About me

I build quality into
the process, not after it.

I’m João Pedro Luz, a QA Engineer based in Belo Horizonte, Brazil. I specialise in automation architecture and test strategy for teams shipping at speed — from CI/CD pipeline design to security and performance coverage. I work best in technically demanding environments where quality needs to be built into the process, not bolted on at the end.

stage: approach

I specialise in crafting comprehensive test strategies that go beyond functional coverage — integrating performance, accessibility, security, and visual testing directly into CI/CD pipelines. I work closely with Product Owners, Developers, and Designers to ensure quality is embedded early and consistently, not bolted on at the end.

I’m passionate about cybersecurity and regularly support teams in identifying vulnerabilities. Beyond the technical side, I enjoy mentoring junior QAs and contributing to team growth through clear documentation and collaborative planning. Whether optimising performance or implementing security testing, I’m driven by delivering impactful, user-focused solutions.

What I value

  • Decisions over tools

    The right tool fits the team, the scale, and the problem — not just the most popular option.

  • Security as a first class concern

    Vulnerabilities caught in CI are far cheaper than ones found in production.

  • Speed through confidence

    Solid automation is what makes fast delivery and high quality possible at the same time.

  • Mentorship and team growth

    The best QA outcome is a team where everyone owns quality, not just the QA engineer.
