About us:
The name comes from “Sabyasachi” — an epithet for Arjuna in the Mahabharata, meaning someone equally skilled with both hands. It felt right for a group of people who move comfortably across the stack: backend, frontend, mobile, data, infra — whatever the problem needs.
We're a small, tight-knit collective of engineers based in Dhaka, building for clients worldwide.
We believe the strongest businesses aren't held together by spreadsheets and good intentions — they run on systems built to last. That's why we build software people actually want to use, document everything as we go, and ship things that work in production, not just in demos.
We are shobyoshachi:
A small collective of engineers who started by building our own systems first. We run our own internal tools and infrastructure — end to end — and bring everything we learn from that to the work we do for clients.
We're early, and we'd rather be straight about that than oversell it. What we have is real, shipped work: a live mobile app, a product with thousands of downloads, and a credit-scoring engine that's been through real bank validation.

What it's like to work with us:
Before we write a line of code, we write the plan. Every project starts with a requirements document and a system design so you know exactly what you're getting — no surprises halfway through a build.
We deliver in working increments, not a black box for three months. You see progress continuously, give feedback early, and always know where things stand.
When we hand something over, we hand over everything — source code, documentation, deployment setup, and enough context to run it without us if you ever need to.
