AI-ready portfolio for QA, systems & automation work
Mark Ezekiel Cafe
System Analyst II with a QA-first background and practical exposure to AI prompting, n8n workflow automation, Playwright testing, and digital product systems. I translate requirements into tested workflows, documented releases, and automation-ready solutions for teams that need reliability, speed, and clear execution.
QA-focused systems professional building reliable software and AI-ready automation workflows
I'm a QA Analyst and IT professional based in Cavite, Philippines with hands-on experience in payroll system validation, defect lifecycle ownership, requirements review, production release support, and cross-functional coordination. I translate business needs into clear test coverage, practical documentation, and stable user-facing systems.
My current focus expands beyond traditional QA into AI-assisted work: prompt engineering, n8n workflow automation, Playwright test automation, webhook-based process flows, Google Sheets/Gmail integrations, and automation-ready digital product systems. This gives hiring teams and clients someone who can test software, understand operations, and help turn repetitive work into structured, scalable workflows.
