Nov 2022 - Mar 2024 • 1 yr 4 mos

Developed and maintained front-end applications using Angular 10 and TypeScript for CRM and Employee Management product modules, delivering 40+ features used by internal business teams. • Built 10+ reusable, responsive UI components, which cut repeated markup and form-handling work across the CRM and HR modules and took roughly two hours off each new feature build. • Integrated Angular applications with REST APIs across 19 modules and screens, implementing data binding, form handling, validation, search/filter, pagination, and error handling. • Implemented Angular services, routing, route guards, and RxJS/HttpClient data flows to improve maintainability, security, and navigation. • Used Swagger and Postman for API documentation, testing, and debugging, resolving integration issues and reducing API-related defects. • Wrote 40–50 Jasmine and Karma unit tests covering the components and services I owned, which noticeably reduced the regressions coming back from QA release over release. • Investigated and fixed 20–25 production defects across UI, integration, and functional layers, improving application stability. • Worked in an Agile/Scrum team using Git and Bitbucket for branching, pull requests, and code reviews across 4 projects.
