What I'm looking for

I’m seeking hands-on engineering roles where I can build secure e-commerce and blockchain payment systems, work in collaborative Agile teams, and drive measurable business impact while growing technically.

I am a software engineer with a computer science background and 5+ years developing e-commerce, finance, mobile app, and backend systems. I focus on combining modern web and blockchain technologies to deliver secure, production-ready solutions.

I have built and deployed Solidity smart contracts, integrated Web3 libraries into front ends, and created secure payment modules supporting Stripe, PayPal, Razorpay, and crypto payments. I’ve optimized API performance, reduced checkout failures, and improved system reliability using Docker, CI/CD, and cloud platforms.

I enjoy working in Agile teams, taking ownership of end-to-end features, and solving security and performance challenges. I’m motivated to apply my technical skills to real-world business problems and continue growing through collaborative, impact-driven projects.
