Clarity is the ultimate optimization.

I enjoy building Android and web experiences that feel smooth, fast and intentional. From Bluetooth Low Energy experiments to image processing and complete products, I love turning ideas into working apps.

Hello, I’m Rajeev
Upcoming Systems Engineer at TCS

I’m a Software Developer.

Final-year B.Tech Computer Science student at SOA University, Bhubaneswar. I focus on Android app development, BLE-powered IoT ideas, image processing, and web development. I enjoy designing systems end-to-end — from UI and architecture to deployment.

I’m actively looking for roles where I can build impactful Android or full-stack products and keep learning every day.
