I build AI, Cloud & Data Systems for investment and financial applications
I’m Demaro Jones — a Software Engineer building investment applications and data pipelines at Unum. I work on the tools that Portfolio Managers, private placement pricing analysts, and credit scoring analysts rely on every day.
I write about what I’m actually building: Bloomberg and Clearwater data integrations, AI-assisted credit scoring systems, .NET modernization, and AWS architecture in the context of real financial and investment systems. No generic tutorials. Notes from the inside.
