What I'm looking for

I am looking for a role that fosters innovation, offers growth opportunities, and values team collaboration.

With over nine years of experience as a Staff Software Engineer, I have developed a strong passion for innovation and entrepreneurship. My journey has taken me through various roles where I specialized in distributed full-stack product development. At PayPal, I worked on the Dispute Customer Experience Team, where I designed and developed a new micro-service for disputes-related APIs, significantly reducing customer support contact by 29.6% through efficient conversational flow design.

My commitment to lifelong learning drives me to continuously advance my skills and knowledge. I have mentored junior developers and automated release processes, showcasing my dedication to team growth and efficiency. My technical expertise spans a wide range of programming languages and technologies, including React, Java, ExpressJS, NodeJS, and Kubernetes. I aspire to advance to the role of Software Architect, aiming to be an inspirational leader in the field.
