Architect who views code through the lens of business value.
As a DISC Dominant (D) profile, my natural drive is to remove obstacles and automate everything repeatable: from code quality checks (Rector, PHPStan), through automated tests, to dynamic test environments and deployments.
However, the true secret of stable business lies in atmosphere and peace of mind. I deeply believe that a confident and cohesive development team can safely deploy code to production even on Friday afternoons without stress. This is guaranteed by hard quality rules and technical maturity.

Drives me toward continuous process improvement. I don't accept developers wasting time on manual repetitive operations. When performance issues arise, I seek solutions at the source by designing optimal tools.

My Tech Ecosystem
Complete range of tools enabling rapid design, testing, and stable hosting of business systems.
Breakthrough Achievements
Specific deployments that brought measurable financial savings and simplified business processes.
High-Scale A/B Testing System
As Tech Lead, I led a team to create a modern A/B testing system for a high-traffic platform. Fast user redirects, precise activity tracking, and advanced reporting were built on Kafka, RoadRunner, Swoole, React and containers in a Kubernetes cluster.
On-Demand Test Environments
I designed and deployed from scratch a complete, automated CI/CD pipeline enabling automatic creation of temporary, independent development environments for each development branch. I used Docker, Traefik, Rancher and dynamic runners. This reduced QA time by over 40%.
Flow PHP (ETL) Support
I actively support and develop the open-source ecosystem, including the popular Flow PHP framework — focused on high-throughput ETL processing in PHP. Maintaining excellent code quality standards, I implement static analysis tools and QA tests for smaller companion tools.
3 Years of Volunteering at Orphanage
During high school, I weekly visited a local orphanage where I voluntarily managed the computer lab. My responsibilities included software selection, physical computer hardware repair, securing and cleaning systems from virus infections, and basic training for staff and residents.
