I’m a senior Angular engineer with 7+ years of experience modernizing enterprise front-end applications. I lead legacy Angular modernization and migration initiatives, especially across Angular 20, TypeScript, RxJS, NgRx, and single-page architecture—focusing on performance, reliability, and maintainable engineering standards. I also bring an agentic development approach to my day-to-day work: I translate product and migration requirements into scoped tasks, use tools like Claude Code and OpenAI Codex in a human-in-the-loop workflow for repo analysis, refactoring, migration planning, test generation, and documentation. I’ve consistently driven measurable improvements such as lower error rates, faster load times, reduced bundle sizes, and smoother onboarding through clear architecture and coding standards.…I’m a senior Angular engineer with 7+ years of experience modernizing enterprise front-end applications.
