Real projects with real numbers. Client systems are described anonymously — the profile, the problem and the results are genuine; the names stay confidential.
Full replacement of a field-operations system — with a mobile app and no app stores
An aging cloud system with a separate native Android app, replaced by a single modern .NET system with a field PWA — push notifications, offline mode and camera included. Core development took 12 working days.
- 12 working days of core development
- 38,000+ equipment units migrated
- Push and offline on iPhone and Android
Modernizing an 823,000-line monolith — no downtime, no big bang
A live .NET Framework 4.8 platform with 54 projects and 23,000 commits of history, modernized incrementally to .NET 10 — the old system keeps running while the new one takes over section by section. 19 sections with tests in about 8 days.
- 823,000 lines of legacy code
- 19 sections in ~8 days
- SSO with zero changes to the old system
SportBattles — our own SaaS platform for racket-sport tournaments
A tournament management platform — from draws and scheduling to live scoring and online payments. Built and operated entirely by us; the proof that we can carry a product from idea to market.
- ~190,000 lines of our own code
- 11 draw algorithms
- 660 automated tests
From a system with a 2011 UI to a new product in 9 weeks
An internal market-data system of 237,000 lines, built on UI components 14 years out of date, rewritten as a new product. The analysis before the code proved 65% of the old system was dead — the client paid only for what was alive.
- 9 weeks to a new product
- 65% of the scope cut after analysis
- 237,000 lines of legacy code analyzed
A shipment portal displacing an established competitor — in 4 months
A business shipping portal with live rate comparison across carriers, native integrations with six carrier networks and label printing — from zero to a product displacing an existing competing solution.
- 4 months from zero to a working portal
- 6 carrier integrations
- Nightly automated E2E tests
Your GPS data already exists — make it useful
An existing GPS platform collected 50,000 messages a day from the fleet, but its built-in reports didn't work. We built an analytics layer on top — anomalies, reports and scores over data the company was already paying to collect.
- 50,000 messages a day processed
- 18M historical records
- Reports in milliseconds instead of minutes
