Experience
Amazon
IT Support Engineer — Network Infrastructure and Security · San Francisco, CA · December 2019 – Present
Thirty-plus buildings ship on this network. When it degrades, they stop.
- Design, deploy and maintain production network infrastructure across 30+ Amazon Fulfillment Center (FC), Sub Same Day (SSD) and Amazon Logistics (AMZL) sites on Cisco and Juniper platforms, including SD-WAN connectivity and Junos-based firewalls.
- Enforce network segmentation and least-privilege access by configuring and tuning firewall policies and Access Control Lists (ACLs), closing security gaps before they reach production rather than after.
- Hold the escalation seat in a 24/7 on-call rotation for network and security incidents across FC, SSD and AMZL facilities, containing breaches and restoring service inside a one-hour response target.
- Automate network and security operations in Python, Bash and PowerShell, cutting manual configuration work by 34.7% and standardising device hardening across every site.
- Keep the Amazon Robotics network environment up, sustaining the connectivity that automated material-handling and sortation depend on — when it drops, the floor stops moving and the site misses its ship window.
Volkswagen Zimbabwe
Software Engineer · Harare, Zimbabwe · 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.
- Worked on the engineering team that replaced Microsoft Dynamics NAV with a custom integrated business management system — ERP and CRM in one product — written in C# on .NET and built around how Volkswagen dealerships actually operate. It is still in production.
- Supported the Dynamics NAV deployment it replaced, writing custom modules in C# for the processes the stock product could not cover.

Projects
Trading app — multi-asset signal platform (Python, TypeScript)
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
Pharmaceutical supply chain provenance (Solidity)
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.

kudzayimwashita.com — this site
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.
