🏆 Top Rated | Full-Stack & AI Developer | React, Next.js, Node.js, Python I help startups and SaaS founders turn ideas into production-ready software — full-stack web and mobile apps with AI built in, not bolted on. Top Rated on Upwork, I ship systems real businesses run on every day. I've delivered end-to-end products across SaaS platforms, e-commerce, healthcare, logistics, and internal business automation — owning each one from architecture and design through development, deployment, and scaling. My focus is the same on every project: clean, maintainable code and systems that stay fast and reliable as they grow, not just demos that look good in a screenshot. What I build: - Modern web and mobile apps — Next.js, React, and React Native on the front end - Solid back ends — Node.js, Python, and well-structured REST APIs - Reliable data layers — PostgreSQL, Supabase, and MongoDB - The integrations products depend on — Stripe payments, Twilio comms, Google Maps, and third-party SaaS workflows AI & automation: - OpenAI- and LLM-powered features, chatbots, and AI agents - Workflow automation that handles real operational work — customer support, content generation, data processing, and internal tooling that saves teams hours of manual effort Built to last: - Secure foundations — authentication, role-based access control, and real-time features - Scalable database architecture, so your product is ready for real users from launch — not patched together later How I work: You get clear communication and steady progress, not silence followed by a surprise. I plan the architecture before I write it, keep you updated as the build moves, and make decisions with scaling, security, and maintainability in mind from day one. The goal is software you can hand to real customers with confidence. Industries: SaaS · E-commerce · Healthcare · Logistics · Internal business automation Core stack: Next.js · React · React Native · Node.js · TypeScript · Python · PostgreSQL · Supabase · MongoDB · OpenAI API · LLM / AI Agents · n8n · Stripe · Twilio · REST API integration
