What I'm looking for

I seek a cloud-focused engineering role where I can lead technical initiatives, mentor engineers, and deliver scalable, high-availability systems within an agile team.

I am a Senior Software Engineer with 9+ years building scalable web applications and cloud-native systems across startups and large enterprises. I focus on designing reliable microservices, event-driven architectures, and performant front-end experiences.

At Amazon I led end-to-end development for a managed data integration service, engineering backend microservices, serverless processing, and developer SDKs while improving throughput and latency. I have built user-facing dashboards with React and TypeScript, applying SSR and performance optimizations.

Previously I contributed full-stack features for payment and POS workflows at Square and developed payroll and workforce microservices at Vendorpass, working with event-driven systems and real-time dashboards. I emphasize testing, automation, and observability to maintain high availability.

I enjoy mentoring engineers, championing Agile practices, and delivering customer-critical features on schedule. I seek roles where I can apply cloud-native patterns, lead technical initiatives, and drive measurable product outcomes.
