👁️🗨️ Welcome to the Dark City
Тьма, пришедшая со Средиземного моря, накрыла ненавидимый прокуратором город. Исчезли висячие мосты, соединяющие храм со страшной Антониевой башней, опустилась с неба бездна и залила крылатых богов над гипподромом, Хасмонейский дворец с бойницами, базары, караван-сараи, переулки, пруды... Пропал Ершалаим - великий город, как будто не существовал на свете.
— Михаил Афанасьевич Булгаков, Мастер и Маргарита
This is a personal knowledge space and experiment log by Andrey Vernigora, architect, engineer, and tooling obsessive.
The goal here is simple: to build and document systems that work — not in theory, but in production.
PowerShell, Azure, Jupyter, and a bit of graph magic.
Whether it’s visualizing traffic through Azure Firewall, scraping SEC Form 4 data, or forcing ZScaler to play nice with CLI tools — this is where I keep track of how things actually work (or don’t) in modern enterprise environments.
🔍 What you’ll find here
- PowerShell notebooks for automation, scraping, CLI prototyping
- Hands-on examples of Cloud Architecture, Networking, Automation and everything around IT that I touch on
- Workflows combining Jupyter, .NET Interactive, Vega, and D3.js
- Notes on CAF, Kubernetes networking, and Azure infra gotchas
- Prototypes of tools like
PSGraph,ipmgmt, andOut-Display - Walkthroughs of real debugging sessions and toolbuilding hacks

I’m a systems architect working primarily with Microsoft Azure, enterprise automation, and modern tooling.
This blog is an attempt to make technical work a little more transparent, repeatable, and visual.
If you’re into real-world infrastructure, interactive data stories, and applied scripting — you’re in the right place.
No fluff. Just shell, charts, and the occasional rant.
