Summary
👤
Senior🎓
Top SchoolMark Sims is a senior software engineering consultant with 11 years of focused experience in full-stack and cloud-native architectures, and a remote-working track record dating back to 2005. He combines hands-on delivery—Node.js, TypeScript, React, Serverless and AWS—with leadership in Agile practices, TDD/BDD, CI/CD and trunk-based development to help teams ship resilient, observable systems. Mark has led major transformations from monoliths to microservices and driven high-availability migrations while shaping product backlogs and fostering upfront collaboration over post-hoc reviews. At YLD he’s helping scale open-science platforms that enable global research collaboration, and previously built core data and search services for financial products using event-driven patterns and ElasticSearch. Comfortable as both architect and coach, he blends pragmatic engineering with a history of startup and consultancy impact across finance, media and research. He holds a master’s in computer science from Bristol and brings a systems-thinking approach rooted in earlier civil engineering training.
