# Full Stack & AI Developer | React Native | Node.js | NestJS Hi, I'm a Full Stack and AI Developer who enjoys building products from idea to production. Over the last 10+ years, I've worked on React Native mobile apps, scalable Node.js/NestJS backends, web applications, and more recently, AI-powered products and automation. I like owning the entire development process—from architecture and APIs to mobile apps, deployment, and ongoing improvements. I've shipped 30+ production applications across iOS, Android, and the web, working with startups, founders, agencies, and growing businesses. ### What I do * Build cross-platform mobile apps with React Native (CLI & Expo) * Develop scalable backends using Node.js, NestJS, Express, PostgreSQL, MongoDB, and Redis * Design REST and GraphQL APIs * Build AI-powered applications using OpenAI, Claude, Gemini, Llama, RAG, AI agents, and workflow automation * Integrate payment gateways, authentication, push notifications, deep linking, and third-party APIs * Deploy applications on AWS, Docker, Kubernetes, and modern cloud infrastructure * Improve performance, fix production issues, and modernize legacy applications ### Full Stack Development I prefer owning both the frontend and backend because it keeps development faster and avoids unnecessary back-and-forth between teams. Whether it's a mobile app, web application, or backend service, I make sure everything works together smoothly. My typical stack includes: * React Native * React * Next.js * Node.js * NestJS * TypeScript * PostgreSQL * MongoDB * Redis * AWS * Docker ### AI Development AI has become a major part of my work. I build AI features that solve real business problems, including: * AI chatbots * AI voice agents * Customer support automation * Healthcare AI assistants * Sales assistants * AI workflow automation * Document search using RAG * LLM integrations * Custom AI APIs Instead of simply adding AI for marketing purposes, I focus on making it useful, reliable, and cost-effective. ### Recent Projects * Marketplace platform with React Native and NestJS * AI healthcare assistant with conversational workflows * Audio streaming application with offline support * Multi-vendor delivery platform with live tracking * SaaS platform with React Native, NestJS, PostgreSQL, and AWS * AI-powered business automation tools for healthcare and enterprise clients ### How I work I believe good communication is just as important as writing good code. You can expect: * Clear architecture discussions before development * Regular progress updates * Clean, maintainable code * Daily communication * Practical solutions instead of unnecessary complexity * Long-term support after launch Whether you need a new product, want to modernize an existing application, or are looking to add AI capabilities to your business, I'd be happy to discuss your project. If you have an idea, let's talk and see how we can build it together.
