Projects I liked most

🦄 = Blockchain related project

🦀 = Rust related project

• 🦄🦀 SimplePool and a Substrate Node: This project aims to create a pallet to manage a liquidity pool. A user can stake a token (e.g. a DOT) and receive a liquid token (e.g. LDOT).
• 🦄 NFT Swap: An NFT marketplace focused on Atomic Swaps. The contract is in Solidity and the Frontend is in Next.js. At the moment we are working on several EVM testnets and the frontend is hosted on Cloudflare Pages.
• 🦀 OOTP (Open One-time Password): A library (available for both Typescript and Rust) plus a frontend (in Flutter) to generate HOTP (HMAC-based One-time Password) and TOTP (Time-based One-time Password).
• 🦄 solana_pay: Next.js store that supports payments using the Solana blockchain. Exploiting Solana Pay!
• 🦄🦀 buildspace_solana: Smart contract and related React frontend to save your favorite GIFs on Solana
• 🦀 rusty-mqtt: A Rust bridge between the MQTT broker of The Things Network and ThingsBoard.
• 🦀 rust_rsa: A simple RSA implementation in Rust developed to anchor theoretical concepts behind RSA.
• 🦀 rust-hmac-sha: A pure Rust implementation of the Hash-based Message Authentication Code Algoritm for SHA-{1,2,3}. This project can be seen as an interface/wrapper for the RustCrypto crate, focusing on user/developer ease of use. Works in a #![no_std] environment.
• 🦀 decode-git-object: A small Rust utility that decodes git objects, mainly useful for forensics, recovery, and CTF challenges 🚩.

Favourite quotes

Building software systems is a constant wrestling match between ideals, pragmatism, aesthetics, and time. Reality never quite matches the ideal. Nothing is ever perfect, but things can be good.

-> Rob Habermeier, Polkadot founder

Be curious, not judgmental

-> (Not) Walt Whitman

Curious about the origin of my surname? My grandfather was Croatian, from an island near Split (/ˈsplɪt/, as in the English word "split") 🇭🇷
