About Me

I build custom web applications, internal tools, and automation systems for startups and small businesses.

I help turn spreadsheets, manual workflows, or early product ideas into working software — from backend and database design to frontend, deployment, and integrations.

My background is 10+ years in Kotlin/Java backend engineering, APIs, integrations, and scalable systems.
