What I work across

Different kinds of work, kept separate.

Roles, product projects, coursework, and learning sit in their own buckets so nothing is mixed together.

Products

Commerce and mobile projects with user-facing flows and practical engineering constraints.

Quality & delivery

I am a full-time Quality Assurance Engineer at Kolosal since July 2026, after starting there part-time in January 2026. Before that, I worked as a DevOps Engineer at NGOPER from January to April 2026.

Learning & systems

Study work and systems experiments, including AI/LLM learning and container tooling. Coursework lives on the projects page.
