Context
Automated feedback is part of maintaining production backend systems. At EnergyYar, my work includes applying TDD and using unit and integration tests to reduce regressions.
Engineering work
I accelerated automated test execution by approximately 4×. The improvement belongs alongside the broader software-quality work: code review, clean architecture, and mentoring backend engineers.
Outcome
The résumé documents the approximate execution-speed improvement. It does not give a baseline runtime or a mutation/coverage score, and no such measurement is asserted here.
A related engineering question
Fast feedback and useful assertions solve different problems. The Test Quality Lab is an educational exercise in checking whether assertions detect defects; its examples are not EnergyYar code or evidence of a production test implementation.
