Ethan M.

I help mobile teams deliver with confidence by eliminating production regressions, thanks to reliable, fast, and maintainable Maestro E2E tests, including for non-technical QAs.

Current mission — French telecom operator (Top 4)

Implementation of E2E testing infrastructure for Android and iOS applications (10M+ users each, iOS in progress): containerized Maestro runner (Docker + KVM), GitLab CI nightly + pre-release integration, support for the internal mobile team, anti-flaky standardization.

Maestro Deck — my source-available project

Author of a desktop client + cloud platform that makes Maestro accessible to testers without a command line. Stack: TypeScript, Next.js, React, Firebase, Docker, GCP. Concrete proof of my expertise on the Maestro ecosystem.

What I concretely do with my clients

- Audit and implementation of Maestro E2E testing infrastructure (Android & iOS)

- Docker containerization of runners for self-hosted CI/CD (GitLab, GitHub Actions)

- Writing and standardization of flows, anti-flaky strategies

- Training and skill development for QA and mobile dev teams

- On-site or remote training workshops

Mission format:

Available 1-2 days/week. Short missions, technical audits, occasional support, or training.

Based in Paris, travel OK up to 50 km, remote possible.

What I enjoy about this job is the moment a team stops fearing its deployments. If you are there, a 20-minute chat is often enough to see if I can help you, I'll be happy to discuss it.
