Summary
👤
Senior🎓
Top SchoolPablo Calvo is a Senior Software Development Engineer in Test with 11 years of experience building resilient test automation and backend tooling across fintech, retail energy, and e‑commerce. He combines deep SDET expertise with hands-on Go development—authoring core test libraries, a centralized test-service, and an internal CLI to streamline test data and observability (Prometheus/Grafana). As the first SDET at Zero Hash he set testing standards and built webhook and load-testing solutions that validate end-to-end customer journeys; previously he led QA for Shell Retail Energy and contributed to WebdriverIO’s documentation and DevTools support. Comfortable across stacks (Go, Python, TypeScript, Playwright, Selenium), he also teaches QA fundamentals and has a track record of turning ad-hoc testing needs into production-grade frameworks. Notably, he blends leadership and individual contributor roles, hiring and mentoring teams while still shipping low-level automation and tooling.
