The work behind the numbers.

Every project here shipped to real users: payment rails moving money across Africa, features serving millions on Reddit, and national identity systems in telecoms. For each one: the stakes, what I did, and what changed.

Kora

Senior QA → Lead QA → QA Manager · Remote · Nov 2021 to Present

Kora is a Lagos-based pan-African payment infrastructure company enabling businesses to accept payments, make payouts, and settle across African payment channels. I built the QA function from zero and now lead a team of 10+ engineers. In payments, every defect touches money, so these projects carried real financial and regulatory stakes.

The stakes and what I didClose

Kora's Card API on the Checkout platform supports cross-border payments in USD, GHS, NGN, and KES. A failed card transaction is lost revenue for a merchant and lost trust for a customer, so release quality was the headline requirement.

What I did

  • Led the full QA initiative for the Cards API launch
  • Designed the test strategy across functional, regression, and automated coverage
  • Built automation into the CI/CD pipeline with Cypress and GitHub Actions

The stakes and what I didClose

Checkout is the front door for every payment Kora processes. I ran a structured JMeter load test campaign to find out how it behaved under pressure before customers did.

What I did

  • Designed and executed a JMeter load test campaign against the Checkout API
  • Identified critical database errors under load that functional testing could not surface
  • Worked with engineering to resolve the bottlenecks before they reached production scale

The stakes and what I didClose

Kora's Identity Verification tool helps merchants reduce fraud risk by validating customer identity across multiple countries. Accuracy here is a compliance requirement, not a nice to have.

What I did

  • Conducted comprehensive testing across Nigeria, South Africa, and Ghana
  • Validated country-specific verification flows and data handling
  • Continued leading QA for the tool through major releases as QA Manager

Virtual Bank Accounts

API · Web
Reliable
merchant payment collection at scale
The stakes and what I didClose

Virtual Bank Accounts let merchants receive payments through dedicated account numbers. I led QA activities across functional testing, regression, and test automation for the feature.

What I did

  • Led functional and regression testing for merchant virtual accounts
  • Built automated coverage into the release cycle
  • Coordinated QA sign-off for each release with product and engineering

The meta project: building the QA organisation itself. From zero engineers and spreadsheet test cases to a 10+ person cross-functional team running an AI-driven test management practice, with Mobile Money among the latest major releases shipped under it.

What I did

  • Grew the team from zero to four, then six, then 10+ engineers across three promotions
  • Moved test management from Google Sheets to BrowserStack Test Management
  • Built the automation sub-team on Cypress and Cypress Cloud, BrowserStack, and GitHub Actions, with BrowserStack App Live for mobile testing
  • Introduced AI tooling (Claude Code, OpenAI Codex, ChatGPT, and Cursor) into QA workflows with clear human oversight

Reddit

Senior QA Engineer · Remote Contractor · Aug 2024 to Sep 2025

Reddit is one of the world's largest online communities. I led QA initiatives across three product teams, ensuring high product quality, seamless user experiences, and efficient release cycles on web, Android, and iOS.

The stakes and what I didClose

Reddit Pro is a suite of free tools that helps businesses grow their presence on Reddit, engage relevant communities, and track content performance. I owned end-to-end testing and test automation for the feature set, with a focus on the Trends tool.

What I did

  • Prepared comprehensive test plans and scripts in Zebrunner for every feature release
  • Led functional testing for Trends, plus regression and smoke tests across the full Reddit Pro suite
  • Partnered with the automation team to automate the majority of the feature set
  • Ran bug triage and worked directly with developers on issue resolution

The Profile 2.0 update gave users stronger privacy controls and richer self-expression on their profiles. Getting privacy features wrong is not an option, so QA rigour here directly protected user trust.

What I did

  • Conducted thorough QA on privacy controls and self-expression features
  • Worked with automation engineers to reach full test coverage before rollout
  • Led bug triaging and streamlined issue resolution with developers
  • Proactively identified high-priority issues before production deployment

The Posters Experience team improves how users create posts on Reddit: text, images, video, polls, links, and AMAs. I led QA for a wide range of features including Post Insights, Scheduled Posts, Rich Text Posts, Community Picker, and Post Copilot.

What I did

  • Led QA for post creation features and optimisations across all three platforms
  • Managed bug triage each sprint to keep deployments disruption free
  • Ran post-deployment testing to catch regressions early
  • Worked with automation engineers to build a comprehensive suite for new features

Seamfix

Junior QA Engineer → SQA Lead Engineer · Lagos, Nigeria · Aug 2018 to Oct 2021

Seamfix builds identity and data capture solutions for telecoms and enterprises. I grew from Junior QA Engineer to leading the QA department on national-scale projects where regulatory compliance and data integrity were the baseline, not the goal.

The SIM registration platform for MTN, one of Africa's largest telecom operators, capturing and verifying subscriber identity data for millions of users under strict regulatory requirements.

What I did

  • Led QA operations across Android and web, covering functional, usability, and security testing
  • Implemented Selenium automation for the web UI and Rest Assured suites for API endpoints
  • Ran JMeter performance testing and resolved critical bottlenecks

I am happy to walk through the test strategies, the trade-offs, and what I would do differently. That conversation is usually more useful than any case study.
