Quality Control Engineer specializing in analytical testing, root-cause analysis, and automation.
NigeriaWhat I'm looking for
I’m an analytical Computer Science graduate building reliable, high-integrity products through systematic problem-solving, root-cause analysis, and rigorous quality control. With 3+ years of hands-on experience, I design test plans, identify defects, and document findings to help teams deliver with confidence—grounded in safety, continuous improvement, and learning agility.
In my current role as a Quality Control Engineer, I run functional and exploratory testing on web-based trading platforms to validate 50+ core transaction, wallet, and order-execution workflows. I also execute API testing across 40+ endpoints with Postman, reproduce issues with developers, validate fixes, and support alpha/beta release cycles by isolating high-impact problems early.
Earlier, I worked as a Web & Mobile Application Test Engineer, designing and executing 300+ test cases and tracking 200+ defects in JIRA to drive an estimated 30% reduction in post-release issues. I built and maintained automated test suites in Cypress and Postman covering 70%+ of critical user flows and APIs, mentored new interns on manual testing methodology, and strengthened regression coverage across 100+ modules per release cycle for government-sector platforms.
