostgreSQL, Redis AI: OpenAI API, LLM integration, RAG, vector databases, LangChain, AI agent development Cloud/DevOps: AWS, Docker, CI/CD HOW I WORK: I write code that matches your conventions, communicate clearly, and ship on schedule. Clients describe the work as "amazing… really dedicated and loves to think along about product improvements," and as understanding requirements quickly and delivering outstanding results. I think about the product, not just the ticket. Available 30+ hours/week and responding within a few hours. Tell me what you're building: a SaaS MVP, an AI-powered web app, an API integration, or a rescue of an existing codebase, and I'll tell you exactly how I'd build it.

I build and stabilize AI automation, agents, and full stack SaaS products that need to work reliably in production, not just in demos. I’ve shipped and scaled systems for founders from Y Combinator, Founders Factory, FutureLabs, and Republic of Work. Founders I’ve built with have gone on to raise €2M+, and my AWS/serverless work ranks in the top 0.2% for DevOps. A few results: ⚡ Multi-tenant SaaS with 28% faster integrations ⚡ Serverless system running under 200ms latency at 10K+ users ⚡ AI RAG system improving support efficiency by 45% ⚡ Next.js migration reducing hosting costs by 15% ⚡ SaaS MVPs shipped to production, with founders raising after launch A lot of products today get built quickly with Cursor, Lovable, Bolt, Claude Code, or an early freelance team. Then real users arrive. That’s when the problems show up: messy code, fragile backends, AI features that worked in the demo but fail in production, scaling bottlenecks, unreliable automations, and rising AWS costs. I help turn that into a production-ready system with clean architecture, a solid backend, reliable AI behavior, and room to scale. I also build new products properly from idea to MVP to production. What I can help with: * AI agents, chatbots, and AI voice agents * Workflow automation and business process automation using n8n, Make, Zapier, and APIs * Production RAG, LLM, and knowledge-based systems * Full-stack SaaS development with Next.js, React, Node.js, TypeScript, JavaScript, and Python * Backend systems, REST APIs, third-party integrations, and multi-tenant architecture * PostgreSQL, Supabase, Stripe, AWS, serverless, performance, and cost optimization * Stabilizing fragile or AI-built MVPs before they become technical debt How I work: We can start small. Send me your app URL, repo, or brief with a short note on the problem. I’ll review the likely bottlenecks, scaling risks, reliability issues, and what I would fix first before you commit to anything bigger. From there, I can take technical ownership of the build: architecture, backend, integrations, AI systems, delivery, and the parts that usually stall. I work best with: * Funded startups starting with or moving beyond MVP * SaaS teams hitting scaling, reliability, or cost issues * Founders who want a senior engineer to take ownership, not just ship tickets I’m probably not the right fit if you’re looking for the cheapest possible build. I’m a fit when the product matters, users depend on it, and it has to work. Tech I work with often: Python, JavaScript, TypeScript, React, Next.js, Node.js, AWS, Supabase, PostgreSQL, Stripe, serverless, OpenAI, Claude, Gemini, RAG, LangChain, AI agents, n8n, Make, Zapier, automation, and APIs. If your product was built fast and now needs to work properly, or you want it built right from the start, send me the repo, app, or brief, and I’ll tell you what I’d fix first.
