About Dmytro

Senior PHP/Symfony Developer | 13+ Years | Legacy Modernization & Domain-Driven Design

I help companies turn aging PHP codebases into maintainable, well-tested systems — without rewriting everything from scratch.
Over the past 13 years I've worked across healthcare, e-commerce, and auction platforms in the Netherlands, consistently delivering where it matters most: upgrading PHP 7.x applications to 8.x, designing domain modules using DDD principles, building reliable APIs and integrations (REST, SOAP), and putting solid test coverage in place with PHPUnit and Behat.
What clients typically hire me for:
  • Legacy modernization — PHP/Symfony upgrades, dependency cleanup, security hardening. At Medicore I upgraded a Symfony app from 7.4 to 8.4 and resolved 50% of critical security vulnerabilities.
  • Domain-driven backend design — I've designed SOAP integration modules for Dutch healthcare (iStandaarden iJW), authorization systems used by 800+ organizations, and complex business-logic engines for auction platforms.
  • Reliable delivery — I write tests, I document decisions, and I communicate clearly. I've worked as a freelancer embedded in Dutch product teams since 2022 and know how to ship without friction.
Tech I work with daily: PHP 8.x, Symfony, Doctrine, MySQL, RabbitMQ, Kafka, Docker, Linux.
Based in The Hague area, Netherlands. Available for remote contracts across Europe.
