Robin Duda @codingchili

Software developer and security enthusiast with an interest in networks. Working on open source projects with friendly licensing in my spare time, listed here are a few of the more useful projects. Some of which build on my own frameworks, such as the backend framework 'chili-core' or 'static-mina' which is a static site generator. I love to work with new technology and awesome libraries.

Prefer reactive microservices, Docker and NoSQL, disinterested in application servers and object relational mappers :)

Mostly web development with responsive/progressive web applications that works well on mobile. A bit of desktop and native Android.


These are my core skills, always looking to improve. Learning a bit of Kotlin and Vyper on the side, doing networking and security labs, reading and trying new things!

Libraries & Frameworks

These are the libraries & frameworks I frequently use and enjoy. I do a bit of Java EE as well, with JAX-RS/JAX-WS and Wicket on the frontend. They're not on the list because I'm much more productive and enjoy working more with the given alternatives.

Please contact me if you have any questions, feedback, feature requests.. or anything else really.
