About me

PHP / Laravel Backend Developer | APIs, integrations & maintenance

I develop web applications and take over systems that need fixes, modernisation or further development. I have worked commercially with PHP since around 2021 and with Laravel since June 2022.

I can help with:

PHP 8+ / Laravel backends, REST APIs and integrations;
bug fixes, SQL optimisation, queues and caching;
Docker / CI/CD deployments and Linux administration;
access control, MFA, Cloudflare and production troubleshooting.

I work with PostgreSQL, MySQL/MariaDB and Redis, with React/TypeScript when frontend work is needed. I diagnose first, agree on scope and risks, and document delivery and handover.

Portfolio: device provisioning in Laravel 11, zeskanuj.com and remediation of a production DDoS incident.

Remote projects and ongoing collaboration. Indicative rate: PLN 150/hour excluding invoice VAT; fixed-scope work quoted individually. Message me on Useme with the problem or change you need.
