I build production web apps and AI-powered backends. My last app hit 540+ monthly active users within two months of launch. Next.js on the frontend, Python (FastAPI/Django) or Go on the backend. Recent projects • A policy-enforcement gateway for AI agents, built as a TypeScript/Node SDK with tamper-evident audit logging and LLM-based evaluation using OpenAI and Open Policy Agent • An app shipped on play store with 540+ Monthly active users within 2 months of shipping • REST and streaming APIs in FastAPI and Go, containerized with Docker and deployed through CI/CD Stack Frontend: Next.js, React, TypeScript, Tailwind, SvelteKit Backend: FastAPI, Django, Go, Node.js AI/LLM: OpenAI & Gemini APIs, RAG, agent tooling, MCP servers, prompt evaluation Data: PostgreSQL, MongoDB, Redis Infra: Docker, CI/CD, GCP/AWS How I work You get a staging link early, small reviewable commits, and a message whenever something changes. I ask questions before building so I don't build the wrong thing, and I write code and documentation the next developer can actually read. Available 30+ hrs/week and open to long-term contracts. Message me what you're building and I'll tell you honestly whether I'm the right fit.
