Jan Drabner

Back-&Frontend/Cross-Platform/Generalist Dev & Consultant

    Summary

    I am a qualified Software Engineer / Programmer with knowledge and proficiency in a large number of development topics, as well as a qualified Game Designer.

    I am open-minded and like to refine my existing skills as well as learning new ones and am not afraid of touching new techniques that I have not yet worked with. Due to my experience in multiple different languages and libraries/tools, I tend to get into new ones rather quickly.

    My pet peeves are probably optimization (of both software and workflows), DevOps, software architecture as well as cross-platform development. But have a look at my skills yourself in the list below.

    Please note that I am currently only interested in part-time opportunities (up to 4 days/week).

    Skills

    C/C++

    C/C++ is one of the main programming language I have been working with.

    By now I have worked on a great variety of projects using C++ on anything from library integration, backend & frontend development as well as game development.

    Python

    Python is one of my favourite languages to work with.
    Its enormous amount of functionality and libraries and ease of use make it the perfect tool to develop small to mid-sized tools to be used across projects.

    I have been using Python to some extend almost everywhere I have worked so far, from exporter plugins for 3D software (Blender/Maya) to analyzing tools or larger build scripts.

    JavaScript

    JavaScript is a language that can nowadays be encountered in many environments and is an important language to know for any generalist developer.
    From classic frontend development in pure JS over using it as a development language for embedded systems to Node.JS development, I've been working with it quite extensively in several projects.

    Other Languages

    To not expand this list unnecessarily, here is an assorted list of other languages I have worked with so far - some very extensively, others a bit less, but all of them are languages I would be comfortable in using again at any point:

    Lua, TypeScript, Java, SQL, C#, Rust, PHP, Flash/ActionScript/Air, bash scripts, Objective C, GDScript, Groovy, Asterisk ...

    Tools, Libraries & IDEs

    Since I started programming, I have worked with so many tools, libraries and IDEs that it wouldn't make sense to add each as an own skill.  

    IDEs:
    JetBrains suite (IDEA, Rider, etc.), Visual Studio 2008/10...Code etc., Qt Creator, MonoDevelop, Eclipse, FlashDevelop, NetBeans, Code::Blocks, Codelight, Light Table, Atom, Sublime Text, KDevelop, ...

    Libraries & Engines:
    Seed, Node.js, Electron, FFmpeg, Qt, Ogre 3D, AWS, Azure, Godot Engine, libnoise, Trinigy Vision, DirectX, OpenGL, OpenAL, Noesis GUI, CEGUI, recast/detour, Polyvox, MySQL, Joomla, CakePHP, libccd, NodeJS, Jenkins, Docker, ...

    Tools:
    LibreOffice suite, Microsoft Office suite, PSPad, GIMP, Adobe Photoshop, ...

    Organization

    In many projects I have been part of I usually lead or organized a smaller team of maybe a handful of people.
    Discussing and setting workflows, setting up a task system the team is comfortable with, making sure to always have a  comprehensible implementation plan and of course making decisions some people shy away from.

    But even when working alone, I prefer to be well organized and able to give realistic estimations whenever possible.

    Optimization

    One of my pet peeves is the optimization of processes - as well as knowing when not to waste time trying to optimize something.

    For one, this concerns deep issues within code that can be optimized by restructuring mostly (and sometimes, simply by using a different container), applying different patterns and analyzing performance using various tools.

    But it also concerns processes within the workflow of a company. Sometimes, a small change can make work far more pleasant for everyone involved - hence my interest and often involvement in DevOps-related tasks.


    Spoken Languages

    I am fluent in English and German.

    Additionally, I have basic knowledge of Finnish (~B1-2 level).

    Education

    Interests

    Gaming:
    This shouldn't be that much of a surprise, considering the Games Academy apprenticeship and the knowledge about 3D Engines. I started playing games when I was five years old, and haven't stopped since. I like to play all sorts of games from RPGs to trading card games and complex strategy games on the PC. Either alone or together with friends.

    Programming:
    Besides working as a programmer, I sometimes like to code some random stuff as a hobby and to learn new techniques. It is not my main leisure activity, but from time to time it's definitely fun.

    Music:
    I listen to music when I travel, when I'm at home, sometimes when working, etc. Without a doubt, music is very important to me, although I possess absolutely no skills in creating it, unfortunately.

    Digital Media:
    Another hobby of mine is the consumption of digital media, from YouTube to Netflix or Amazon Prime. I'm no stranger to losing some sleep due to binge-watching a series that I enjoy ;)

    Languages:
    Last but not least, I like to learn languages. This is of course a huge and very time intensive task, but I am doing my best to spend about an on it every day.
    My current goal (as of 2023) is learning Finnish to pass the official language test.
