I design & build end-to-end web platforms — from modern frontends to cloud-native backends.

Senior full-stack engineer with 8+ years of experience delivering solutions for the public sector, finance, healthcare, retail, logistics and education. Strong on both frontend (React, Angular, Vue, ASP.NET, JSF/Thymeleaf) and backend (REST/gRPC APIs, microservices, event-driven systems), with deployments using Docker, Kubernetes and CI/CD pipelines.
