01About

Full Stack Engineer with 6+ years of experience designing and building scalable, cloud-ready enterprise applications with TypeScript, JavaScript, Node.js and React.

Strong in REST API design and integration, backend microservices, and distributed, real-time data flows — with a track record of building reusable component libraries and micro frontend platforms that improve developer productivity and delivery speed.

Solid engineering fundamentals across system design, testing, debugging, performance and reliability, delivered through CI/CD in agile, cross-functional teams. Mentor to junior engineers, and keen to apply AI-assisted tooling and automation to simplify developer workflows.

    Senior Software Developer

    • Developed and maintained secure backend services using Node.js, NestJS and LoopBack, integrating with internal REST APIs and legacy systems to power real-time data streams consumed by the frontend.
    • Designed and developed modular, scalable micro frontend applications using React and TypeScript — independent, composable components decoupled from specific data sources for maximum reuse across teams.
    • Optimized Webpack build pipelines with code splitting, lazy loading and tree shaking, reducing bundle sizes by 15–20% and improving initial load times.
    • Managed complex application state with Redux, keeping frontend components synchronized with backend microservices.
    • Built high-performance, responsive UI with a strong focus on accessibility (WCAG), cross-browser compatibility and visual consistency.
    • Worked closely with architects, QA, designers and business teams to deliver compliant, stable releases on tight timelines in an agile environment.
