I build SaaS products end to end with Next.js, Node.js and Python, and ship AI features that are actually used: RAG, agents and speech-to-text.

React and Next.js apps with Tailwind, React Query and realtime UIs. Shipped CRMs, booking flows and editors.
Node.js, Express and FastAPI APIs on MongoDB and PostgreSQL. Stripe/Paddle billing. Docker and PM2 deployments.
Agents with the OpenAI Agents SDK and LangGraph, RAG on vector databases, speech AI with Whisper and AssemblyAI.
A few things I have built and shipped.
This site: a self-hosted Next.js platform with a RAG chatbot, streaming AI agents and a talking 3D avatar of me.
A browser-based video editor for creators and social media teams, built at Evolvo (QuantumBytes).
A CRM for photographers, planners, DJs and booth pros: proposals, payments, client portal and marketplace.
