About

My work spans backend development and test engineering. I focus on business logic, validation, and maintainable systems, and I am extending that experience into AI workflows and LLM inference.

How I approach the work

I start with the problem and its boundaries, then work toward an implementation that can be validated. Design records, reviews, and tests help keep a changing system understandable and maintainable.

Current interests

I am extending my Python and test engineering experience into applied AI, while studying LLM inference, cache management, and reproducible experiments. This site keeps engineering projects alongside learning records, distinguishing plans from completed work.
