What I'm looking for

I’m looking for a team where I can modernize and stabilize Angular/Java/Spring Boot systems, collaborate across QA/DevOps, and use AI-assisted workflows to improve code quality and reduce manual overhead.

I’m a “Mid-Level Full Stack Engineer” with 2+ years of professional experience building, maintaining, and optimizing enterprise-grade Angular and Java/Spring Boot systems. I investigate and resolve defects across frontend, backend, gateway, data, and infrastructure layers, coordinating with QA, DevOps, and business teams to deliver stable, maintainable solutions.

I actively integrate AI-powered tools (Claude Code, OpenAI Codex, ChatGPT, Cursor) and agentic automation workflows into my daily development to accelerate delivery, improve code quality, and reduce manual overhead. I also lead modernization work—bringing Angular from v11 to latest versions—and rely on clean architecture, SOLID principles, and CI/CD-supported release cycles to keep engineering practices consistent.
