Senior🎓
Top SchoolMichael Celani is a middleware engineer with a decade of experience building cloud-native systems, APIs, and high-volume data pipelines primarily in C#/.NET, TypeScript, React, and Azure. He has designed microservice architectures and pioneered Kubernetes patterns at Relativity that remain in production, and he built the real-time pharmacy switching and billing audit systems at EVERSANA that cut operating costs by integrating multiple vendors. Early work at Epic sharpened his expertise in healthcare interoperability (CCDA, HL7) and reliable data recovery, while his side project Recommander demonstrates applied ML and production-grade deployment—serving 1,000 users daily and recommending over 200,000 decks. A practical engineer who enjoys clean code and scalable systems, he also contributes to open-source tooling like more-itertools, improving iterable utilities and documentation.
