Five years and counting of shipping production software end to end: data models, backends and APIs, React frontends, third party integrations, and the infrastructure it all runs on. My recent work centers on AI document processing and case management platforms that I own from first scoping call through production.

An AI case management platform that automates reimbursement appeals for Amazon sellers. I am the sole engineer: I designed the system, built it, and operate it in production.

A Shopify storefront and ad-spend analytics dashboard for an e-commerce brand, a serverless DeepL translation system for Eleveo that saves the team 10 to 15 hours of manual work weekly, WordPress rebuilds for the Dolan Law Firm and others, and Python utilities for OCR, image optimization, and email automation.

Comfortable across ecosystems: Python and Django, Node and TypeScript, React and Next.js, C# and .NET.
I came to software through App Academy after building my first systems in Excel and VBA at a precious metals refinery, where my chain-of-custody work earned a respected third-party certification. Before that I founded and ran a media digitization business.
That path shaped how I work now. I am happiest when I own a product end to end: talking to the client, designing the data model, shipping the frontend, and carrying a pager for the result. Appeals Doctor is what that looks like in practice.
I live in Miami, FL, and I am currently open to full time software engineering roles.
