Daniel M.
Full-Stack Product Engineer | AI, Web Apps & Systems Programming
I build entire products from scratch. Design, frontend, backend, infrastructure, deployment. Recent work: an LLVM code obfuscation suite with a bytecode VM (23K lines of C++, built in 30 days), a multiplayer game server in async Rust with custom binary protocols, zero-trust certificate auth, and a matchmaking rating system I designed from the ground up. An AI agent that automates reverse engineering through IDA Pro. A writing analytics SaaS with Google Docs integration, OpenAI/Anthropic APIs, and Stripe billing. I work across the stack because most projects need someone who can. TypeScript, React, Python, C, C++, Rust, Node, Postgres, Redis, Docker. I pick based on what the project needs. If you need something built end to end and shipped, that's what I do. I'll tell you what's realistic before I start, and I'll tell you when something isn't working instead of burning hours on it.
