Kyle Givler

I’m Kyle, a software developer who likes understanding how things work, fixing things that don’t, and building useful software without making it needlessly complicated.

Most of my work is backend-focused C#/.NET running on Linux, with a mix of APIs, self-hosted services, networking, observability, and developer tools. I’m also drawn to the older and stranger parts of computing: Gopher, Gemini, DN42, Yggdrasil, Unix, C, and the occasional game-modding rabbit hole. This site is part portfolio, part workshop, and part record of whatever I’m currently building or figuring out.

Profile

A few projects that best represent the kind of software I like to build.

Infrastructure / applications

Mission Control

A self-hosted operations system combining durable event history with live host, container, and protocol monitoring across multiple machines. Agents collect current state while NATS JetStream carries operational events to the archive and shared web/mobile clients.

.NET · NATS JetStream · SQLite · Blazor / MAUI

Games / applications

Random Steam Game

A fast Steam backlog picker and library exporter built for people with too many games and not enough desire to choose one. It supports unplayed filtering, local exclusions, aggressive caching, and CSV exports with playtime and Steam Deck compatibility.

.NET · Blazor · Steam API · HybridCache · SQLite

Planning / applications

What Should I Work On Today?

A self-hosted planning tool for deciding what to work on when time and energy are limited. It filters todos by available energy and effort, then favors useful work based on project neglect and priority instead of always sending me back to whatever I touched most recently.

.NET · Blazor · EF Core · SQLite · GitHub API

Have something you need built?

I also do paid development and deployment work: .NET, APIs, Linux/VPS deployment, Docker, self-hosting, and infrastructure.

Development Services

Current / recent work

Networking experiments, strange protocols, small tools, and whatever rabbit hole I wandered into this week.

DN42Atlas

A .NET tool for discovering and browsing public DN42 services. It starts from registry data, resolves .dn42 names, conservatively probes web services, respects exclusions and robots.txt, and builds a static viewer from the results.

Source

tcpnoise / Noise Observatory

Small C sensors watch exposed ports for unsolicited connections; a separate .NET observatory turns that stream into sanitized recent activity and aggregate Internet-noise statistics.

DN42 / Yggdrasil

Running a multi-POP DN42 network with BGP, BIRD, WireGuard, IPv4/IPv6, DNS, TLS, and services spread across DN42 and Yggdrasil.

Systems

PlutoAdDetector

An experimental .NET browser-automation tool that detects Pluto ad breaks and switches to YouTube instead, with DOM and learned visual detection plus a Windows GUI.

Source

HappyGopher / HappyGemini

.NET servers for Gopher and Gemini with dynamic content, extensibility, and the assorted small-web experiments I keep attaching to them.

The Lab

Live telemetry, weird protocols, demos, BBS, Internet noise, and questionable experiments.

Noise Observatory — A live, sanitized view of unsolicited TCP traffic observed across my network sensors.
