• AWS What's New Aggregator

  Real-time aggregator for the AWS "What's New" feed. A Lambda polls the RSS every 30 minutes, auto-categorizes each update into 17+ service categories, and resolves official AWS service names. The React front end adds server-side search, multi-category filtering, trend charts, compact/normal views, and HTML/Markdown export. Fully serverless — CDK-deployed Lambda, DynamoDB, API Gateway, and CloudFront — for about $1.67/month.

• Personal Portfolio Site

  j0e.us-Portfolio is an open-source, serverless personal portfolio template built with Next.js 15, React 19, and TypeScript, designed to be forked and redeployed under any custom domain and AWS account. The static site is served globally via CloudFront in front of private S3 buckets, while a small API Gateway + Lambda + DynamoDB backend powers an authenticated admin console.

• Wag Watch

  Mobile-first web app for senior dog care, built for our 17-year-old hound Daisy when "how has she been?" kept coming up as a feeling instead of data. Multi-caregiver event logging (medications, mobility, accidents, behavior), trend charts and calendar heatmaps to surface patterns, and an Amazon Bedrock chat that answers questions grounded in the actual history. Fully serverless on AWS, single-command deploy, ~$1/month.

• Guidelines for protecting your AWS account while using programmatic access

  AWS Security BlogFeb 6, 2019

  One of the most important things you can do as a customer to ensure the security of your resources is to maintain careful control over who has access to them. This is especially true if any of your AWS users have programmatic access. Programmatic access allows you to invoke actions on your AWS resources either through an application that you write or through a third-party tool. You use an access key ID and a secret access key to sign your requests for authorization to AWS. Programmatic access can be quite powerful, so implementing best practices to protect access key IDs and secret access keys is important in order to prevent accidental or malicious account activity. In this post, I’ll highlight some general guidelines to help you protect your account, as well as some of the options you have when you need to provide programmatic access to your AWS resources.
