I build
Your business needs more than a nice-looking page: it needs a site that's fast, secure and always online. Every project is built as a complete system — from the code to the server behind it.
How can I help you?
From code to infrastructure: everything your project needs to work, scale and stay online.
Websites & Landing Pages
A modern, fast, SEO-optimized site that turns visits into customers. Online with SSL, a global CDN and automatic updates.
Deployment & DevOps
Your project online with enterprise-grade infrastructure: CI/CD, domains, DNS, custom-domain email and edge computing — without unnecessary costs.
Enterprise Networking
From chaotic to professional: VLAN segmentation, high availability and centralized management so your operation never stops.
Servers & Private Cloud
Your own services, secure and under your control: virtualization, containers and private clouds that cut third-party subscriptions.
Security & Remote Access
Secure access to your systems from anywhere: Zero Trust networks, encrypted tunnels, filtered DNS and reverse proxies.
Continuity & Monitoring
Don't let a power outage cost you data: UPS configuration and monitoring with real-time tracking and automated safe shutdowns.
From idea to project in production
A clear process so you always know what's happening and what's next.
Discovery
It all starts with understanding your operation and your goals — before a single line of code.
Proposal
You receive a technical proposal with clear scope, timeline and cost. No surprises.
Development
Development in stages with visible progress: you review and give feedback along the way, not at the end.
Delivery
Your project goes live with domain, SSL and monitoring — and everything documented for you.
Support
Delivery is not the end: maintenance, improvements and ongoing support if you need it.
Projects running in production
Real infrastructure and systems working today — not mockups.
010204.best Platform
This domain is a living project: DNS with DNSSEC, serverless link shortener on Cloudflare Workers, custom-domain email, WAF, and this site with continuous deployment from GitHub.
Enterprise Network Migration
Full transition of a corporate network to enterprise architecture: VLANs, STP priorities, management layers and rack reorganization. Executed during maintenance windows with zero downtime.
Virtualization & Containers
Proxmox VE hypervisor running 10+ services in Docker containers, orchestrated with Portainer and Docker Compose. Full isolation and maximum resource efficiency.
Private Cloud
Self-hosted Nextcloud and Immich: private storage and media gallery with tuned configuration, regional localization and secure remote access.
Zero Trust Network + Private DNS
Encrypted mesh with Tailscale and ACLs: each user only reaches what they should. Local DNS with AdGuard Home and Technitium behind Nginx Proxy Manager. Includes an OpenWrt travel router with WireGuard tunnel.
Power Monitoring (UPS)
Configuration and monitoring of double-conversion online UPS: real-time voltage readings over data link and automated safe shutdowns during outages.
Tech stack
Technologies I run in production, not just in tutorials.

Facts, not promises
Everything shown on this page is running in production: corporate networks migrated with zero downtime, 10+ active self-hosted services, and this very site, published on Cloudflare's global network under its own domain.
A website doesn't end at the design: it lives on a server, travels through a network and depends on DNS. Caring for that whole path is what keeps your project fast, secure and online — and it's the foundation of every delivery.
