Senior🎓
Top SchoolGuillaume Bastianelli is a Staff Software Engineer with 10+ years of experience building and scaling full-stack systems, currently shaping backend architecture and technical strategy at Modjo. He specializes in serverless AWS architectures (Lambda, SQS, EventBridge, CDK) and databases (RDS, Aurora, DynamoDB), having scaled integrations to handle 1M+ calls imported per month. Comfortable across frontend and backend tech—React, Node, GraphQL—he has led migrations (TypeORM to Drizzle) and product transitions (Electron to Chrome Extension) that reduced maintenance and improved performance. He combines hands-on deployment and monitoring (Datadog) with team leadership: hiring, mentoring, and founding product squads. A former first-hire lead at CapCar, he’s adept at building stacks from scratch and turning complex pipeline needs into reliable production systems. Based near Paris, he brings an engineer’s curiosity for cloud-native patterns and pragmatic trade-offs between developer ergonomics and operational resilience.
