My Philosophy

I believe in making AI accessible to everyone. That's why I focus on offline-first solutionsthat don't require expensive cloud services or internet connectivity. Privacy, control, and openness are at the core of everything I build.

Through XandAI, I'm committed to sharing knowledge, building practical tools, and fostering a community of developers who want to harness the power of AI without compromising on privacy or spending a fortune.

Let's Connect

I'm always excited to collaborate on open-source projects, discuss AI and software architecture, or just chat about technology.
