What I'm looking for

I’m looking for senior backend roles where I can lead architecture and teams, build scalable microservices, integrate DevOps, and drive product impact.

I am a senior backend developer with 13+ years building scalable, secure systems across Symfony, PHP, microservices, AWS, Azure, and MySQL.

I have led teams and products from ideation to release—founding a SaaS company, managing 10-person teams, and delivering high-load real-time betting systems and enterprise platforms.

At Spencer I refactored legacy systems, implemented CQRS, DDD, Event Sourcing, and helped onboard major clients; at Debricked I migrated a monolith to microservices and implemented SBOM generation workflows.

I bring a founder’s mindset, strong DevOps and clean-code practices, and a focus on product-aligned engineering to drive maintainable, high-performance systems and measurable business outcomes.
