Curiosity is the
through line.
My first program was a Windows Batch script. That curiosity became a practice: build something, understand it deeply, then help someone else do the same.
I turn complex systems into usable products, clear docs, and better developer onboarding. My work spans backend services, protocol documentation, trading research systems, and DevRel programs for technical teams.
