I build scalable AI-powered full-stack applications and enterprise platforms.
PolandWhat I'm looking for
I've built scalable enterprise applications at The Codest, Edvantis, Syberry, and Polcode, spanning CMS/CRM platforms, administrative dashboards, asset-management PWAs, brokering platforms, and educational simulation engines. My work connects robust backend architecture, high-volume databases, and responsive interfaces.
At The Codest, I architect modular middle-tier systems, optimize MySQL schemas and stored procedures, and build diagnostic tooling that turns competitive data into usable management insights. I also contribute to CakePHP and Zend framework core development, while bringing 10+ years of experience across AI technologies, React, Angular, Node.js, PHP, cloud ML services, and modern frontend engineering.
