Software engineer · India
I’m Nitin. I build dashboards, APIs and the web apps around them.
I’m a full-stack software engineer at Fractal Analytics, working mostly in Python and React. This site holds the projects I build alongside my day job and the notes I keep while building them.

About
Software that answers a real question
Most of my work is on analytical dashboards for enterprise clients: the screens people use to answer questions, and the APIs and data work underneath them. Since 2018 I’ve also built REST APIs, e-commerce features, web scrapers and a battery simulator web app.
I studied computer science, then took a master’s in data science. Away from the keyboard I’m usually on a mountain trail or reading philosophy.
