Congratulations Paul Santus !
The CB Spotlight 5-Timers Club welcomes its latest entrant, Paul Santus. Paul builds AI systems on AWS and shares infrastructure insights that actually teach you how to think about the problems, not just solve them. On their fictional plaque it reads:
Paul documents the full journey, not just the destination. His WebRTC piece walks through the decision between peer-to-peer and room-based architectures, shows you the local development workflow, then takes you into deployment on Bedrock AgentCore where things get real. He hits NAT gateway issues, availability zone constraints, warm pool behavior. The pattern is always the same: here's what I built, here's what broke, here's the debugging path I took. When his S3 bill spiked $659 in a week, he didn't just fix it. He enabled VPC Flow Logs, queried CloudWatch Logs Insights to find the traffic source, traced it back to warm pool image recycling, and wrote it all down so others know exactly what to watch for. That's infrastructure thinking at scale.
What makes Paul stand out is how he engages with the community as peers. Jérémie posted an S3 zipping challenge. Fitz commented with an UploadPartCopy optimization. Paul took that insight, combined it with his parallel approach, and shipped a solution 18 times faster. He documented the whole thing. He published his code. His AWS Security Agent piece uses the same rigor—walking through attack chains, showing actual exploitation steps, listing the exact code locations where fixes went. He builds in public and raises the bar.
