I'm Defrim, a software engineer in Pristina, Kosovo. My work spans Java and Spring Boot, native macOS apps, and browser-based developer tools.
Here are a few things I've built.
Your databases. A native Mac app.
A macOS SQL client for PostgreSQL and Cloudflare D1. Workspaces, a native query editor, Keychain-backed credentials, and a built-in MCP server that gives AI agents controlled access to saved connections.

Get the architecture out of your head.
A browser-based canvas for mapping microservices. Drag services, connect them with protocol-labelled edges, and annotate the details. Diagrams stay in your browser's local storage; no account required.

My Java projects explore the building blocks behind larger systems:
- Albanoi — a Java library of helpful building blocks for domain-driven design.
- Regula — a simple Java rule engine.
- Active Object example — an implementation of the concurrency pattern in Java.
