I take on work in three shapes. If your problem does not fit one of them, say so anyway — I will tell you honestly whether I am the right person.
One codebase across mobile and desktop, shipped in demoable increments.
Building Flutter applications end to end — mobile, desktop, or both — with the backend behind them. Weekly builds you can run yourself, source in your repository from the first commit.
A till that talks to its hardware — and keeps talking when the network doesn't.
Connecting point-of-sale and kiosk software to fiscal printers, payment terminals and government fiscal APIs, behind an interface your team can actually test against.
A codebase your next hire can run on day one instead of week two.
Taking an ageing Spring or plain Java system and making it maintainable again — without a rewrite and without stopping the business that depends on it.
