Freelancer profile translated to English.

Description

I build products that stand up in production.

8 years designing solid backend architectures for fintech, mobile, and SaaS platforms — NestJS, React, Flutter, AWS. I've delivered international payment systems, iOS/Android event apps, and banking interoperability platforms in startup environments where the margin for error is slim.

What motivates me: complex problems, fast-moving teams, and products that have a real impact.
