About
Hi, I'm Ratnesh
I'm a full-stack developer in Ahmedabad with four years of shipping production web apps — Angular and React on the front, Node and Postgres behind them. Before any of that, I was a microbiologist.
The story
I did my master's in microbiology and went to work at Pfizer, deploying a laboratory information management system across production and R&D labs. On paper the job was about software compliance. In practice it was about the gap between how a lab actually works and how a system assumes it works — and about persuading three departments to change their habits.
I found I cared more about that gap than about the science on either side of it. So I spent two years teaching myself to build things properly before asking anyone to pay me for it.
What carried over from the lab was the notebook. Every procedure, every result, every failed experiment — written down, dated, kept. That instinct came with me, and it shows up aswell-documented code and commits you can still read a year later. It also left me unable to assume anything works until I've watched it work.
The other thing that carried over is patience with complicated systems. Biology doesn't yield to brute force; you understand it incrementally or not at all. Most of the hard problems I've hit since have had exactly that shape.
