Preserved floating-point precision in MPS model exports and added a regression test, so exported values retain the precision of the original model. Merged 19 October 2026.

Microsoft Java Debug · #648 · Merged ↗

Corrected the event order during hot code replacement so the debugger UI consistently reflects a suspended thread. Merged 2 November 2026.

Java is my first choice. Building something useful is the mission.

I build backend systems, web apps, and practical tools that turn everyday friction into working software. Sometimes that means a clipboard that connects devices. Sometimes it means digging into sockets, persistence, and what happens underneath an API.

Moon Knight brings the atmosphere; the code tells my story. I like projects where I can follow a request from the interface to the database, understand the moving parts, and write tests for the details that are easy to miss.

• My main language: Java, especially for backend services and exploring how systems work.
• On the web: TypeScript and JavaScript for interfaces, browser tools, and full-stack apps.
• What I'm working on: practical Java projects and open-source fixes with clear reproduction steps and regression tests.

One developer behind the mask. Plenty of problems worth solving.

Four projects. Four different reasons to open the editor.

What does a key-value server actually do after you hit Enter?

An educational Java 21 server implementing a useful subset of Redis over RESP2: expiring keys, concurrent clients, command validation, and optional append-only recovery. Built to explore the machinery, with a deliberately limited scope.

A note on one device. Ready on the next.

A text-only clipboard for sharing notes and links through private URLs. Includes live WebSocket updates, H2 persistence, and 24-hour expiry, served from a single Spring Boot app.

Applications, interviews, and follow-ups deserve more than scattered notes.

A job-application tracker with a dashboard, stage board, filters, and follow-up reminders. One Spring Boot application connects the browser interface, REST API, and database.

Save the useful link before it disappears into tab number forty.

A bookmark library with collections, tags, notes, and search, plus a Chrome/Edge extension for saving the current tab. Built with Next.js and a JSON-backed library for local or single-server use.

Building my own projects is one part of the story. Contributing fixes, tests, and documentation to other projects is another.
