Senior QA Automation Engineer · QAOps · 5+ years

I build quality into the delivery pipeline with Playwright and Cypress frameworks, CI quality gates, and performance and security testing. That has cut regression cycles by 40% and production hotfixes by about 60% on high-traffic iGaming platforms.

About

QA strategy aligned with business goals.

I'm a results-driven QA Automation Engineer who builds quality into teams rather than bolting it on at the end, across iGaming, fintech, and SaaS platforms. I focus on making releases safe, predictable, fast, and confident, by combining smart test design, automation, and observability.

My work has consistently delivered near-zero critical production defects across high-traffic platforms supporting large user bases.

Collaboration

Shipping quality, together.

Quality is a team sport. Here I am pairing with senior developers Donald Kengue and Kum Jude Tem, reviewing automation strategy and triaging defects in real time. Close partnership with engineering is how I keep production stable and releases predictable.

Senior QA Automation Engineer

Feb 2023 - Jul 2026

Blue Window Ltd · iGaming · Douala, Cameroon

  • ▸Built a Playwright + TypeScript framework (Page Object Model, parallel execution, Allure reporting). Regression cycle time dropped 40% and the team moved to daily releases.
  • ▸Integrated E2E, API, and accessibility suites into GitHub Actions with quality gates that block deployments on critical failures, cutting production hotfixes by roughly 60% over two quarters.
  • ▸Containerized the suite with Docker and ran parallel browser tests on a self-hosted Kubernetes grid, scaling from 4 to 30+ concurrent workers and turning multi-hour runs into minutes.
  • ▸Owned load testing with k6 and JMeter across login, deposit, and live gameplay flows, validating stability at 10,000+ concurrent users.
  • ▸Built Splunk dashboards over Cloudflare logs to catch traffic anomalies, bot patterns, and latency spikes that synthetic monitoring missed.
  • ▸Ran OWASP-aligned security tests and WCAG 2.1 accessibility audits supporting regulatory compliance across multiple jurisdictions.
  • ▸Partnered with Engineering, DevOps, and Product to shift quality checks earlier in the sprint and define clear Definition of Done criteria.

QA Automation Engineer

May 2019 - Jan 2023

Pro-Tech Alliance · Remote

  • ▸Built a Cypress framework from scratch covering 300+ critical user flows, taking automated regression coverage from zero to 85%.
  • ▸Configured Jenkins and GitHub Actions pipelines to run the full suite on every pull request for fast pre-merge feedback.
  • ▸Cut test flakiness from roughly 18% to under 3% through better locator strategy, custom commands, and smarter retry logic.
  • ▸Turned business requirements into structured test plans and risk-based strategies with Product and Engineering.

QA Tester

Nov 2020 - Jul 2021

Seven Advanced Academy · Cameroon

  • ▸Created a bilingual (English/French) Selenium WebDriver + TestNG framework, cutting manual test cycle time by 30%.
  • ▸Grew test coverage by 25% by pairing manual testing with targeted automation on the highest-risk regression areas.
  • ▸Mentored junior testers on Selenium, TestNG, and automation patterns so the team could own automation themselves.
  • ▸Managed the defect lifecycle in Jira with a 98% on-time resolution rate.

Software Test Analyst

Sep 2018 - Jan 2020

IWOMI Technologies Ltd · Douala, Cameroon

  • ▸Defined and ran test strategies across 10+ enterprise web applications, keeping critical incidents out of production.
  • ▸Introduced Cypress as the team's first JavaScript automation tool, reducing regression time by 40%.
  • ▸Led UAT sessions with business stakeholders and delivered on-time releases with zero critical defects.
  • ▸Trained QA team members on automation fundamentals and scripting.

Projects

Tools I've built for QA & web teams.

Independently designed, built, and deployed, from architecture to production.

security_project

SiteShield

Most teams do security testing by booking a consultant, waiting weeks, and getting a report that's out of date before anyone reads it. SiteShield lets any QA engineer or developer run an OWASP-aligned audit on any website in minutes, without specialist knowledge.

Each scan scores a site 0–100 across 11 categories (security headers, TLS, DNS/email, CORS, cookies, exposed files and more) with a letter grade and a PASS / REVIEW / FAIL verdict. Teams can bulk-audit up to 100 sites via CSV, track a fleet dashboard with score trends, schedule re-scans with regression alerts by webhook or email, and export PDF or JSON reports.

VPerformance

A full-stack platform for running batched Lighthouse tests against any URL, surfacing Core Web Vitals (LCP, CLS, INP, TTFB, Speed Index) across desktop and mobile in one place.

Side-by-side comparisons across multiple sites with device-specific breakdowns and prioritized optimization suggestions turn Lighthouse numbers into something a team can act on.

UI Design Validator

Compares Figma design specs against live web implementations and flags pixel-level deviations, closing one of the most common and expensive gaps in product QA.

Pulls design tokens through the Figma API, captures the implementation with a headless browser, and applies configurable tolerances so teams decide what counts as a real regression.
