Network Security Engineer
Network security engineer with six-plus years running production infrastructure for Amazon fulfillment operations across 30+ sites. Cisco and Juniper at the core, Junos firewalls at the edge, segmentation and ACL policy as the control, and packet-level forensics when that is not enough. Finishing an MS in Computer Science with a cybersecurity concentration at Arizona State, December 2026. Four years writing C# before that, on a system still in production — so the automation is written by someone who has shipped software for a living.

IT Support Engineer — Network Infrastructure and Security · December 2019 – Present
Thirty-plus buildings ship on this network. When it degrades, they stop.
Software Engineer · 2014 – 2018
Four years of C# before networking. We replaced Microsoft Dynamics with something built for how dealerships actually work, and it is still running.
Full-stack day-trading platform: an async FastAPI backend (~8,500 lines of Python) on PostgreSQL, Redis and SQLAlchemy 2.0, a React/TypeScript web client, and a React Native app sharing the same API. Five market-data providers — Yahoo Finance, CoinGecko, Alpha Vantage, Polygon, TradingView — sit behind one interface with an aggregator in front, and brokers behind another, so paper trading is the default path rather than a mode you have to remember to switch on. Signals combine 15+ technical indicators and candlestick pattern recognition with a scikit-learn price-direction model. JWT auth, Alembic migrations, WebSocket streaming, Docker Compose for the whole stack.
Private repository — happy to walk through it
Graduate coursework, ASU CSE 540 Engineering Blockchain Applications, Spring 2026, Group 12 (co-author). Solidity contracts tracking custody of pharmaceutical batches across manufacturer, distributor and pharmacy, so counterfeit inventory cannot be inserted without breaking the signature chain, with a TypeScript application layer around them.
An interactive network-recon console that is a Python program: CPython compiled to WebAssembly via PyScript/Pyodide, with the game engine kept as a browser-free module so it runs under pytest. No hand-written JavaScript.
