Saiprem Katkam

Full-Stack Web Dev · Unity Game Developer

Hey there! 👋I'm Saiprem, recently graduated with a degree in computer science and game development.

I've spent my time building across two worlds — web and games.

•On the web side, I work with React, Node.js, and PostgreSQL — building full-stack apps that are clean, fast, and actually make sense to use.
•Games are where I got started. I've built 2D and 3D games in Unity using C# — I care as much about how a mechanic feels as how it's built.
•I like problems that need both technical thinking and a bit of creative instinct. If it runs in a browser or a game engine, I'm probably already curious about how it's built.

Here are my socials
