Custom Discord Command RPC Bot Server
Rust

Designed and Developed a custom Discord bot for the purpose of sending Remote Procedure Calls (RPC) to a custom server. This project is composed of 2 parts, a Node.js "frontend" using Discord.js that handles user command events and a Rust "backend" which has a stable First In First Out Queue which can be multi-threaded. The two parts communicate using GRPC protocol buffers. The server then has to executes the command and sends the result back to the bot, which then sends the result to the user. Entirely custom designed and built from scratch and the servers needed to be asynchronus to handle multiple requests at once, optimized and robust so not never fail while the entire codebase had to be clean, readable and maintainable long term.

Invoke-AI
Refactored and cleaned up outdated JS codebase for Discord bot for an Invoke AI Stable Diffusion server. The codebase was using outdated packages and had a lot of commands and functionalities but everything was contained in a single JS file with messy code and global variables for which things like the queue system was handled with. The codebase was refactored to use modern TS with static type checking, using a modular design pattern with each command in its own file and using a command handler to handle all commands. The codebase was also refactored to use modern Discord.js v13 and the bot was also updated to use the latest version of Node.js.

Custom Art Generator
Typescript
Node.js
Sharp.js
Image Manipulation
Design and development of an entire custom art generator along with a suite of command line tools from scratch using Typescript and Sharp.js (blazingly fast image manipulation library). With over 1000 assets, hundreds of of logical rules, and a over 10 000 quality pieces to generate out of unimaginably large number of possibilities, I had to design a system that would be able to handle all of the numerous different requirements and edge cases as well as optimize it to compute as fast as possible and uses true randomness. Requirements were also constantly changing with new ones added often. The result is a blazingly fast and optimized (the bottleneck was the image manipulation library) and flexible system that was able to handle the load.

Smart Contracts
Design and development of the original smart contract library that would be used for the KPR project. The library passed an audit by a third party and was used as a base for the entire project. The library was also optimized to be as gas efficient as possible and to be able to handle all of the different use cases that were required and was also extensively tested with unit tests and integration tests.

Engineered and developed a Web Backend Server to aggregate data from multiple sources and provide a single API for the frontend application. The server is built using Rust and Actix-Web and uses MongoDB as the database. The server is also built using a modular design pattern with each component in its own file and using a component handler to handle all components. The codebase is also fully typed and uses static type checking and uses a custom Fixed Point Number type. The server is also built to be as fast as possible and uses a LRU-cache to cache data and uses websockets to push data to the frontend application.

Smart Contracts
Designed and developed smart contracts for Smolsweep which allows users to buy NFTs and items from multiple marketplaces in bulk. The smart contracts are built using Solidity and are built using the Foundry framework and were tested with unit tests. The smart contracts are designed using a modular and composable design pattern with the ERC-2535 Diamond Pattern with each facet and component of the contract in its own file and using a proxy contract to delegate calls to other contracts from.

Plotly
At Novartis, I engineered a GUI application using Electron.js, TypeScript, and Node.js, designed to streamline the company's sales data handling process. The application interfaced with a Python backend, leveraging powerful data manipulation libraries like Pandas and Numpy to compile, clean, analyze, and export data from various sources. The design of the GUI application was created with the company's brand aesthetic in mind, ensuring a seamless experience for users. To maximize the utility of the application, I integrated Plotly.js for data visualization, enabling users to gain insights at a glance directly within the GUI. The application was globally deployed across Novartis, significantly enhancing productivity and efficiency in the company's data management processes. This project showcases my ability to develop high-impact software solutions that not only meet client needs but also contribute to operational efficiency on a global scale.
