About

Professional summary

I am a Quality Assurance Lead and Product Analyst with more than four years of experience in telecommunications, fintech, and pharmaceutical quality assurance.

I specialize in functional, integration, UX, performance, USSD, and API testing for mobile and web products. I design test cases, manage defects, review requirements, and ensure end-to-end traceability across critical customer journeys.

I lead and coordinate QA teams across multiple African markets, collaborating closely with product, development, operations, third-party partners, and business stakeholders. I am comfortable facilitating communication between French-speaking and English-speaking teams.

My work is focused on improving product reliability, customer experience, and time-to-market. I have reduced critical defects before production releases and shortened testing cycles through process optimization and proactive risk management.

I also bring a strong product mindset, using customer journey analysis, KPI tracking, defect metrics, and product gap analysis to recommend improvements that support adoption, conversion, and revenue growth.

I am ISTQB certified and trained in Agile/Scrum, product management, product strategy, and product analytics. I am committed to continuous improvement, collaborative leadership, and delivering high-quality digital financial services.

Career history

QA Lead - Customer Experience & International Coordinator MoMo Group from MTN

I lead and motivate QA testers across subsidiaries in Ivory Coast, Cameroon, Benin, Ghana, Zambia, and Uganda. I coordinate critical testing phases with product teams to ensure new features meet business objectives, user expectations, and quality standards.

I define and implement functional, UX, and performance testing processes for the MoMo application. I support multilingual stakeholder communication, facilitate French-English testing meetings, analyze product gaps, investigate anomalies, and recommend customer-experience improvements.

I contributed to the deployment of the Next Gen MoMo application across six African markets. I reduced critical defects by 30% before release and shortened validation cycles from five days to three days, improving time-to-market and team productivity.

Quality Assurance & Testing Engineer MTN Cameroon

I coordinated and executed integration and functional testing for Mobile Money services, including insurance, bank transfers, loans, digital payments, remittances, USSD, and customer integrations. I tested across the MoMo App, MoMo USSD, and Ericsson CC GUI and Partner GUI platforms.

I performed requirements reviews, designed and executed manual test cases, managed defect lifecycles, conducted root cause analysis, and communicated testing outcomes to stakeholders. I also worked with Product, development, QA, operations, and third-party partners to prioritize work and meet delivery milestones.

I coordinated functional testing for the XtraTime lending migration from Mode to Optasia with zero customer complaints, supporting recovery of more than 600 million CFA francs in debt. I also supported the GameOver initiative and MoMokash integration testing, contributing to substantial Mobile Money revenue and platform stability.

Quality Assurance Officer Africure Pharmaceuticals S.A

I conducted inspections and testing of raw materials, components, and finished pharmaceutical products to verify compliance with industry standards and specifications.

I participated in multidisciplinary quality projects and maintained quality rules, regulatory requirements, procedures, and processes. I prepared process-validation protocols and reports in accordance with cGMP guidelines.

I executed process validation through monitoring and sampling at defined parameters, supporting compliant and controlled manufacturing operations.
