Software developer, Fedora Linux addicted
Hello everyone! I'm Alexxiy.
My developer path began back in 1996, when I was around 12 years old, learning BASIC on the legendary ZX Spectrum. Through the early 2000s I mostly wrote Pascal and Delphi. In 2007 I moved into the web, picked up PHP and its whole stack, and at the same time went deep into Linux — server setup and configuration, security audits and hardening. In 2017 I started exploring the crypto space and soon joined the development of several crypto projects.
From 2008 to 2015 I built and ran a social network for my country — think Facebook, but within the borders of a single country. It grew into the largest social media platform there, with over 2.5 million users.
Below you can get to know me a little better.

What I'm working on
Name services and node infrastructure for privacy-focused blockchains.
pivx.name
PIVX Name Service
Short, human-readable names for PIVX shielded addresses — 78 characters replaced by eight. Names live in the .pivx, .private, .secure and .safe zones, bound to the owner's Ed25519 key, with a one-time fee and no expiry.
The whole registry is a chain of shielded transactions on mainnet: anyone can replay it with the published viewing key, which makes the service fraud-evident rather than merely trusted. Comes with a built-in marketplace for buying and selling names.

zcashnames.co
Zcash Name Service
The same idea carried to Zcash: a memorable name such as nine.zcash instead of a 106-character Unified Address. Five zones — .zcash, .zec, .private, .secure, .safe — all under identical rules and pricing.
Registrations are permanent: no renewals, no expiry, no way for anyone to reclaim a name. Keys never leave the owner, and names use only lowercase letters, digits and hyphens, so homograph spoofing simply has nothing to work with.

- Permanent ownership
- Verifiable registry

nodus.alexxiy.top
Zcash node list, monitoring & API
A directory and health monitor for Zcash light-wallet nodes. Tracks block height, online status, latency, 30-day uptime and the running Zebra / lightwalletd versions, across mainnet, testnet and Tor .onion endpoints.
Everything the dashboard shows is also available over a public API, so wallets and services can pick a healthy node programmatically. There's a world map of node locations, multi-language UI, and anyone can submit a node to be monitored.
It's just as useful on the operator's side: a Telegram bot watches your nodes and sends an alert the moment something breaks, so you can act on the problem straight away instead of finding out hours later.

Previous projects
The ones worth singling out — there were plenty of others along the way. Roughly two decades of things that were built, shipped, scaled and, in some cases, switched off.

2007 — 2010
City web portal
The web portal of my city — chats, forums, news and everything else a local portal carried back then. A typical early-2000s city site, and one of the most popular places in town to talk to people and find out what was going on.

2008 — 2015
National social network
A social network built for a single country. By 2011–2012 it was the largest social media platform there, with more than 2.5 million users, running on 18 servers split by role — application, database, content and others — operating as one system.
It shut down in 2015 as the country's economy deteriorated. The domain was later revived by a group of enthusiasts running an off-the-shelf social network engine.
- 2.5M+ users
- 18-server cluster
- Distributed architecture
- High load

2015 — 2020
Geo-social platform
A location-driven social platform. It won a national startup competition, but never found the funding it needed to go further.

Privacy coin — lead developer
Lead developer on a privacy coin (a PIVX fork, no longer active). I maintained the Core Wallet and built the infrastructure around it: web and Telegram wallets, an OTC platform, masternode monitoring and more.

Private social network
Designed and developed a social network — a lightweight Instagram-style platform — as a private commission for a single client.

My career
The day job that ran alongside most of the projects above.
Full-time developer
From 2007 to 2021 I worked full time as a developer at a number of companies. The longest and most interesting of them was GoDigital Media Group, where I spent almost six years maintaining and developing the content distribution system that delivered audio and video to the major streaming platforms.
I worked on the PHP stack, and my core skills there were video, audio and image processing — transcoding above all.

Say hello
Always happy to talk about privacy tech, Linux, or an odd idea that needs building.
