👋 About Me

I'm a Systems Engineer at Tata Consultancy Services (TCS) in Mumbai with ~2 years of experience running and securing enterprise banking applications. I graduated with a B.Tech in Information Technology from RAIT, DY Patil University (CGPA 9.72).

My day job is infrastructure-heavy, so I build on the side to sharpen my software engineering skills. I'm now working towards a Full Stack / Backend Developer role at a product-based company.

  • 📚 Currently learning: System Design (HLD), Low-Level Design, and agentic AI with Claude
  • 💬 Ask me about: IIS administration, security code review, application migrations, MERN, and AWS deployments
  • 📖 Outside of code: I love reading books and meeting new people

💼 What I Do at TCS

  • Administer IIS across 20+ production servers, including security hardening and request filtering compliance
  • Ran Fortify SAST security code reviews and remediated 100+ vulnerabilities
  • Coordinated large application migrations (SGBS, PM Schemes, eKYC Gen5)
  • Investigated production incidents end-to-end and wrote formal root cause analyses (for example, a recurring app pool crash across 10 servers traced to a message queue backlog plus a latent threading bug)
  • Day-to-day stack: C#, ASP.NET MVC, IIS, Oracle SQL

🚀 Projects

  • Auth with JWT (cross-domain cookies), real-time features with Socket.io, payments with Razorpay
  • Deployed on AWS (EC2, S3, SES, Nginx), later migrated to Vercel + Render
  • Solved real deployment problems: CORS, SPA routing on Vercel, cross-domain cookie flags, MongoDB Atlas IP whitelisting
