About Me

Where Precision
Meets Strategy

I'm a Senior QA Engineer at Riot Games, the studio behind League of Legends, where I help ship experiences played by millions. My work lives at the intersection of meticulous testing, automation architecture, and the cultural side of quality.

Before Riot, I shaped engineering culture as a Quality Coach and Scrum Master for high-performing teams. I believe quality isn't a gate at the end of a sprint; it's a discipline woven into every line of code, every ceremony, every conversation.

Off the clock, I spent years competing at the highest levels of League of Legends. That world taught me pattern recognition, composure under pressure, and that the difference between good and excellent is almost always the process.

🎯
Quality First

Defects found in prod are a design failure, not a testing failure. I shift quality left.

⚔️
Competitive Mindset

Every sprint is a match. Analyse the replay, adapt the strategy, improve the outcome.

🛡️
Team Enablement

The best QA engineer raises the quality bar for everyone, not just their own tickets.

📊
Data Driven

Gut feel is a starting point. Metrics, coverage reports, and telemetry close the loop.

70% reduction in regression cycle time
Quality Culture

QA Maturity Programme

Designed and delivered a 12-week Quality Coaching programme across 3 engineering squads, introducing BDD, Definition of Done frameworks, and a shared quality metric dashboard.

BDD / Gherkin Agile OKRs
3 squads, 40% fewer escaped defects
API Testing

Game Services Contract Testing

Implemented consumer-driven contract testing across 12 microservices, catching integration failures pre-deploy and decoupling QA sign-off from cross-team dependencies.

Coaching

Level Up Your Team

I work with engineers, QA leads, and engineering managers who want to build quality-first cultures, sharpen their agile practice, or level up their individual craft. My approach is direct, data-driven, and built on real-world experience — not theory.

1:1 QA Career Coaching

For QA engineers who want to grow into senior or staff roles. We work on technical depth, influence, and career strategy.

Team Quality Workshop

A focused half-day or full-day session diagnosing and addressing quality bottlenecks in your engineering team's workflow.

Agile Process Review

Deep-dive into your sprint ceremonies, Definition of Done, and team agreements. Walk away with an actionable improvement plan.
