About Michał

Senior Backend Engineer with over 10 years of commercial experience, specializing in high-performance e-commerce ecosystems.

Why me? I hold a valid PrestaShop Expert Certification (2025-2027), placing me among the top tier of developers for this platform. I combine deep technical expertise (PHP 8, Symfony) with a business-oriented mindset gained through my experience as a CTO.

Core Competencies:

Backend Development: Building scalable applications with PHP 8, Symfony, and Laravel.

E-commerce Mastery: Advanced PrestaShop development (Core modifications, Custom Modules, Legacy Migrations).

Architecture & DevOps: Designing high-traffic systems, database optimization, and CI/CD pipelines (GitHub Actions).

Current Status: While I currently lead technology at Webixa, I also run my own consultancy (Web Berserker) and I am open to remote B2B contract opportunities where I can solve complex technical challenges.
