Shahzer Najeeb

Full-Stack Software Engineer with 6+ years of hands-on development experience building production systems across multiple domains, including fintech, HR-tech, and marketplace platforms, and across multiple environments ranging from early-stage startups to growing organizations and large enterprises.

Strong across the full stack, with particular depth in backend architecture, distributed systems, and performance, alongside substantial experience building complex frontend applications, real-time interfaces, and user-focused experiences.

I primarily work with TypeScript, JavaScript, React, Next.js, Node.js, NestJS, Express, MongoDB, MySQL, GraphQL, REST APIs, WebSockets, and AWS.

I’ve designed, developed, and owned systems end-to-end, from architecture and data modeling through implementation, deployment, and production optimization. This includes multi-tenant platforms, financial infrastructure, distributed HR-tech services, marketplace systems, payment and ledger infrastructure, geospatial search, and real-time applications.

I’ve also worked as a founding engineer and technical lead, taking systems from initial design through production, leading engineering teams, and mentoring other developers.
