Senior🎓
Top SchoolRex Sheridan is a seasoned engineering leader and SRE manager with 20+ years designing and operating large-scale distributed systems across fintech, automotive fleets, and real-time clearing platforms. He combines hands-on architecture skills with people leadership—building resilient authorization layers, modernizing stacks to cloud-native patterns, and improving operational metrics through CI/CD and progressive rollouts. As a founder/CTO he has built AI-enabled production systems (RAG pipelines, LLM agents, vector search) that reduce support load and automate log classification to cut false-positive paging. Rex is comfortable translating ambiguous business problems into pragmatic technical solutions, running hybrid onshore/offshore teams, and advising startups as a mentor and angel investor. Based in Marietta, GA, he’s equally fluent in deep systems thinking (high-throughput, low-latency financial systems) and pragmatic product engineering that drives measurable business outcomes.
