What I'm looking for

I seek senior engineering roles building scalable web platforms with MERN/TypeScript, strong API design, performance focus, and collaborative, growth-oriented teams.

I am a Senior Full Stack Engineer with over 10 years of experience building scalable web applications across SaaS, FinTech, eCommerce, and Healthcare using the MERN stack, NestJS, and TypeScript. I design REST and GraphQL APIs, build responsive React UIs with Redux and Tailwind CSS, and create modular backend architectures that improve performance and reliability.

I have led development of large-scale platforms, implemented MongoDB optimizations and aggregation pipelines, built NestJS services and Node.js microservices, and delivered CI/CD pipelines with Docker and GitHub Actions. I mentor engineers, drive API design and performance improvements, and build real-time features with WebSockets and Socket.io to enhance user experience.
