About

I’m a 22-year-old computer programming student building small open-source tools around developer workflows, testing, and AI-assisted coding. I’m still learning, but I like building real projects in public instead of only doing tutorials. My recent work includes tools like Tautest, which helps check whether AI-written tests actually protect behavior using mutation testing. I’m interested in software architecture, testing, cybersecurity, CI workflows, and making AI coding tools more reliable in real projects.

tautest - Mutation testing workflow for AI-written tests

Tautest is different because it combines mutation testing with an AI-agent workflow. It uses StrykerJS as the engine, then adds changed-line PR scoping, surviving mutant reports, AI-ready fix prompts, and GitHub sticky comments. Instead of only asking whether tests pass, it asks whether tests fail when the changed code is mutated. It is built for teams using Claude Code, Cursor, Codex, or Copilot who want stronger test feedback without calling any LLM API itself. CLI and CI ready. Open source!!!
