Top SchoolCharles Simms is a Senior Software Engineer in the Bay Area with a decade of experience building resilient web and integration systems across fintech and healthcare. He’s shipped customer-facing React/GraphQL dashboards and led platform improvements at Marqeta, then designed high-throughput FHIR integration infrastructure at Vital using AWS Lambda, SQS, DynamoDB and TypeScript. At Vital he scaled a system from zero to tens of thousands of API requests and SQS messages per hour and executed a zero-loss migration from Kinesis to SQS—evidence of his pragmatic approach to reliability and data consistency. A strong communicator and former instructor, he pairs hands-on engineering with mentoring and a knack for translating complex systems into teachable parts. Raised in the East Bay with a BA in Mathematics and a background ranging from bicycle maintenance to tutoring, he brings curiosity and practical problem-solving to every technical challenge.
