A workshop of software,
built in the open.
I'm a developer from the baryo. I build software across JavaScript, Go, and .NET: libraries you can install, products you can sign into, and the tools that deploy them. Everything below is real and running.
- TypeScript
- JavaScript
- Go
- C# / .NET
- Vue / React
- Docker
- PostgreSQL
# real packages, across ecosystems. copy one, it works.
$ npm install feed-slurp
$ npx create-baryo-app
$ go install github.com/BaryoDev/BaryoVM/cmd/baryovm@latest
$ dotnet add package Verdict
$ docker pull arnelirobles/barako-cms
# or skip the install, it's already running:
# playground.baryo.dev/barakocms
$ Built to be used, not just shown
Each of these started as a problem I ran into, then got packaged so other people could use it. Some are libraries, some are running products, some are command-line tools. Three of them you can try in your browser right now without installing anything.
All projects, with the use cases →

Anyone can list technologies. This is a system you can sign into, in a browser, today.
playground.baryo.dev/barakocms An event-sourced headless CMS I designed and built: .NET API, Next.js admin, PostgreSQL. I packaged it as multi-arch containers and deployed it onto a Linux box I provisioned and hardened myself, with SELinux, a firewall, TLS that renews itself, a reverse proxy, health checks, and nightly backups. Sign in with demo_admin / BarakoDemo2026! and break something.
Front end, back end, database, containers, TLS, and backups, behind one URL you can log into.
The whole span, and where it shows up
Every tool here is in something on this page, or in something I shipped for a client. The list runs from a Figma file to a server that renews its own TLS, with a few languages along the way.

The bottom rows are the ones I've spent the most years on: modernizing legacy systems and keeping them running in production. There are stories behind those on the blog, minus the client names.
Latest activity
Pulled straight from the GitHub API. This is what I'm working on right now.
Get in touch
Happy to talk about any of this: a package you're using, a bug you found, or something you're building. The blog goes into how these got made, and into the client work I can't open-source.
