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.
