FAQ
My API was working for months and suddenly started throwing 500 errors. What would cause that?
Most common causes: a recent code change broke something, a dependency was updated, a database schema change, or an environment/configuration change (connection string, secrets). Send me your error logs and recent git commits and I'll find it.
I don't have error logs — the error just says "500 Internal Server Error." Can you still help?
Yes. First step is enabling detailed error logging (I'll show you how), then we capture the actual exception. Even without logs, I can often trace the issue through the code.
Can you fix EF Core issues specifically?
Yes — EF Core is one of my strongest areas. Migration errors, N+1 queries, lazy loading issues, relationship configuration problems, query translation failures — all covered.
What if the bug is complex and takes more time than expected?
I'll communicate with you immediately if scope is larger than expected. I never silently go over scope. We'll agree on any additional work before I continue.
After fixing my bug, can you do ongoing support?
Yes. Many clients move to a monthly retainer after their first fix. Message me about this after we've worked together.
