What I'm looking for

I’m looking for a team where I can design and ship high-load PHP/DevOps systems—owning architecture, CI/CD, monitoring, and reliability—while leading small squads and translating business needs into scalable technical solutions.

I’m a senior PHP developer and DevOps and integrations-focused system architect with 16+ years building resilient, high-load platforms. I bridge business requirements with technical solutions, and I’m most effective leading small to medium teams to deliver outcomes.

Across my roles, I’ve reworked legacy systems, built microservice platforms from scratch, and operated distributed infrastructure at scale. I designed and implemented monitoring and reliability improvements so teams can move faster with confidence.

I bring end-to-end ownership—architecture, deployments, networking, automation, and continuous delivery. From Proxmox-based automation and migrations to containerization and CI/CD, I focus on measurable reliability, reduced downtime, and practical engineering standards (SOLID, TDD, code reviews).
