PatrykOstrzolek/README.md

Hi, I'm Patryk 👋

Full Stack Developer with 9+ years of commercial experience — PHP/Symfony on the backend, React on the frontend. I've built affiliate platforms, financial lead-generation systems, API integrations with external partners, and e-commerce storefronts on Magento PWA Studio.

What I'm focusing on 🌱

I'm currently expanding my backend and platform engineering skills, with a focus on:

  • Domain-Driven Design (DDD) along with naturally fitting approaches like CQRS, ES and hexagonal architecture (P&A)
  • Asynchronous processing with RabbitMQ, and the Saga pattern for distributed workflows
  • CI/CD and infrastructure automation with GitHub Actions, Ansible and Terraform
  • Headless architectures (Sulu CMS + Next.js / JAMstack)

About this profile 💻

These repositories are a direct continuation of what I did commercially — API integrations, system architecture, backend/frontend ownership — just pushed further on my own terms. php-event-driven-lab is the flagship one: a series of PHP projects moving from hand-rolled implementations to Symfony EventDispatcher/Messenger, covering domain events, CQRS, event sourcing and the Saga pattern. The rest are educational projects and technical experiments where I document what I learn along the way.

I use AI tools like Claude Code as part of my workflow — they speed up exploration and boilerplate, but the architecture decisions, understanding and debugging are mine.
