Dan Jharahy
Python Engineer — Backend, Data & Fintech Systems
Founder of DJ Strategy LLC. I design and ship production Python systems: REST/WebSocket API integrations, real-time market-data pipelines, algorithmic strategy engines, and cross-platform desktop applications. I care about fault tolerance, clean architecture, and code that holds up under real money and real load.
