Board member for our React shared component library called Preamble. The library was shared between 6 engineering teams.Implemented RabbitMQ to keep data synchronized between our applications, allowing us to cache data (such as user information) locally for large throughput increases.Architected the core infrastructure for our zappier-like workflow solution to run multi-stage workflows reliably and easily.Played a huge role in increasing throughput and decreasing technical debt of our large legacy CMS by upgrading it to .net core from .net 4.6.Technologies used: C#, Typescript, React, React hooks, RabbitMQ, Sql Server, Redis, MongoDB, Elasticsearch

https://app.rspeer.orgSide project turned into a side business. 3rd party client for a video game called RuneScape. We provide an API for users to write code to directly interface with the game.User base of over 18,000 while having only 3 owners / developers working part time on this.Full ecosystem written from scratch, including a remote launch system to open clients, a marketplace to buy and sell code, application launcher and automatic updater.Increased throughput and lowered resources needed by utilizing Redis and NSQ for caching and data synchronization between the services.Utilized InfluxDB to store and analyze user data.Created CI/CD pipelines to deploy the many services onto Kubernetes as docker containers. Various parts open source: https://github.com/MaddoxDevelopment/RSPeer-ConsoleLauncher

Rewrite and improve undocumented legacy C# ASP.Net WebForms to a brand new API for large increases in speed, code re-use, and security.Created a custom object-relational mapper to support a legacy IBM DB2. Integrated services with a IBM DB2 RPG backendImplemented CI/CD pipelines to automate manual build and deploy processes.

Single developer for an video game currency marketplace with financial services.As the sole and lead developer, I was tasked with consulting with the client, coming up with a plan, and executing that plan to build the website that surpasses their requirements.I first started off with talking to the client and retrieving a general overview and specifications of what they would like.After receiving these specifications, I worked with the client daily to build the API Server, front facing client, and a back-end administration panel.The client and I communicated almost daily to ensure everything was to their exact specifications.Technologies Utilized:NodeJS, Typescript, Javascript, MongoDB, Socket.IO, Java, Vue.JS, Express.JS

Single developer for an online high-traffic e-commerce site that buys and sells online virtual currencies for different online games.On this project, I was contracted in as the only developer, and it was my task to maintain their old website while building them a new one to meet the demands of their customer base.I worked daily with the owners of the company to help them create an online virtual game currency e-commerce website where they were able to buy and sell online currencies for real currency.Supported payment systems for this website included Paypal, G2A Pay, Bitcoin, Skrill, Bank TransfersOn top of developing this website, I was also contracted to fulfill various other roles such as IT support, Dev-Ops, and general tech support. I managed all the servers, the databases, and all tech related issues that any of the employees or customers had encountered.Technologies Used:This project required a lot of real-time communication to allow for faster and more efficient work done by employees, so we decided on the following:NodeJS, Typescript, Socket.IO, MongoDB, and Java.We utilized Socket.IO to show orders updating in real time between all employees on the Bogla Gold backend, and automatically show new incoming orders.

This role was solo work in regards to creating mods / additions to an online video game called RuneScape.We utilized Java to reverse engineer and modify the runtime code of the video game and read in-game values.With this information, we were able to create modifications to the game client that would allow players an easier time playing the game / becoming more efficient.This was not a traditional job for a company, I was most of the time my own developer, trying to sell apps / add-ons in the website's repository, but for a bit of the time I created custom modifications / additions to the client for customers who required such.These applications would be sold to hundreds or thousands of gamers in the community, and I would provide support on them if anything were to break due to the unstable API from the changing of the game.Technologies Utilized:Java, Java Reflections API, SparkJava, MongoDB
