What I'm looking for

I’m looking for a product-minded team where I can build full-stack features end-to-end, improve code quality, and tackle real technical debt while working with Agile/Scrum and data-driven systems.

I’m a Full Stack Developer with 2+ years of experience building and maintaining web applications in Agile teams. I focus on shipping reliable features while improving code quality and reducing technical debt across frontend, backend, and data-driven systems.

In my current role, I develop public-facing applications with React, TypeScript, Angular, and Spring Boot, and I’ve delivered measurable impact by designing reusable Vaadin components that reduced code volume by 62.5%. I also led a major database migration, moving 100+ Oracle packages, tables, and functions to PostgreSQL.

I bring a practical, full-cycle mindset: I’ve configured Docker-based local environments and identity services with Keycloak, supported legacy JSF work inside microservices, and built data-focused solutions such as a React/Flask weather platform with PostGIS and RAG-based semantic analysis of corporate reports.
