Backend reliability
API bug fixing and regression testing
A reliability-focused project for API behavior, targeting reproducible defects, validation edge cases, inconsistent responses, and regression coverage around critical flows.
Role
Bug reproduction, API fix support, and regression test planning
Stack
Node.js, TypeScript, API testing
Services
Bug reproduction, Backend fixes, Regression testing, Technical notes
Challenge
Several core flows returned inconsistent results under edge cases, making frontend behavior harder to trust before launch.
Solution
We isolated the failing cases, corrected the response logic, checked related paths, and documented the validation steps for future maintenance.
Outcome
The affected API flows are more predictable, easier to reason about, and supported by clearer regression notes.
