04 / SELECTED WORK
What I’m building.
I build tools for software, cloud and hardware. These are the projects behind that work.
PUBLIC REPOSITORY
open.content.blogs↗
I’m exploring publishing with GitHub and Markdown as the content layer. This project treats a post as a file that can be versioned alongside the platform.
PUBLIC REPOSITORY
open.comingsoon.template↗
I use a coming-soon template to connect a project announcement with public repository activity. The idea is to give visitors something concrete to follow before a launch.
PUBLIC REPOSITORY
open.scripting.template↗
I’m interested in treating shell scripts as software that deserves structure. This template is aimed at cloud tooling and skills for AI agents.
PUBLIC REPOSITORY
open.offline.docs↗
I bring framework and language documentation into an offline system built around Docker. The project focuses on keeping reference material available without a live connection.
PUBLIC REPOSITORY
open.cloud↗
I keep a collection of cloud-native applications intended for self-hosting with Docker, Alpine and Proxmox. It brings the infrastructure side of my work into one repository.
PRIVATE PROJECT
puppet.engine↗
I’m building a desktop workspace for Bold Engineering that brings a browser, code, agents and Lab apps into one place.
PRIVATE PROJECT
bold.cli↗
I’m working on a command-line wrapper for T3Code. It gives this part of my tooling a terminal entry point.
PRIVATE PROJECT
puppet.mobile↗
I’m building a mobile client for the Puppet desktop app. It extends the workspace into a second interface.
PRIVATE PROJECT
minions.iot↗
I collect Arduino and ESP32 sketches connected to Arduino Cloud. This is the hardware side of my interest in software and robotics.
PRIVATE PROJECT
gardeners-cloudrun-ollama↗
I’m exploring an Ollama instance on Google Cloud Run for image processing. This project connects model serving with a managed cloud runtime.
05 / WRITING
Notes from here.
Open weights, real choices
What control over a model means for memory, evaluation and the work around it.
Self-hosting starts with recovery
How recovery, resource limits and maintenance shape the choice between cloud and self-hosting.
