About

Hi! I’m a Full Stack Engineer with 3+ years of experience building scalable, production-grade applications across fintech and healthcare domains. I work across the stack — from designing robust backend systems to building responsive frontend interfaces and ensuring product quality through automated testing. On the backend, I specialize in building scalable APIs and microservices using Node.js and NestJS, with a strong focus on performance, security, and system design. On the frontend, I have experience developing user interfaces using React, focusing on usability, performance, and clean architecture. I also bring experience in automation testing using tools like Cypress and Playwright, helping ensure reliability and reducing manual testing efforts. In my experience, I have: • Built and optimized GraphQL APIs for real-world applications • Designed microservices-based architectures for scalable systems • Worked extensively with MongoDB, Redis, and AWS • Integrated payment systems using Razorpay and Stripe (invoicing, webhooks, refunds) • Implemented authentication, role-based access control, and secure data handling (JWT, encryption, key rotation) • Developed AI-integrated backend features using LLM APIs for intelligent workflows • Built responsive frontend features using React • Improved product quality through end-to-end automation testing I enjoy building end-to-end systems, solving complex backend problems, and creating scalable applications with strong engineering fundamentals. Currently, I’m exploring opportunities where I can contribute to high-impact teams and grow further in backend architecture and system design.
