Summary
👤
SeniorMat Henshall is a hands-on Principal Engineer and technical leader based in Berkeley with 20+ years of engineering and product experience and eight years focused on modern cloud-native startups. He specializes in event-driven, serverless GraphQL architectures and has repeatedly designed and shipped domain-driven microservices on AWS and GCP (API Gateway, Lambda, SQS, Pub/Sub, Kafka, Postgres/MySQL) for healthtech and fintech products. As a fractional CTO and consultant he bridges product strategy and execution—piloting headless FHIR EHR integrations, building AI agent PoCs, and converting complex auth and workflow systems into maintainable GraphQL/Prisma stacks. Known for mentoring distributed teams and improving deployment and incident practices, he combines founder-level product judgment with deep implementation skills and a taste for pragmatic, incremental architecture. An oft-overlooked strength is his history of shipping hardware-plus-cloud products and IoT platforms early in his career, which gives him a systems-minded perspective on reliability and integration.
