About

A bit about me

The short version of how I got here and what I care about when I'm writing code.

I'm Ashfaq — most people call me Ash. I've been building on the web for a little over six years, and I still get the same kick out of shipping something that holds up in production, especially when it saves someone hours of manual work or clears a bug that's been sitting around for months.

I picked up coding seriously in college — hackathons, workshops, organizing an AI club, leading a Google Developer Student Club chapter. Smart India Hackathon, NASA Space Apps, DevFest — that's where I learned how to move fast, ask dumb questions early, and actually finish things with a team. A lot of how I work today came from those years.

Right now I'm at Rhythm Healthcare in Hyderabad, building software that clinicians and patients actually rely on. Healthcare has a higher bar: your data model has to be right, migrations can't take the system down, and "we'll fix it later" isn't really an option. That kind of problem-solving is what I enjoy most — AI triage pipelines, large billing migrations, front-end rebuilds, whatever moves the product forward.

Before Rhythm, I co-founded Ezerka and spent two years leading a small engineering team — client calls, architecture, reviews, deployments, all of it. Before that, Cognizant (Verizon's email platform) and Rubicon Red (logistics dashboards) taught me what long-lived enterprise codebases look like and how to improve them without breaking what already works.

I try to write code the next person can follow, document decisions while they're still fresh, and be straight about timelines. If you're hiring, exploring a collaboration, or just want to talk through a technical problem — feel free to reach out.
