Hi, I'm Jakub 👋

I'm a freelance PHP developer focused on custom e-commerce systems, integrations and backend development. I’ve been building web applications for 17+ years, with most of my recent work centered around long-running, high-traffic e-commerce projects.

What I work with

• PHP 8.4+
• Nette Framework
• Doctrine ORM / DBAL
• MySQL / MariaDB
• Redis
• Elasticsearch
• RabbitMQ
• Docker
• GitHub Actions
• Cloudflare

What I usually build

• custom e-commerce platforms
• order, warehouse and inventory systems
• payment and POS integrations
• third-party API integrations
• search and product filtering
• internal administration tools
• background processing and automation
• performance improvements and system maintenance

I prefer practical solutions, simple architecture where possible, and code that remains understandable several years later. Over the years I've picked up a lot of hands-on knowledge of how e-commerce actually works in practice - not just the code, but the business logic, edge cases and operational quirks that come with running a store long-term. I also make use of AI-assisted development (Claude Code and similar tools) to speed up day-to-day work - from scaffolding and refactoring to research — while keeping the architecture and decisions in my own hands. Most of my commercial work lives in private repositories, so this profile represents only a small part of what I work on.

Selected projects

• Goldea.cz - custom multi-market e-commerce platform
• AutoHotarek.cz - automotive accessories e-commerce
• ROBOT WORLD - robotics and smart-home e-commerce
• Technimax.cz
• LGshop.cz

Currently spending a lot of time on:
