💫 welcome to Nuno's website!

I am based in Madrid 🇪🇸

Among other things, I'm into:
open source software & cybersecurity

& music/DJing.

I work in software development as a full stack engineer and am most comfortable with:

🐧 Linux (Arch, Fedora, Debian, Alpine, Centos, etc.)
📦 Podman and Docker
☸️ Kubernetes
📘 TypeScript
🟢 NodeJS
🐹 Go
☕ Java
⚛ React
#️⃣ Bash
📘 Powershell
🐘 Postgres DB
🚜 AWS
☁️ Cloudflare
➕ and many others...

Here's some highlights:

• guitos
  • A personal budgeting app that helps you figure out where your money went, plan your budget ahead of time and analyze past expenditures.
• A bunch of exporters. These are mostly containerized 🐹 Go cli tools that massage API data to an InfluxDB compatible format and then are consumed by Grafana dashboards in my home server.

Over the years I have learned from the following resources:

• teachyourselfcs.com
  • It helped me create solid foundations for working in the tech world. I appreciate being able to connect the dots from top to bottom, left and right in the technology world.
• bankeronwheels.com
  • Easy to follow guides for understanding financial instruments in the personal context.
• reddit.com
  • from niche to mainstream, anything can be found and discussed here. Moderation and quality of the content might be inconsistent due to the size of the platform.

I keep up with the flow by subscribing to these streams:

• hackernewsletter.com
  • hacker news' curated articles delivered in a daily/weekly cycle.
• lobste.rs
  • lobste.rs has a smaller community with stricter moderation when compared to hacker news.
• Frontline
  • Frontline is an investigative documentary program covering american and international issues including terrorism, elections, environmental disasters and other sociopolitical issues.
• Legible News
  • A minimalist news aggregator.
