Product Manager at Angu taking a contactless transit payment platform from concept to launch across NFC POS, commuter wallets, and merchant settlement.

At Angu, I took a contactless transit payment platform from concept to launch, connecting NFC POS, commuter wallets, and merchant settlement. The solution achieved wide adoption among commuters and merchant partners and became a leading cashless payment method in public transportation.

At HumanManager Limited, I led product management for the HumanManager suite and expanded it with payment, salary-loan, LMS, SAP, and Oracle integrations. I also launched a bank-facing white-label payroll offering and led a mobile app redesign that increased employee engagement by 35% within six months.

At SystemsSpecs Technology Services Limited, I managed the HumanManager enterprise HR and payroll platform and built an SME-focused mini payroll product from ideation through post-launch optimization. It expanded the company’s reach into the MSME market across Africa and grew the SME customer base by 28% within the first year.

I began in product analytics at SystemSpecs Limited, using SQL and Excel to analyze HumanManager usage and inform product decisions. Earlier, as a Systems Engineer at Sunnet Systems and Datacomm Services, I contributed to enterprise infrastructure deployments, migrations, and network security work.
