At RoaDo, I build AI-driven invoice reconciliation, multi-tenant workflow, and automated resource-allocation systems that eliminate manual billing checks, streamline 10,000+ monthly processes, and save 170+ operational minutes each day.

I've taken ambiguous requirements through production, rescued a delayed release module, and improved API response times from 1.2 seconds to 300 milliseconds as a freelance full-stack developer.

I also contribute to Docker Moby and vLLM, fixing Docker Engine issues and building Rust/Python capabilities for safe request control, while creating AI retail operations tools with Vercel AI SDK, Gemini, Neon Postgres, and Telegram.
