Tell me what is broken

What I build

Web applicationsAdmin panels, stores and internal tools, from the first screen to production.
APIs and backendsServerless or server, with a database and login you can trust.
AI assistantsAssistants that answer from your own catalogue and hand off to a person.
IntegrationsMake two systems agree: orders, stock, invoices, payments.
Data and ETLMove data between systems and shape it into reports you can read.
Urgent fixesReproduce it, fix the cause, add the test that fails without the fix.
Legacy rescueKeep the old system running while it is made safe to change.
Hosting and serversDeploy it, host it and look after it: Docker, Linux servers, AWS and Oracle Cloud, backups.

Any language, any stack: PHP, TypeScript, Python, Java, C++, SQL, and whatever the job needs.

First you send it.

A few lines on what is broken or needed. No form, no call required.

Then I take it apart.

You get a written scope, a price and a date back, before any work starts.

You choose one.

Hourly, fixed price or monthly. You approve the one that fits.

It ships.

Tested, running, and handed over with notes you can read in six months.
