What I'm looking for

I seek remote roles where I can diagnose and fix complex TypeScript systems, create LLM training data, and lead incident recovery with clear documentation and measurable impact.

I am a TypeScript specialist with 5+ years in full-stack development, complex system debugging, and infrastructure recovery. I routinely identify, reproduce, and document async and scaling-related bugs across code, servers, and databases, and have restored critical corporate data after domain/hosting loss.

I convert hands-on debugging expertise into clear, step-by-step training data for large language models, documenting edge cases, failure scenarios, and improvement suggestions to enable autonomous diagnosis and repair of TypeScript and software issues. I am available for remote freelance contract work with secure, high-speed setup and flexible hours.
