About this gig

Is your backend shipping to production with zero tests? 

That's a bug waiting to happen.


I'll write a proper test suite that catches issues before 

your users do.


WHAT I WRITE

Unit tests for API endpoints and business logic

Authentication and authorization tests

Database query and ORM tests

Edge cases and error handling

Mocking external dependencies


WHY TRUST ME

I have shipped 150+ tests across production projects

Open source contributions merged by Tim Abbott (Zulip 

founder/CEO) and Lee Calcote (Layer5 founder)

My JPM Quoter service has 35 tests with full circuit 

breaker and Kafka coverage

WHAT YOU GET

TECH

IMPORTANT

Message me before ordering. Send me your codebase 

or the specific functions/endpoints you want tested.

I will confirm scope and timeline before you pay.
