Build dependable software around real business workflows.

I build and improve backend services, APIs, internal tools, and web applications with a focus on maintainable architecture, clear domain logic, and safe delivery. I can own a scoped product slice or work alongside an existing engineering team.

Senior delivery without unnecessary ceremony.

I am most useful on software where business rules, integrations, data, and production reliability matter more than framework fashion.

My core background is PHP and Symfony, complemented by modern frontend, API, database, testing, and AI-assisted development practices.
