About

I’m a Senior Software Engineer at Pine Labs in the Digital Payments team, working on POS platforms and payment controllers for card and multi-currency transactions. My work involves C++ (11/14/20), ISO 8583 messaging, Spring Boot, JWT, C# and secure API integrations with partners like ENBD. Previously, I was a Software Engineer at Intimetec, contributing to RfIdeas card reader management tools using C++, Node.js, and WebAssembly. I developed desktop and SDK solutions for remote card reader configuration and WebHID integrations, while optimizing cross-platform performance. I also worked on HP DUNE printer firmware, gaining hands-on experience with C++, networking stacks, and QML for UI development. I hold a B.Tech in Computer Engineering from Poornima Institute of Engineering & Technology (2022), with strong foundations in algorithms, data structures, and web technologies. I have certifications in HTML, CSS, Python, and a published research paper on front-end development methodologies. Passionate about solving real-world problems through technology, I enjoy mentoring junior developers, building scalable systems, and continuously learning. Outside of work, I love cricket, singing, and traveling.
