JSON-Java contribution
10,000+ lines contributed to the JSON.org Java library - functional, streaming, and async APIs for a 14% efficiency gain.
Overview
JSON-Java (org.json) is the reference implementation for JSON in Java - a zero-dependency library that parses JSON into Java objects and back, with converters for XML, HTTP headers, cookies, and CDL. It targets everything from Java 8 through 21 and sits in the dependency tree of a large slice of the Java ecosystem.
My contribution added over 10,000 lines introducing functional, streaming, and asynchronous APIs to a codebase that predates java.util.stream - bringing modern call patterns to the library while honoring its strict backward-compatibility and zero-dependency goals.
The new paths benchmarked a 14% efficiency improvement, and every addition ships with JUnit coverage running in the project's Maven CI pipeline.
Highlights
- 10,000+ lines contributed to the org.json reference implementation.
- Functional, streaming, and async APIs added without breaking backward compatibility.
- 14% efficiency gain on the new call paths.
- Full JUnit test coverage, verified in Maven CI.
