At Cambium Networks, I designed centralized SSO across three services and organization-level subscription APIs. I also integrated Claude Vision API for AI-powered floorplan wall detection, optimizing API usage with LRU caching and token optimization.
I led spec-driven development adoption while modernizing a legacy JSP/Spring application into Spring Boot APIs and Dockerized AWS deployments. I also led a four-engineer team in consolidating the product ecosystem by migrating 65K access points into a unified network, contributing to projected cost savings.
At OneTrust, I contributed backend capabilities for an ESG platform designed to handle about 1,000 requests per second. I designed database schema and audit logging for regulatory traceability, and engineered PySpark ETL on Azure Data Lake for emissions data.
At ACI Worldwide, I developed a reusable Java/Spring middleware framework and a distributed payment-settlement platform stress-tested to more than 10 million transactions per day. I also built Replay, an AI-powered workflow memory system using RAG, embeddings, and semantic search.
