What I'm looking for

I seek a senior engineering role focused on payments/platforms where I can modernize systems, lead cross-functional initiatives, and deliver measurable product and business impact.

I am a Senior Software Engineer with 10+ years building scalable, resilient platforms at companies like Airbnb and Target, focused on backend systems, payments, and data-rich front-end experiences.

My work includes designing microservices, migrating legacy payment systems, and delivering dashboards and checkout features using React, Java, Python, Ruby, Kafka, and GraphQL, producing measurable improvements in engagement, conversion, and data performance.

I collaborate closely with product, analytics, finance, and compliance teams to ship user-focused, compliant solutions, modernize systems, and drive measurable business impact.
