radarsu/README.md

Hi, I'm Artur Kurowski 👋

radarsu logo
Simplicity is the ultimate sophistication.

Full-stack TypeScript engineer focused on scalable backend systems, developer tooling, and decentralized architectures.

🌍 Based in Warsaw (remote)
🔗 Website: https://radarsu.com
📌 GitHub: https://github.com/radarsu


👨‍💻 About Me

I build clean, reusable, and production-ready software across backend, frontend, infrastructure, and developer tooling.

My primary focus areas:

  • 💡 CLI tools and developer experience
  • 🚀 TypeScript / JavaScript ecosystem
  • 🛠 NestJS and Angular applications
  • ⚡ High-performance libraries
  • 🌐 Decentralized and peer-to-peer systems
  • 🔐 Data ownership and transport-agnostic protocols
  • 🧠 Maintainable architecture and long-term scalability

I am particularly interested in decentralized architectures, distributed systems, and P2P communication models that reduce central authority and improve data sovereignty.

radarsu/README.md

Hi, I'm Artur Kurowski 👋

radarsu logo
Simplicity is the ultimate sophistication.

Full-stack TypeScript engineer focused on scalable backend systems, developer tooling, and decentralized architectures.

🌍 Based in Warsaw (remote)
🔗 Website: https://radarsu.com
📌 GitHub: https://github.com/radarsu


👨‍💻 About Me

I build clean, reusable, and production-ready software across backend, frontend, infrastructure, and developer tooling.

My primary focus areas:

  • 💡 CLI tools and developer experience
  • 🚀 TypeScript / JavaScript ecosystem
  • 🛠 NestJS and Angular applications
  • ⚡ High-performance libraries
  • 🌐 Decentralized and peer-to-peer systems
  • 🔐 Data ownership and transport-agnostic protocols
  • 🧠 Maintainable architecture and long-term scalability

I am particularly interested in decentralized architectures, distributed systems, and P2P communication models that reduce central authority and improve data sovereignty.
