Shah Newaj Rabbi Shishir

Senior Software Engineer with 6+ years of experience building scalable, production-ready web applications using Angular and full-stack JavaScript. I specialize in developing large-scale Angular platforms and have worked on systems used by 3,000+ active users, including national-level certification and enterprise applications. In my current role, I design and ship end-to-end features such as configuration workflows, evaluations, and results processing, with a strong focus on performance, maintainability, and clean architecture. I’ve also built POS and back-office applications used by 1,500+ users, managing orders, payments, roles, subscriptions, and device integrations. My tech stack includes Angular (latest versions), TypeScript, RxJS, Ionic, React, NestJS, REST APIs, MongoDB, PostgreSQL, and CI/CD pipelines. I work effectively in remote-first, async teams, communicate clearly, and take full ownership of features from idea to production. I’m seeking a fully remote senior frontend or full-stack JavaScript role where I can contribute to high-impact products and long-term growth.
