Summary
👤
Senior🎓
Top SchoolKalleb Santos is a founder and veteran backend engineer with nine years building serverless, cloud-native systems for FinTech and HealthTech clients, specializing in Node.js, TypeScript and AWS Lambda. He moved from hands-on development to chapter leadership and now runs Serverless Code, where he designs IA-driven automations and serverless architectures that cut operational costs and manual work. His track record includes orchestrating 1,000+ Lambdas with Step Functions, low-latency multi-tenant API caching at scale, and integrations across regulated financial and healthcare environments. He mentors teams, sets architectural standards, and focuses on pragmatic simplicity—solving the right problem rather than producing elegant code for its own sake. Based in São Paulo, he combines a mathematician’s rigor with a hacker’s curiosity and a low tolerance for needless bureaucracy.
