Senior AI & Full stack & Data engineer with 10+ years across AI, full-stack web, mobile work, enterprise apps, and data engineering. Most of my backend work is in Python (FastAPI mainly, some Django) and Node.js, with a fair amount of C# / .NET and PHP / Laravel on enterprise projects. On the frontend I work in React/React Native with TypeScript. A good portion of my recent work has been on Microsoft Dynamics 365 and the Power Platform - writing C# plugins and custom workflows, and a lot of client-side JavaScript for form scripts, ribbon buttons, and web resources to handle business logic the out-of-the-box config can't cover. On the data side I build ETL pipelines, data warehouses, and reporting dashboards. I use Spark when the volume justifies it and Airflow to keep the pipelines running on schedule. Day to day I work across MS SQL Server, MySQL, and PostgreSQL. For reporting I mostly deliver in Power BI, and Tableau when the client is already on it. I care about code that's fast, doesn't break in production, and is easy for the next person to pick up. Happy to jump on a quick call to talk through what you need.
