Software developer and open source contributor

Hi, I'm rubenwardy

I’m a software developer, an open source contributor, and a graduate from the University of Bristol. I’m a core developer for Minetest, an open source voxel game engine.

I have a diverse range of interests, both technical and non-technical. Some examples include Android development, Game development, and Physics.

Multiplayer Topdown Game

For the last four years, I’ve been working on a sandbox game using C++ and SFML. The game renders the world as a topdown cross-section, with support for changing the z-level by walking up and down stairs. The game will be a base building game where you hide from a dystopian government.

The original aim was to use C sockets to learn about lower level multiplayer networking concepts - such as reliability, latency mitigation, and prevention of cheating. However, the focus has since changed to developing this project into an actual game with interesting new mechanics.

I post in-depth tutorials and articles on my projects on my blog around once a month. See below for the most recent posts.

Experience

  • Software Engineer Sep 2019 - Present

    Working on infrastructure for running physics calculations in the cloud, using Python, Flask, Celery, Kubernetes, MongoDB, and Docker.

    Worked on jet engine noise prediction software and desktop GUI applications, written in C# WPF and Java Swing.

    Increased team productivity by pioneering an automated Jenkins CI pipeline to run unit and UI tests. This freed developers up for 15 minutes each invocation, resulting in team savings of more than an hour per day.

    Commended for the ability to quickly ramp up on new projects, and efficiency in producing work.

    Participated in agile / scrum development with daily stand-ups and planned sprints, and performed test driven development and peer code review.

  • Arm

    Linux Kernel and Android Intern Jun - Aug 2018

    As part of a Research and Development team, I worked on experimental changes to the Linux kernel to improve memory security on Android. The aim of these changes was to protect Android devices from both local and remote threats, such as malicious applications or networked actors. A typical task involved making changes in C and ARM Assembly to the Linux kernel, and then modifying user-space C++ tests to verify correctness.

  • GWS Media

    Android and Backend Developer Mar - Dec 2017

    I worked part time as an Android, iOS, and Backend developer for 9 months alongside my studies, gaining valuable experience in client interaction and agile development. I worked on a number of different projects, both individually and as part of a team. I took pride in ensuring that my work was delivered to the highest standard, following platform design guidelines and best practices. One such app.

  • CERN

    Collaborator Jul 2019 - Dec 2019

    Worked on Craft the Web, a game to teach young people about the origins of the world wide web.

    Guest speaker at CERN during the Codez la Science conference (slides).

  • Minetest

    Core Developer and Contributor Aug 2012 - Present

    Minetest is an open-source voxel game engine, which I am a maintainer for. I regularly review pull requests, and have contributed over 100 patches.

    Things I’ve directly contributed include:

    • An in-menu installer and package manager, and a backend for it called ContentDB.
    • The Minetest Modding Book.
    • Lua assertation and integration testing framework, to improve quality assurance and prevent regressions.
    • Assorted GUI features, including styling and a shared inventory GUI library.

    I’ve also created a number of third-party projects, including an Android app to install mods, a 3d voxel modelling program, and lots of games and mods.

    I attended as an official exhibitor at both Freenode Live conferences, in 2017 and 2018.

    Participating in this project has given me a proficiency in Git, Linux, and collaboration.
