Hi, my name is

Paul Kokot.

I build fast things for the web

Systems-minded developer based in Europe. I care about latency, clean APIs and infrastructure that fits in RAM you can hold in your head. This whole site — CV, dashboard, 3D playground — runs on a single 4 GB VPS.

01. About

I run my own hardware in the cloud: a game server, this site, a sync service — all wired together with systemd units, FIFOs and far too many journalctl -f sessions. I like boring, observable infrastructure and loud performance numbers.

Day to day I write C#/.NET and TypeScript, tune PostgreSQL, and automate the boring parts with shell. Recently I've been obsessing over byte budgets: this page ships as a single request for the critical path.

Off-duty I administrate a Minecraft server for friends — which is why there's a live server dashboard hiding behind login.

02. Skills

Languages

C#, TypeScript/JS, SQL, Bash, Python, Rust (reading)

Backend

ASP.NET Core, minimal APIs, Npgsql, REST, auth & sessions

Frontend

Vanilla-first, Three.js/WebGL, Core Web Vitals, no-framework builds

Infra

Linux/systemd, Caddy, PostgreSQL, SELinux, firewalld, Docker basics

03. Projects

pk.showcase

this site

CV + dashboard + 3D playground on one VPS. Cookie auth, per-IP rate limiting, precompressed static served by Caddy, HTTP/3.

  • Caddy
  • ASP.NET Core
  • PostgreSQL

Pumpkin MC bridge

automation

Web console for a Minecraft server: status pings over the server-list protocol, console commands via a non-blocking FIFO, live log tail.

  • C#
  • FIFO
  • systemd

Performance budget page

web perf

This page itself: critical path under 50 KB, system fonts, lazy 3D module, live RUM numbers in the hero (your measurements, above).

  • Core Web Vitals
  • HTTP/3
  • zstd

04. 3D Showcase

Three.js loads lazily — only when this section approaches the viewport, only when you don't prefer reduced motion. Drag to orbit.

Drop .glb files into /srv/showcase/models/ and they'll appear in the picker.
