Hey there! 👋

I'm Sebastián Clavijo Suero

Staff QA Engineer/SDET • Test Automation Expert • Open Source Contributor

I'm that QA engineer/SDET who turns bugs into features and creates Cypress and Playwright plugins that actually make sense. When I'm not breaking things professionally, I'm probably writing about it.

Holistic approach

System-thinking QA that traces seams from design reviews, planning cadences, usability research, automation frameworks, and release playbooks so the entire lifecycle stays observable and accountable.

Results driven

Define success metrics before automation starts, wire suites to those signals, and retire tests once they stop preventing real-world regressions.

Curious & quirky

Prototype offbeat ideas, name labs after cult films, and publish the takeaways as plugins or articles so teams stay playful while chasing reliability.

Origins & Practice

More than two decades across product, support, and engineering shaped this user-centric, positively skeptical, results-driven QA leader.

I’ve worn almost every hat: analyst, developer, SW engineer, consultant, technical product lead, product manager,and now Staff QA/SDET. Every role tuned another sense, strategic empathy, system-thinking, system-level debugging, and a strong bias for measurable outcomes.

QA became the place where user interviews, service metrics, and code-level debugging intersect. So every experiment starts with real customer context and ends with measurable impact.

"Optimism is allowed. Blind faith is not. I choose positive skepticism every single sprint."

The connector advantage

What sets me apart is that I’ve lived each stop in the software lifecycle: requirements, design, build, release, and support. I know how a product must feel for users, how it has to behave for engineering, and how it needs to perform for the business. I bring that full-cycle empathy into QA so teams ship software that not only works but stays loved in production.

Signature Moves

Automation Architect

Designing frameworks that survive reorganizations, flaky APIs, and vendor musical chairs.

Curiosity Drills

Scenario labs where engineers, designers, and support rehearse unexpected user journeys before they become incidents.

Community Amplifier

Blog posts, and plugins that turn hard lessons into shared shortcuts.
