Case Studies

The constraint, the call we made, and what shipped

These are written by sector rather than by client name. Most of what we build ships under a client's own developer account, so we treat every engagement the same way: the engineering is described in full, the client isn't named, and every claim is tagged with how you can check it.

Networking

Building a sound-based SDK and app that swap professional profiles between nearby phones, without QR codes

A professional networking startup wanted people at events to exchange profiles just by standing near each other. We built the Flutter SDK that sends and detects identity tokens over inaudible sound, the main app on top of it, and an example app for other developers.

Community

Building a multilingual lost-and-found pet app where the map stays fast and repeat API calls are cached

A national lost-and-found pet platform wanted its reports, alerts and vet search in one mobile app, in three languages. We built it in Flutter on the platform's existing backend, with a TTL cache in front of the API and two map instances so filtering stays responsive.

EdTech

Building a civil-services exam prep platform where every descriptive answer reaches a human evaluator

A regional civil-services coaching institute wanted prelims practice, mains answer-writing, mentor evaluation, peer review and paid courses in one app. We built it in Flutter on Supabase, with evaluation modelled as data rather than as a screen.

POS / Retail

Three roles, one app, and a Saturday with no internet

For a multi-location salon group — owner, supervisor and cashier see three genuinely different products, enforced in the data layer rather than the interface.
