About Me

Aryan Choudhary
B.Tech CS (AI & ML)

Engineering student who builds things end to end and cares more about how data moves through a system than how it looks on the surface. I'm most comfortable when I understand both sides of a feature, backend logic and frontend usability in equal measure.

I gravitate toward workflow-driven problems: scheduling systems, access control, automation pipelines. And I care about building them to scale, systems that hold up when more users show up, not just when it's one person testing locally. Not looking for the easiest path, looking for the one where I actually learn something.
