What I'm looking for

I’m looking for a fully remote role where I can own backend architecture end-to-end, build resilient cloud-native services, and improve reliability with CI/CD, async workflows, and clear documentation for global distributed teams.

I’m a Senior Backend Architect and autonomous international B2B contractor who engineers resilient, cloud-native software platforms out of high-friction operational workflows.

In EU/US production environments, I’ve owned critical, high-concurrency backend infrastructure end-to-end under real-time pressure. With Laravel, PHP, MySQL/PostgreSQL, and async microservices, I designed validation/processing/storage pipelines that reduced production errors by ~80% and eliminated ~99% of file loss.

I’m highly disciplined in asynchronous remote work—bringing proactive transparency, airtight documentation, and seamless communication across distributed teams. I’ve built and operated backend services and CI/CD Docker deployments on AWS, mentored junior engineers, and delivered logistics and travel-tech systems using robust backend architectures.
