Hi! My name's Paulo and I'm the author and maintainer of Logtalk, a declarative object-oriented logic programming language that extends and leverages the Prolog language.
Your kind donations will help sustain the development of Logtalk and its ecosystem. My ultimate goal is to be able to work on Logtalk full time.
I'm also a long time Prolog developer making regular contributions to the community. I'm a regular presence in public forums, sharing my experience and helping new users. I worked on Prolog standardization, significantly advancing Core, DCGs, and Threads proposals. I maintain a comprehensive standards compliance test suite. I have submitted (and continue to submit) thousands of bug reports and patches to improve Prolog systems and open source Prolog applications. I make available via Logtalk portable and essential developer tools that are also usable from Prolog. I develop and maintain actions and workflows for use with Logtalk and Prolog repos. I also implemented and contribute Logtalk and Prolog support for several text editors and syntax highlighters.
Thanks for your support!
