Welcome! I’m a Senior SDET with 6+ years of experience specializing in Python test automation and AWS-based tooling. I help product teams ship with confidence by building scalable, maintainable test systems and strengthening CI/CD quality gates across Python ML and C++ application stacks. Beyond QA, I contribute to customer interviews and requirements discovery, pair-program with developers, and participate in system design to build stronger product context and make better engineering decisions. Recently, I’ve been expanding my skills in containerized web application development.

Current work

As a Senior SDET, I:

Build and validate high-speed visual inspection systems for clear aligner manufacturing. My work spans high-resolution imaging, object detection, and 3D model matching to detect manufacturing defects in uniquely shaped aligners, reliably achieving cycle times below 5 seconds per piece.

Own test automation for a Windows C++/Qt desktop application that integrates with capture hardware and 3D processing pipelines; I design and author Pytest-based automated tests for Python microservices (REST & gRPC) that power inspection workflows and use service virtualization (Wiremock) to reliably validate end-to-end behavior.

Manage Git repository rulesets (Bitbucket/GitHub) and Bamboo plans for test cycles and builds, use Docker to create reproducible test environments.

Mentor junior engineers and interns (several promoted to mid-level roles), and act as the primary onboarding contact for new hires.

Align product quality goals with customer needs through interviews and on-site visits to manufacturing facilities to ensure our software addresses real operational problems.

Hobbies

I’m into film photography for the same reason I like engineering: constraints make you deliberate. I started playing padel in Spain and love the mix of tactics and pace. And when there’s snow, alpine skiing is my favorite reset.
