At Capgemini, I build end-to-end commercial solutions—from requirements analysis and Java/Spring business logic to Angular frontend delivery. I design scalable services, integrate external APIs, and optimize database queries for data-heavy projects.

Previously at Cinkciarz.pl, I delivered full-stack features for a financial platform, covering database design, Java/Spring logic, and dynamic Angular interfaces. I also support CI/CD, Docker containerization, OpenShift deployments, and Helm-based delivery while using AI tools to optimize code and automate tasks.
