What I'm looking for

I seek a product-focused role where I can own quality strategy, grow automation coverage, mentor teams, and collaborate with stakeholders in an agile environment.

I am a Lead QA Engineer with experience building QA strategy, automation, and product vision across start-ups and enterprise teams, bringing a joint effort between quality and product development, by understanding the business needs to define a quality strategy and metrics to show the outcome and impact of each development to the users.

I have defined test strategy and policy from scratch, implemented QA academies to mentor junior testers, and automated hundreds of API and UI scenarios to improve release quality and speed.

At Critical Techworks, I co-created product vision and artifacts, drafted epics and user stories, and introduced QA dashboards that reduced defect detection time by 20% while increasing automation coverage by 45%.

I hold multiple certifications, including CSM, PSPO I, ISTQB Foundation, and Advanced levels for Automation and Test Management, and Azure Fundamentals.

Prioritize clear stakeholder communication, continuous improvement, and practical leadership in agile environments.
