Posts on Java, Spring Boot, IntelliJ plugins and developer tools

Talking to SAP Commerce Through Claude

hac-mcp is an MCP server that exposes SAP Commerce's Hybris Administration Console to Claude with per-environment permissions. It runs FlexibleSearch, ImpEx, Groovy, and CronJobs from a conversation.

Building a Better JSON Viewer from Scratch

I built a JSON viewer as a PWA to see if a brand-new site could climb Google's rankings. Edit: it couldn't.

Visualizing Method Calls in IntelliJ IDEA

CallGraph is an IntelliJ plugin I built so I could stop tracing method relationships in my head. Place your cursor on any method and get an interactive graph of its callers.

Managing Bitbucket Pull Requests Through Claude

bitbucket-mcp is an MCP server that gives Claude programmatic access to Bitbucket Cloud. List, create, review, and merge pull requests from a conversation, with protected branches keeping sensitive targets off limits.

Enhancing Kibana Logs with Color

A Tampermonkey userscript that colors Kibana log rows by level, so an ERROR stands out from the DEBUG and INFO rows around it.
