What I'm looking for

I’m looking to build secure, scalable full-stack web apps—high-performance React frontends and reliable Node.js/TypeScript APIs—while contributing to Agile teams focused on code quality. I’m especially excited to integrate AI-driven features into modern web applications.

I’m a results-driven Full Stack Software Engineer with 3+ years of hands-on experience architecting and delivering MERN stack solutions in production environments. I build scalable React.js frontends with complex state management and design robust Node.js/TypeScript REST APIs with secure JWT authentication and RBAC.

I’ve translated Figma into pixel-perfect, role-aware React experiences, and I centralize auth/error handling to keep delivery consistent across modules. I also optimize performance (Vite, memoization, lazy loading), build PCI-DSS compliant Razorpay payment workflows, and use Redis/RQ with scheduled jobs to handle heavy processing without impacting UX.
