Senior Backend Engineer, Cluj-Napoca
I build backends that stay fast when it matters.
An engineer, not a frameworker. PHP, Go and Python in production; TypeScript and AI agents for everything else.

Senior Backend Developer (PHP)
FameUpRemote, Romania
- Built an agentic bug-fixing pipeline: bugs reported in Slack are picked up, fixed and tested by an agent; developers only review and merge.
- Cut network traffic by 95% by moving image delivery from S3 to Cloudflare Images: every image is resized on the fly to the exact format the mobile apps or the backend ask for, cached with targeted invalidation, and served from Cloudflare’s global CDN.
- Improved CI/CD for agentic development: automatic deployment on merge, parallel tests, PHPStan at max level and AI code review.
