What I'm looking for

I'm open to senior backend and platform engineering roles where reliability, scalability, and clean architecture matter.

At Sameday Romania, I architect and maintain a Symfony ticketing platform that processes 10,000+ daily tickets for logistics operations. I reduced API response times by 35% and helped achieve 99.9% uptime through query optimization, caching, CI/CD, and monitoring.

At 2Checkout, I engineered payment features for a platform handling 50,000+ daily transactions across 200+ countries. I led the migration from a monolithic PHP application to 12+ microservices, reducing deployment cycles from days to hours.

At Softia, I built homeowner.ai, a property management SaaS platform, from architecture design to production deployment. I developed its Laravel backend and REST APIs, and implemented a Vue.js frontend for multi-tenant operations.

I also founded Hirely, an AI-powered interview platform built end-to-end from architecture to production. It is used by 50+ companies conducting 100+ interviews daily.
