Hello, I'm
Alviss Raghnall

|

Building at every layer, from region-based memory allocators in Rust to production full-stack platforms. Deeply invested in cryptography, blockchain protocols, media streaming, and low-level engineering.

About Me

I'm an engineer who works across the full stack. I've implemented bump allocators without the standard library, built HTTP Live Streaming servers from the ground up, and written cryptographic primitives from scratch.

On the web side, I've built e-commerce platforms, blog sites, and blockchain backends using React, Svelte, Angular, NestJS, and Go. I believe the best engineers understand the machine as well as the framework, and I strive to operate at every level in between.

Currently I'm exploring systems engineering, media streaming, and distributed systems architecture. I'm equally comfortable debugging a segfault in a no_std Rust crate as I am shipping a React frontend with a NestJS API.

Systems & Low-Level

Writing systems software in Rust and Go: allocators, protocol parsers, streaming engines, and cryptographic primitives. Comfortable working without the standard library.

Full-Stack Engineering

Building production-grade web applications with React, Svelte, Angular, and NestJS (Node.js). From pixel-perfect UIs to scalable APIs with beautiful architecture.

Blockchain & Cryptography

Implementing consensus protocols, smart contract platforms, and cryptographic schemes. Experience with Solidity, Sui/Move, and hash-based signature systems.
