I'm Mariusz Budzisz, a self-taught full-stack engineer with 7+ years of commercial experience. I build and operate production software end to end, primarily in C#/.NET and TypeScript/JavaScript. The clearest proof is MyHub: _Website not available. Sign in: https://www.twine.net/signup_ a subscription-video SaaS I designed, built and run on my own: React/TypeScript frontend, ASP.NET Core (.NET 10) backend, PostgreSQL, an ffmpeg HLS transcode pipeline, VR (DeoVR) playback, a custom OAuth 2.0 authorization server, Stripe billing, OpenAI integration, and edge delivery on Cloudflare Workers/R2 - all under Docker with GitHub Actions CI/CD. I work AI-native: the Claude CLI is my daily driver, and I've shipped two agent tools of my own - an MCP server and a headless Claude worker. I'm comfortable navigating unfamiliar codebases, debugging intricate pipelines, and validating non-trivial implementations, and I do my best work with CLI-heavy environments, large monorepos, and full end-to-end ownership.…I'm Mariusz Budzisz, a self-taught full-stack engineer with 7+ years of commercial experience.
