About Anthony

Developer since 2016, I work across the entire technical chain: modern user interfaces, robust backends, and high-performance components.
I assist teams in designing and developing complete web applications, with a strong focus on code quality, performance, and scalability.

Personal R&D Projects:

Hooks: A very lightweight implementation of React Hooks, designed to minimize code size while remaining compatible with the React ecosystem.
Hlang: A simple low-level language I created, with automatic memory management (and manual control possible). It is optimized for performance on x86-64 architecture.
OS and runtime in Hlang: An operating system I designed and use in production for my own projects. It can handle a large volume of network requests (including UDP and TCP HTTP/2) and serves as a basis for key-value stores, producer-consumer databases, and website hosting.

These tools are available under a commercial license for interested companies.

Technical Stack:
Front-end: React, TypeScript
Back-end: Node.js, PHP, Python, C#
Systems & performance: C, Rust, Go, H_
