Building Lumera.
Build. Test. Prove. Ship.
I build reliable software products and the engineering systems that keep them reliable. My work sits at the intersection of mobile product engineering, test automation, mobile security, and AI-assisted development.
- Building Lumera — my primary company-building focus
- Shipping and improving products including PrepMate and Verge
- Researching secure AI-assisted mobile development at GIMPA
- Building deterministic Android & Flutter automation for CI and device-cloud execution
- PrepMate — an education product for GIMPA students
- Verge — a personal-finance product built in Accra
- Android performance tooling — practical tooling for measuring and diagnosing mobile-app performance
- Mobile automation systems — Appium, TestNG, UIAutomator2, Maestro, Genymotion and CI/CD
- Automation: Appium · TestNG · UIAutomator2 · Maestro
- Mobile: Flutter/Dart · Android/Java · Swift/SwiftUI
- CI/CD & device cloud: GitHub Actions · Azure DevOps · Genymotion
- Quality architecture: deterministic waits · stable selectors · POM · test reporting · device matrices
- Security: mobile application security · secure development · digital forensics research
- Turn flaky UI suites into reliable engineering signal
- Prefer stable interfaces and deterministic tests over fragile shortcuts
- Treat quality, security and observability as product concerns—not release-day checks
- Build small, useful systems, measure them, and improve them from evidence
Signal over noise · Small surface area · Repeatable proofs · Reliable systems · If it isn’t deterministic, it isn’t done.
