At QUANTOO SP. Z O.O., I independently design, develop, and modernize backend systems for Gremi Media, including a central CMS and publishing platform used by rp.pl, parkiet.com, zyciewarszawy.pl, and archiwum.rp.pl.
I design REST APIs and integrations between systems, and develop editorial workflows, article versioning, and publishing mechanisms. I also work with DevOps on application infrastructure, performance, and scaling.
I implemented production AI integrations with OpenAI and Google Gemini for article correction, and ElevenLabs for generating audio. I also develop asynchronous workflows with Symfony Messenger and RabbitMQ.
Earlier, I developed PHP and Symfony applications and microservices at RANKOMAT.PL, and web applications at QUANTOO SP. Z O.O. I started out as a freelance web developer, delivering projects for small businesses.
