Senior Software Engineer · India
I’m Nitin. I build UI dashboards, Rest APIs, RAG systems and the web apps around them.
I’m a Senior Software Engineer at Fractal Analytics, working mostly in Python and React and, recently with large language models (LLMs). This site collects 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 I started working professionally in 2018, I’ve also built REST APIs, e-commerce features, web scrapers and a battery simulator web app.
I also build retrieval-augmented generation (RAG) systems and LLM-powered features for those clients, using LangChain, LlamaIndex, vector databases and LLM APIs. AI coding assistants are part of how I write software every day.
I started writing code in 2015, when I began studying computer science, and later took a master’s in data science. Away from the keyboard I’m usually on a mountain trail or reading philosophy.
