Senior full-stack software engineer delivering scalable web and mobile systems.
United StatesI am a senior full-stack engineer with 13 years building web and mobile products across travel, e-commerce, aerospace & transportation, and healthcare. I design and implement scalable backend and frontend systems, drive cloud-native infrastructure work, and deliver measurable performance and reliability improvements.
At recent roles I engineered services to support 10,000+ concurrent users, cut database query times by 60%, reduced page load from 13s to 3s, migrated platforms to Kubernetes, and built CI/CD pipelines that slashed deployment time by 70%. I work effectively in agile teams, prioritize security and accessibility, and focus on shipping high-quality, user-centered software.
