I’m a Senior Software Engineer who builds real-time, scalable systems that feel fast and reliable for end users. At Gusto, DoorDash, and Nike, I’ve focused on modern web experiences, event-driven backends, and production-ready architecture—turning complex workflows into smooth customer outcomes.

At Gusto, I led development of the Run Payroll Modernization platform, improving interaction speed and reducing page load time by 28%. I engineered real-time UI updates using GraphQL subscriptions/WebSockets and delivered a scalable React component architecture and design system (React, Tailwind CSS, Storybook) that accelerated feature delivery by 25%.

I also owned high-throughput, fault-tolerant payment and background processing pipelines—architecting ACH processing with Kafka + Sidekiq + Redis (8x throughput) and building async orchestration to process 100M+ jobs per day with retry and idempotency guarantees. To raise product intelligence, I integrated an LLM-powered assistant (RAG), reducing support tickets by 25%, and deployed services on AWS EKS with autoscaling to cut infrastructure costs by 20%.

Previously at DoorDash, I maintained a real-time marketplace using Node.js, Java (Spring Boot), and Kafka—supporting millions of orders with sub-second latency, optimizing dispatch/routing (25% delivery efficiency), and improving observability with Datadog and Prometheus (35% faster incident resolution). Earlier at Nike, I delivered global-scale apps with React/Next.js and backend APIs (Java Spring Boot, Node.js), building event-driven microservices and CI/CD pipelines (Jenkins, Docker, AWS CodePipeline) to support multiple environments.
