Multitalented Blockchain/Software Developer

I am a Blockchain/Software/Game developer but I consider myself a generalist as I can do pretty much anything. I got involved with blockchain since 2017 and have been working for several prominent blockchain projects. I co-founded several blockchain companies with varying levels of success and have gained management experience as well. I'm a big advocate for privacy and decentralization and I believe that blockchain is the future, assuming this industry can still be saved.

Let's connect! My CV

My 💩 projects:

Understanding Solidity Tutorial Series 1-3
NEW

I've written a tutorial series of blog posts teaching about the inner workings of Solidity by writing our own Solidity parser and Virtual Machine from scratch in Rust 😲

New Rholang Parser+Runtime
Rust

I've written my very own Rholang parser and runtime. With my implementation there is no more need for normization/sorting (which was quite an expensive operation) and it's no longer a bottleneck🥳

Visual Rholang SDK
Godot

This plugin for Godot Engine 4 allows game developers to easily integrate blockchain to new and existing games using Solidity and Rholang smart contracts, all without having to write a single line of code. Built mostly in GDScript and Rust.

Timestamp Player

This was my attempt at improving our Youtube channel visibility and digestability of our material at RChain. It's a simple carousell that displays all blog posts with ability to watch video and navigate through timestamps directly from the homepage.

Airspark
Comission

A timecard marketplace and a social platform to monetize your time by minting it as NFTs. Once the NFT is burned - an encrypted DM chat is opened for a limited time between two parties. Built with Svelte and Keystone 6 for backend.
