Professional summary

QA leader with 14+ years building quality engineering functions from scratch across AI tooling, AR/fashion, fitness tech, and banking. Moves fast without breaking things: shipped daily releases, 4x release cadence, and 80% customer satisfaction gains by turning QA from a gatekeeper into a product accelerator. Leads teams, writes automation, owns production incidents, and isn't afraid to throw out the old playbook when the problem demands it. Currently hands-on with AI-assisted testing, using agents, MCP servers, and BDD frameworks to make quality scale as the team grows. ISTQB CTAL-TAE certified.

Experience

Zencoder

May 2025 – Present · Contract · Porto, Portugal (Remote)
Position: QA Team Lead

I lead the QA team that solved this by moving from traditional test-after-dev to a model where developers write their own tests with agent assistance.
