Vetted Web Developers in California

“Engineering leader managing two 6-person teams across internal tools and 14+ public brand websites, while staying hands-on in architecture and system design. Particularly interesting for teams exploring AI-assisted software delivery: they implemented a customizable multi-agent BMad workflow with human review gates across PM, architecture, development, QA, and DevOps.”

“Backend engineer with experience at Roche and Jarsy focused on API and data-layer performance. Re-architected slow generalized endpoints into more efficient APIs (30% faster lookups) and led a schema refactor/migration with feature-flag rollout, dual writes, rollback scripts, and automated integrity checks; also addressed pipeline duplicate-entry issues via deduplication.”

“Backend engineer with TaskRabbit experience building and operating payment/booking services in Python/Django on AWS (ECS + Lambda) with Kafka/SQS eventing. Demonstrates strong production reliability and incident ownership in high-stakes payment flows (idempotency, strict timeouts, retries, monitoring/alerting) plus data/ETL work in AWS Glue and measurable SQL performance wins.”
