About CodeWriter bv

CodeWriter, founded in 2022, originated out of the work done by Frank Delporte as webtechie.be for various open-source and commercial projects. As a Java Champion, Frank Delporte loves to write and talk about Java and JavaFX and create projects running on the Java Virtual Machine (JVM), including code written with Kotlin.

Mission

At CodeWriter, we love to develop elegant, efficient software solutions that help businesses and developers work smarter. We combine deep expertise in Java technologies with a passion for clean code and clear learning resources and documentation.

Expertise

With over 30 years of experience in Java development, CodeWriter specializes in:

• Enterprise Java applications, like the HMI training application for train drivers.
• JavaFX desktop user interface solutions, as shown in MelodyMatrix and our open-source libraries.
• Embedded Java for IoT devices, described in the book Java Programming for Raspberry Pi.
• Cross-platform development with Kotlin.
• Performance optimization for JVM applications.
• Writing clear and maintainable documentation.
• AI strategy and tooling: defining where AI helps, and where it does not.

AI: Useful, But Not Everywhere

We help companies define how to use AI, and build tools that put it to work in a way people actually want to use. Just as important, we help them avoid the overuse of AI: a lot of work is still done best by a good old-fashioned script that runs in milliseconds, costs no tokens, and returns the same answer every time. Knowing which is which saves money and keeps results predictable. Read more about our AI services.

Approach

We believe great software stems from three core principles:

• Technical excellence that prioritizes maintainability and performance.
• Clear communication throughout the development process.
• Knowledge sharing that elevates the entire Java community.

Community Involvement

CodeWriter is deeply committed to the Java ecosystem through Frank's role as a Java Champion:

• Open-source Java projects: Pi4J, Lottie4J, MelodyMatrix, Sheetmusic4J, and DMX512.
