E61

For many years I have been designing and maintaining web systems — from application code, through databases, to the servers everything runs on. This site is E61's public notebook: work, tools and things that interest me.

cat what-i-do.txt

▸Backend applications — PHP / Laravel, REST APIs, integrations with external systems
▸Databases — schema design, query optimisation, MySQL / MariaDB
▸Infrastructure — Linux, nginx, containers, virtualisation (Proxmox), networking
▸Automation — scripting, CI, monitoring, keeping production systems alive

ls projects/

e61.pl ↗

[prod]

Laravel 11 · Tailwind 4 · MariaDB

This site — a terminal-style portfolio: work, tools, interests.

Invoicing system integrated with KSeF (Polish national e-invoicing platform) — issuing, dispatch and status tracking of structured invoices.

homelab

[prod]

Proxmox · LXC · Docker · Kubernetes · Samba

Home server room on Proxmox 9: LXC containers, SMB file server, live monitoring on a physical console, backup automation.

nemesis

and many more — client and internal projects this site keeps quiet about.

empty slot — next project in the making

ls tools/

PHP / Laravel MySQL / MariaDB Linux / Debian nginx Proxmox / KVM Docker Git Bash JavaScript Tailwind CSS Redis / cache WireGuard / VPN

cat now.txt

●Extending e61.pl — version 3: content, interactive terminal, feed

●Homelab housekeeping: monitoring and backup automation

// updated: 2026-06-12

cat interests.md

# homelab — a server room of my own: virtualisation, storage, backups and monitoring on hardware that can break without consequences.

# self-hosting — services under my own control instead of the cloud: files, automation, tooling.

# systems — how things work under the hood: networks, protocols, performance, security.
