Senior SDET · ML quality · EU remote
Most SDETs test the app. I've shipped the app.
Around 9 years building test automation in Python, TypeScript and C#, now extending it to ML and data pipelines.
Open to senior QA/SDET and ML-quality roles, EU-remote. Select contract engagements considered.
Test infrastructure, API checks, data validation, and release evidence designed as one system.

01 / Featured projects
Resume-backed case studies that show the delivery pattern, impact, and technical surface without relying on private code.
Playwright and Selenium suites for React/TypeScript device registration, authentication, and multi-locale flows, backed by Jenkins quality gates.
Can turn complex product journeys into maintainable release checks while using AI as a practical accelerator.
Python, Java, Postman/Newman, MySQL, and Pandas checks for ingestion, data integrity, access control, and payment-data APIs.
Can validate APIs, data paths, business rules, and CI evidence in one coherent quality system.
Playwright, Cypress, Python, Postman, and Requests frameworks across AWS and Azure services, with test execution and coverage improvements.
Can build SDET infrastructure from scratch and connect it to cloud-backed delivery workflows.
02 / Featured code demos
Repo cards separate public source, private-source case studies, local artifacts, and planned demos.
high priority
Offline model/API evaluation harness with versioned cases, provider boundary, deterministic checks, readiness thresholds, and JSON evidence.
MLOps quality gate design, testable model behavior, structured output validation, and CI-friendly reporting.
high priority
Static Next.js portfolio deployed behind Nginx Proxy Manager with HTTPS, route-level metadata, sitemap, and resume-backed case studies.

06 / Work style
Treats quality as a system, not a late-stage checklist.
Builds the framework, wires CI, and makes failures legible.
Turns manual regression paths into maintainable coverage.
Hands over code, docs, and the reasoning behind the tradeoffs.
07 / About
Physics background from Hamilton College, around 9 years in QA and test engineering across Canada, the United States, and Portugal, and a working habit of shipping side projects. The current direction is quality engineering for ML and data systems: testable behavior, validated data paths, and release evidence a team can trust.
