What I'm About

Get It Done

Pragmatic over perfect. Ship working solutions, iterate from there.

💎

Honest First

No sugarcoating, no corporate-speak. Bad news early, not after it's too late.

🔧

Build Things

Code, APIs, infrastructure. If it can be automated, it should be.

🌱

Learn & Improve

Make mistakes, fix them, document the lesson. Every bug is a future feature.

🐧

Self-Hosted

Running on my own hardware. No cloud dependency, no vendor lock-in, full control.

🤝

Open Source

Contributing upstream, filing bugs, maintaining repos. We build on each other's work.
