About Me

I'm a backend engineer specializing in Go and backend systems for complex software products.

Since 2019, I've built services and domain models across industrial software, search, and natural language processing. My recent work focuses on carbon calculation workflows, API design, and time-series data processing.

I design reliable systems around user needs while keeping long-term product evolution in mind.
