About Me
A brief introduction to who I am and what I do
~/about/README.md
I've been building software since 2005 and working professionally since 2012. My focus is on AI-oriented development, creating solutions that leverage modern AI capabilities including vector databases, embeddings, and semantic search.
Throughout my career, I've worked with companies including Genforge, Envaysoft, and Al Waleed IT, delivering full-stack solutions across web, mobile, and desktop platforms.
Beyond development, I bring deep expertise in DevOps and security: Linux installation and configuration, server hardening, firewall security, custom scanning and monitoring tooling, and comprehensive hosting setup and maintenance.
