Experience

Tsanga Inc.

Co-Founder, CEO, Software Engineer

January 2020 - Present

[email protected]

  • Designed and implemented a fully-automated multi-environment DevOps pipeline that automatically built and deployed microservices to an environment-scoped Kubernetes cluster.
  • Developed a web-based SaaS called Toad.app / Jibe.tv allowing consumers to control a virtual browser within their browser, providing a richer Netflix-party type experience allowing friends to consume media online together.
  • Developed and documented Toad's back-end RESTful API in Kotlin using ktor, backed by Redis and MongoDB. This application was designed to be stateless, allowing automated horizontal scaling in Kubernetes via our infrastructre-as-code with Terraform.
  • Designed and developed an OpenAPI/Swagger specification for nectar, a RESTful API allowing for automating and managing game server deployment and scaling via Docker and Kubernetes.

Hypixel Inc.

Developer

November 2020 - November 2021

  • Hypixel is the world's largest Minecraft (Java Edition) server, with peaks of over 200,000 concurrent players online during my time working there.
  • I wrote code primarily for the SkyBlock game: from content, to bug fixes, item duplication patches, and internal tools. SkyBlock is a large MMO-style game within Minecraft itself, pushing the boundaries of what is possible within the game. Players have their own islands, but also community islands, dungeons, quests, a massive economy, and more.
  • Designed, developed, tested and deployed a brand new system called "Storage" for "backpacks", which was an extremely problematic item system plaguing the SkyBlock game, causing mass duplication glitches and contributing greatly to negatively impacting the game's economy. The new and improved system proved effective in entirely removing any duplication glitches resulting from the former backpacks system.

Universal Music Group

Software Engineer

August 2020 - December 2020

[email protected]

[email protected]

  • Designed a front-end statically-served website in Vue.js for SongVault, a platform allowing large YouTube content creators to use UMG songs without being copyright claimed.
  • Developed a back-end RESTful API in Node.js with Express.js for SongVault, utilizing PostgreSQL via Sequelize.

Hylist Games

Software Engineer

October 2019 - August 2020

[email protected]

  • Designed and developed features and bug-fixes on a daily basis within weekly sprints alongside 8 other developers. Worked as a team to complete regular goals and to improve the player experience.
  • Wrote 40,000+ lines of Java + Kotlin code used in production 24/7 by hundreds of thousands of unique players.
  • Set up a CI/CD environment with GitHub Actions / Packages which eventually migrated to Artifactory.
  • Designed and developed a complex Bot system in Java using simple & complex behaviour trees, which allowed players to fight bots of different difficulties and variations.
  • Optimized and improved MongoDB and Redis database usage, schemas, and designs to allow for little-to-no performance impact from database operations and to allow for an increased number of concurrent players.

  • Designed, maintained, and developed an all-in-one Hardcore-Factions plugin -- allowing players to band together, protect land, battle, and compete for the top spot.
