What I'm looking for

I'm looking to deliver reliable, secure software through manual and automated QA across web, mobile, API, and financial systems. I value cross-functional collaboration, complex product challenges, strong quality practices, and opportunities to improve automation and production readiness.

I've delivered QA across client-facing financial services, asset management, B2B2C payment, inventory, and mission-critical mobile and web applications at INITS. I validate complex workflows including investments, settlements, virtual accounts, RBAC, financial deductions, offline synchronization, and data reconciliation.

At United Bank for Africa Plc, I led end-to-end QA for core banking modules, designed 500+ test cases with 98% coverage, and helped resolve 30+ critical defects before go-live. I support UAT, validate accounting and financial transaction flows, and work closely with developers, product managers, business analysts, and stakeholders to move products toward production readiness.

At DIGA Technologies, I led and mentored three QA engineers and built Cypress automation that reduced regression effort by 40% per release. I bring a developer's perspective through JavaScript, TypeScript, React, and modern test automation using Playwright, Cypress, Selenium, Postman, JMeter, and AI-assisted QA workflows.
