Things we’ve built that are running right now.

A certification body with a working store, and no way for anyone to try a test before paying for one. Sign-in was split across the estate, so an account on one site was useless on the next.

The practice-test platform from an empty repo: an authoring system with its own registry of question types, test composition, an import that carried the whole live question bank across, the attempt engine and scoring, a coin ledger, a coupon gateway into the certification store, an admin console and a learner dashboard. One sign-in now works everywhere in the estate.

A visitor takes a test without signing up, sees a score, signs up for the answer sheet, earns coins and spends them against a certification. The team authors and publishes without us.

Courses, plans and tests each lived somewhere different, and anyone paying from outside India saw the wrong price.

A commerce-and-learning site: the course catalogue, subscription plans, free tests, deals, one-tap social sign-in, and pricing that switches to the visitor’s own currency by country — wired to the shared question bank so a test is the same test on either site.

Learners buy a course or a plan, sit a free test first, and pay in the currency they actually use.

A second brand had to grow on the same practice-test content without the two banks quietly drifting apart.

The practice-test store and the bank behind it, with custom modules for how tests are packaged and priced, sharing one question bank with the sister site.

One bank of practice tests feeds two storefronts, and a change lands in both at once.

The whole business ran on spreadsheets and phone calls — orders, dealers, invoicing, and the accounts that all of it had to agree with at the end of the month.

The operation end to end, from an empty repo: an API-first core, role-based access, order management and a fulfilment centre, GST-correct invoicing, a dealer portal, business chat for the whole sales floor, notifications, and one shared money library so every rupee agrees across the web, the apps and the accounting sync. The storefront was rebuilt on the same core.

Sales, dispatch and accounts work from the same orders, and month-end reconciliation is a report rather than a week.

Years of books living in paper and spreadsheets, and a firm’s worth of clients who each needed their own set kept straight.

The product from an empty repo: many companies under one login with plans and billing, bank-statement import with column mapping it remembers, a rules engine that categorises the entries that repeat, an approval step before anything posts, invoices and payments, backups, and assisted categorisation for the ones the rules have not met. An import can be undone as a whole run, not unpicked row by row.

A firm imports a statement, reviews what the rules did, approves it and moves on. If the run was wrong, the whole run reverses.
