At Sysquare Technologies, I build backend systems for products including Auto Knowledge, Ellis Island Honor Society, My Auctions, and the PGA MBS Golf Leaderboard. I engineered a RAG pipeline with FastEmbed and Qdrant, upgraded Apache Lucene from v5 to v10 with zero downtime, and reduced an 8M+ record data-sanity job from three hours to under two minutes.
I work primarily with Java, Spring Boot, SQL, search infrastructure, caching, and event-driven systems. I've improved API response times by 72%, built real-time leaderboard updates with Server-Sent Events, and created scalable media processing pipelines using AWS S3, Lambda, and CloudFront.
I also build shared backend libraries, modernize legacy systems with automation tooling, and mentor incoming Java engineering cohorts.
