AI Full-Stack Developer | NestJS - Next.js - OpenAI - LangChain - SaaS
Most developers integrate AI as an afterthought. I build it into the foundation. 5+ years of full-stack experience — and for the last few years, every product I've shipped has had AI at its core, not bolted on at the end. What that looks like in practice: - A SaaS platform where users talk to their data instead of filtering through dashboards - A NestJS backend that doesn't just serve requests — it reasons through them using LangChain agents - A Next.js frontend where AI features feel native, not like a chatbot widget slapped in the corner My stack: → Backend: NestJS, Express.js, Node.js → Frontend: Next.js, React, Electron.js → AI: OpenAI API, Claude, LangChain, RAG pipelines → Database: PostgreSQL, MongoDB, Redis I don't pitch you a generic solution. I ask what your users actually struggle with — then build AI that solves exactly that. If you're building a SaaS product and want AI that actually moves the needle, let's talk. I respond within a few hours.
