What we build

Work that's running today

Client names withheld by agreement. Numbers are real.

3,091appointments / year

Six warehouses, one system

A distribution company operating across India

Started as a simple appointment calendar. A year later it runs their operations — capacity-aware scheduling, discrepancy tracking, proof-of-delivery, courier and returns, with 85+ daily users.

677leads, one campaign

From lost WhatsApp leads to a scored pipeline

A sportswear brand running paid ad campaigns

Every ad lead used to land in one WhatsApp account and vanish. A qualifying bot plus automatic scoring turned one campaign's 677 leads into a ranked pipeline sales works top-down.

How we work

  • Two people, no account managers. You talk to the person building your system.
  • Fixed scope, fixed price. Changes are re-quoted, never smuggled in.
  • A written progress update every week. No meeting required.
  • You own the source code on final payment.
  • Based in India, working with UK businesses — with real overlap hours.

Under the hood

The parts you'll never see get the same care: Postgres row-level multi-tenancy — including the foreign-key bypass class of bug most reviews miss — continuous integration that spins up a fresh database for every test run, tag-gated releases, and OIDC-authenticated deploys. Boring, disciplined engineering is the product.
