What I'm looking for

I am looking for a role that offers opportunities for leadership, innovation, and continuous learning in a collaborative environment.

I am a self-motivated professional with extensive experience in Information Technology, particularly in Quality Assurance (QA) and leadership roles. As a QA Manager at Carta, I have successfully led manual and automation QA efforts across various services, ensuring the delivery of defect-free software for financial applications. My deep understanding of advanced testing methodologies and the software development life cycle has enabled me to drive quality initiatives and improve production processes significantly.

Throughout my career, I have consistently demonstrated my ability to mentor and develop teams, fostering a culture of growth and continuous improvement. My strategic approach has resulted in a 50% reduction in production issues within eight months of taking on the QA Manager role. I am passionate about advocating for quality at all levels of the organization and integrating QA into every stage of the development lifecycle.
