Dmytro Strafun
Software Engineer & Solution Architect
Summary
Engineering leader with 16 years in software and 8+ years building and running teams. I set technical direction, hire and grow engineers, and own architecture and delivery end-to-end. I’ve scaled a platform from 0 to 50,000 subscribers and led teams through migrations, compliance, and reorganisation without losing pace. Hands-on where it counts (PHP, Node.js, Python, Go, distributed systems), and currently driving LLM tooling adoption as a real multiplier on team velocity and code quality.
