Most AI features are demos. Mine create proposals, send emails and answer customers at 2am while your team sleeps. I'm an AI Full Stack Web Developer with 9 years building SaaS real businesses run on. I build complete web applications, not just the AI layer: React and Angular frontends, Node.js, Laravel and FastAPI backends, PostgreSQL and MySQL databases, and AI agents, RAG chatbots and automation that do real work inside the application rather than sitting bolted on the side. AI DEVELOPMENT - AI agents that take real actions through APIs: creating records, generating proposals, managing products and services, and sending emails on request - RAG chatbots (Retrieval Augmented Generation) that answer questions from your live application data and business knowledge - AI customer support chatbots that answer customers whenever your human support team isn't available - AI document extraction that reads uploaded files and drawings and turns them into structured data - FastAPI services and tool-calling APIs that connect the AI layer safely to the rest of your platform I build AI to be reliable in production, not impressive in a demo: answers grounded in your own data, structured AI output validated against a schema, and permission-checked actions so an AI agent can never do something the user couldn't. FULL STACK WEB DEVELOPMENT AND SAAS - Custom web development and web applications, from first build to production - Software architecture and system design for scalable, secure SaaS platforms - SaaS development with multi-tenant architecture, role-based permissions and secure authentication - Payment integration with Stripe, including subscriptions, refunds, webhooks and payouts - Booking platforms, marketplaces and paid content platforms - Taking over existing codebases and enhancing them without breaking business logic, permissions or APIs - React Native mobile apps, from build through App Store release - AWS deployment, Docker and CI/CD pipelines TECH STACK AI: AI agents, RAG, AI chatbots, AI customer support automation, LLM integration, FastAPI, Python Frontend: React, Next.js, Angular, TypeScript, Tailwind CSS Backend: Node.js, Express, Laravel, PHP, REST APIs Database: PostgreSQL, MySQL Cloud and DevOps: AWS, Docker, GitHub Actions, CI/CD Clients hire me as an AI Full Stack Web Developer when they need one person who can own the frontend, backend and AI layer, understand an existing codebase quickly, and ship without breaking what already works. I still maintain most of what I've built, some of it for years. That changes how you write code from day one. If you're building something with real users and real money moving through it, tell me what it is and I'll tell you honestly how I'd approach it.
