Small, useful things built for the web
Sahas & Co is a one-person studio in Kolkata. I build websites, web apps and internal tools — and I publish a few of my own, like the Durga Puja guide that thousands of people use every October.

Websites that load fast
Static, secure and cheap to run. No plugins to break, no monthly hosting bill that grows on its own.
Web apps and tools
Calculators, directories, dashboards, booking flows. If a spreadsheet has outgrown itself, it probably wants to be a small app.
SEO and structured data
Schema markup, sitemaps, Search Console setup, and the technical work that decides whether Google can read your site at all.
Progressive web apps
Installs on a phone like an app, works offline, no app store review. Often the sensible alternative to a native build.
A project you can actually look at
Festive Kolkata — Durga Puja 2026
A free guide to 210 Durga Puja pandals across Kolkata and West Bengal: 2026 themes, the nearest metro station for each pandal, bus corridors, crowd timings, food and toilets. In Bengali, English and Hindi. It installs on a phone and keeps working when the network dies in a crowd.

- Fixed scope, fixed price. You know the number before work starts.
- You own everything. Code, domain, accounts, all of it in your name.
- Plain language. No jargon in invoices or status updates.
- Built to hand over. If you want to take it in-house later, nothing stops you.
