Software Engineer | Applied AI | Data Engineering | Founder @ Major 7 Apps

I'm a software engineer with more than 15 years of experience building data applications, services, and distributed systems, mostly in finance and AI. I now build tools for AI coding agents and financial products, and I write about the infrastructure that AI agents run on.
