I find the root cause. Then I write it down so it stays found.

Python developer and product support engineer in Bengaluru. I work on enterprise data platforms by day, and I've written and self-hosted a 579-page reference library — close to a million words, all mine — started in 2019 and maintained ever since.

Public Notes Library

Roughly 952,000 words I wrote myself, self-hosted with no publishing platform behind it.

Problem
Six years of research notes locked in a private vault, useful to nobody else.
What I did
Authored in Obsidian, exported to static HTML, designed the information architecture, and self-hosted it behind a custom subdomain router.
Outcome
579 pages across 15 sections and 146 linked reference PDFs — online since 2019 and still maintained.

Vijay Electro Works

A bilingual storefront for an electrical shop in Hazaribagh, Jharkhand.

Problem
A shop with no online catalogue, and customers who search in Hindi.
What I did
Built and deployed it solo in Next.js: priced catalogue across eight categories, WhatsApp ordering, contractor wholesale section, Maps directions.
Outcome
A live demo on Vercel, Hindi-first with English navigation — the full storefront, not yet taking real orders.

// about

Chemical engineer by degree, Python developer by practice. My day job is enterprise data platforms — TLS handshakes, proxy misconfigurations, gateway outages, and the log analysis that explains them to a customer who needs an answer today.

Outside it I build and maintain static sites, automate the parts of my own work that repeat, and finish long projects. The shape is always the same: take something dense, find the actual cause, write it down so the next person starts further along.
