AWS serverless: Lambda, EventBridge, Step Functions, DynamoDB, SQS/SNS, Kinesis. Event-driven and distributed systems design. Node.js and TypeScript. IaC with CDK and SAM. Lambda Powertools.

AI agents and MCP in production: what actually holds up outside a demo. Also digging into Lambda MicroVMs and where sandboxed compute fits in a serverless stack.

A series on AWS Lambda MicroVMs, from running untrusted code in isolation to lifecycle hooks and best practices. And the AWS UG São Paulo meetup calendar.

Speaking at meetups and conferences, technical writing and reviews, mentoring, and consulting on serverless and event-driven architecture on AWS. Come say hi at an AWS UG São Paulo meetup.
