Backend PHP Developer (Laravel / Symfony) — AI-first engineering
Almost 6 years building and maintaining production systems: e-commerce, SaaS, and regulated (medical) platforms. Daily user of Claude Code as a coding agent.
Most of my commercial PHP work sits behind client NDAs — these are public repos written specifically to be readable.
Laravel · OpenAI API · React · Docker Compose
Turns an unstructured client brief into a clear action plan — summary, task list, open questions, and risks — using an LLM. REST API backend, React frontend for results.
github.com/kamilszwaradzki/smart-brief-ai →Laravel 10 · REST API
A RESTful task-management API written as an open-source showcase of clean code and layered architecture.
github.com/kamilszwaradzki/php-backend-demo →Laravel
A side project-management tool — another example of code outside NDA-covered client work.
github.com/kamilszwaradzki/project-manager →Client work under NDA — described here, not linked.
ZEN Technology B.V. · Symfony 6, OpenCart, RabbitMQ, Redis
Scaled the backend through a 200% traffic increase within a year without an architecture redesign. Fuzzy search engine built with the adapter pattern, prepared for a future Elasticsearch integration.
Codehome sp. z o.o. · Laravel 9, Vue.js, MySQL
Multi-module medical system — patients, appointments, payments. RBAC authorization and a GDPR-compliant architecture for sensitive patient data.
Webniko sp. z o.o. · Symfony, API Platform, PrestaShop
Invoice management system plus a custom PrestaShop permission module. Fixed a critical Shopify checkout issue affecting live sales conversion.
PHP 7/8, Symfony, Laravel, Doctrine ORM, REST API, PHPUnit
