01 / Areas of focus
Where code meets curiosity.
From building applications to running the infrastructure behind them, these are the areas I keep returning to.
Automation & DevOps
Deployment workflows, developer tooling and repeatable ways to get software running.
Homelab & infrastructure
Self-hosted services, networks, cloud connectivity and learning by running things myself.
AI & experiments
Local language models, benchmarking and exploring what's possible with today's tools.
02 / Selected work

THE PERSON BEHIND HENNSA
Carlo Hennsa
Software developer. Systems enthusiast. Forever curious.
03 / Behind the work
Hi, I'm Carlo.
I'm a senior software developer working primarily with .NET and modern web technologies. I enjoy the whole process, from figuring out how a system should work to building it and keeping it running.
Outside day-to-day development, I spend a lot of time experimenting with my own infrastructure, automation and local AI. HENNSA is where those interests come together.

04 / Resources
Tools, notes & references.
Useful material from my own work, starting with the document design system that inspired this site's visual identity.

HENNSA Document Style
An independent technical document style guide with reusable HTML examples, design tokens and AI-friendly reference material. The same navy, blue and restrained gold palette is used here.

HENNSA will grow as projects take shape and new things are worth sharing. For now, have a look around the workbench and the resources.
