I build the safety net between code and production. Right now I'm pioneering the first formal QA practice at Wilson Works Trading Inc. — architecting Playwright frameworks, leveraging AI for test healing, and pushing manual workflows into fully automated CI/CD pipelines.

The person behind the test cases.

John Michael M. Dionisio
jm.dionisio

I'm a Computer Science graduate from the University of Santo Tomas who started his career in manual QA at Pao Ying Food Inc. — authoring test cases and end-user manuals for a fingerprint attendance system.

A full-stack internship at Shoppable Business under direct CTO mentorship sharpened my engineering instincts, and today I'm the Lead QA Specialist at Wilson Works Trading Inc., pioneering the company's first formal QA practice and Playwright automation framework from the ground up.

I'm on the path to becoming a full SDET — bridging test automation, backend debugging across AWS & MongoDB, and AI-assisted tooling. I work best where engineering, quality, and product collide.

Quality Assurance

From manual test plans for the AFAPS fingerprint system at Pao Ying Food, to architecting the entire QA lifecycle at Wilson Works — I've owned quality at every scale.

SDET Mindset

End-to-end Playwright frameworks with AI-assisted test generation and self-healing scripts. Postman + Swagger for API contracts. Sentry, Jam.dev, and Bull Dashboard for observability.

Full-Stack Builder

React, Node.js, Java, Python — mentored by a CTO at Shoppable Business. I ship backend fixes, optimize developer workflows, and read code as fluently as I break it.
