Fixed-fee C# API review

Know where your C# API really stands.

You depend on your API, but you're not sure you've applied all the best practices. I'm Mathias; for 20 years I've done one thing: C# REST APIs. Send your code, get one plain verdict: what's solid, what's risky, what to fix first. A fixed-fee review, never billed by the hour.

About the reviewer
01Depth in one thing

You get twenty years of experience on a very specific code stack: C# REST APIs, the OData layer, EF Core and SQL Server, the parts that must not break.

Your code is measured against the best practices I use myself: clear boundaries (DDD), confidence in automated deployments, guaranteed delivery of events, tenant isolation, tests you can trust.

Outside that? I tell you before you pay.

02You always know who read your code

One person reviews your code: me. Start to finish.

No queue of anonymous developers, no juniors you never meet. The person you talk to is the one who read it.

03Why it's all in writing

Everything happens online, on purpose. My customers are in many time zones, and a call time that suits me is the middle of the night for you.

A written review is something you keep. I read all of your code before I say anything, you read the result when it suits you, and your team can share it and come back to it.

You can add a short recording (a Loom, for example) to show me your system and your worries. I review with that context.

Prefer to talk first? A call is optional and free. Just ask.

04Start with a test

Two short tests show roughly where you stand, before you share a single file.

For developers

A quick, scored check of how exposed your system is, with a summary you can pass on.

Take the developer test
For managers

The same in plain business terms: what the risk is and what it costs to leave it.

05Why a test first

Don't hand your code to someone you don't know yet. The test tells you whether there's anything worth a closer look before you share a file.

07Get in touch

Questions before you share any code? Ask me anything. I answer the same working day.
