Senior QA Engineer with 6+ years of experience across manual testing, Python automation, API validation, SQL, AI/LLM tooling, and security-minded release work. I own quality for production software and gaming products: regression strategy, defect triage, and the automation that keeps the same bugs from coming back.

About

Primary QA owner, with Python, AI, and security in the same toolkit.

I design and run quality for production systems: regression, functional, API, database, and end-to-end testing. The work sits next to developers and stakeholders, with clear defects, reproducible evidence, and stable releases.

I also write Python automation, run a Linux lab, and use self-hosted AI tooling. Security is part of the job, not a side note: exploit validation, network debugging, and hardening before something becomes an incident. The 3D CV world is the playful map of that career.
