I’m ALI ROSHANZAMIR, a Senior Frontend Engineer specializing in Angular, with 7+ years of experience architecting and scaling production applications from Angular v5 through Angular 22. I build UI that’s fast, accessible, and maintainable—using TypeScript, RxJS, Angular Signals, and modern component architecture—while also mentoring teams and improving delivery workflows with AI-assisted frontend tooling. Beyond frontend, I’m comfortable working full-stack: I’ve integrated GraphQL and REST APIs, and built backend services with Node.js (Express, NestJS) plus SQL/NoSQL data modeling across PostgreSQL, MySQL, and MongoDB. I’m proud to have contributed to official Angular open-source (merged into core) and created published Angular libraries and learning resources, including a portfolio that achieved top Lighthouse scores.
