Why this site exists
A personal site as a long-running engineering project: what it is for, what it deliberately is not, and how it is built.
Ivan Panev
Site reliability engineer, former network engineer, security and automation by inclination. This is where I write things down properly: essays, notes on what I am building, and a few tools I keep reaching for.

Subnetting by hand, still
Calculators are fine, but the arithmetic is small enough to keep in your head, and being able to do it changes how you read a routing table.
Projects
- Home network
Segmented home network with a management plane, an IoT island, and a WireGuard path back in.
- This site and its platform
A static site at the edge, a small Kubernetes cluster behind a tunnel, and the decisions that keep the two apart.
- Encrypted quick notebook
Paste text, code or an image behind a passcode; the server stores ciphertext it cannot read and forgets it after a week.
Tools
- Subnet calculator
IPv4 and IPv6 prefix arithmetic with the binary view, split and supernet helpers.
- Text counter
Words, characters, sentences, bytes and reading time. Unicode-aware.
- Secret generator
Uniformly random strings and EFF-wordlist passphrases, with honest entropy figures.
