Gameplay Programmer

PunitSehrawat.

Building interactive systems — one mechanic at a time.

From sketching game ideas on paper to building them in Unity — I've been designing gameplay mechanics long before writing a line of code. Now I turn those ideas into real, playable systems.

Background

The Story So Far

I build gameplay systems and interactive experiences. Currently interning as a Game Programmer at Yellow Cap Games, developing core loops and mechanics for an upcoming mobile title.

Previously at Blood Nexus Studio (remote), I contributed to "Sheriff Showdown" — a 2D mobile shooter — designing and implementing the shop UI and checkpoint persistence systems.

Pursuing my B.E. in Computer Science Engineering (Graphics & Gaming) at Chandigarh University.
