I'm leading quality engineering for Safaricom Ethiopia's M-Pesa portfolio, building cross-platform testing frameworks for systems supporting 150K+ active merchants and 45M+ monthly transactional states.
I introduced Appium/Dart continuous testing that reduced production regression bugs by 40% and accelerated releases by three business days. I also designed data-integrity testing for low-connectivity scenarios, helping isolate synchronization anomalies by 40%.
Across Safaricom's core mobile infrastructure, Chronos Fintech's digital banking platform, and Exceed IT Solutions, I've validated transactional flows, offline synchronization, APIs, real-time events, responsive interfaces, and OAuth 2.0 security controls. My work has included GDPR-focused validation, SQLite and Hive database testing, contract testing, performance profiling, and exploratory testing.
I care about maintainable quality practices and have mentored four mid-level QA engineers through BDD/TDD practices and Gherkin-based testing.
