What I'm looking for

I'm looking to keep building production-ready full-stack systems, modernizing codebases, and expanding my technical toolkit through challenging engineering work.

At Grupa ELKA, I manage full-stack development and feature delivery for the core RODO Online application, including an Audit module built independently from scratch. I also maintain a Java backend supporting secure data import/export and cross-company transfers.

I've modernized legacy CakePHP codebases, improved the reliability and performance of a Java data-processing engine, and delivered more than 50 technical solutions across multiple projects. I value clean, efficient, maintainable code and continue expanding my toolkit through hands-on work in JavaScript, SQL, APIs, Docker, and system design.
