Personal Projects
H-tchen Mail — A serverless daily watchlist monitor that emails me only when a stock forms a meaningful Heikin Ashi pattern. Built on AWS Lambda, Java 25, Micronaut, DynamoDB, and Bedrock. I built this deliberately as a vibe-coding experiment — using Claude as a design and implementation partner throughout — to understand in practice where AI-assisted development works well and where it breaks down. The four-part series on the blog documents the design conversation, the workflow that emerged, and the production failures the spec couldn’t prevent.
functional-validator — A lightweight Java validation library built around a fluent builder API: composable predicates, lambda-defined error messages, nested object support, and an Optional-returning result. A half-afternoon prototype exploring whether bean validation boilerplate can be replaced with something more readable.
