About

Hi, I'm Will.

I've worked with cloud and distributed systems for years, today as Staff Engineer at Serverless Guru, AWS Community Builder (and AWS Certified) and one of the leaders of AWS User Group São Paulo. I specialize in serverless, AWS and event-driven architectures, and I'm also deep into AI agents and how they're changing the way we build software.

At its core, my job is one thing: take a business problem and turn it into architecture that scales, survives failure and doesn't blow the budget. Technology is the means. What lasts is the impact.

What you'll find here

Architecture content in practice, the way I like it: with code, real examples and the decisions behind them. No theory-only posts. The topics revolve around:

• Serverless and event-driven on AWS (Lambda, EventBridge, Step Functions, DynamoDB and friends)
• Resilience, cost and the architecture decisions that actually matter
• AI agents, MCP and the new way of building software with AI
• Best practices and tooling (I'm a fan of Lambda Powertools) and lessons from production

I write short, direct and honest. If a post has no code or a concrete decision, it didn't come from here.

Let's talk

Find me on LinkedIn, GitHub, X and Instagram. Comment on the posts, send your questions, tell me how your architecture held up in the last outage. Things grow through exchange.

BUILD. SCALE. REPEAT.
