    I have formidable Linux (RHCA, RHCSE) and Java (SCJP) experience, but I am more interested in Python and Android recently and I gathered some knowledge in many distinct areas (Novell, Oracle, MySQL, PHP, Cisco, etc.). I'm a general IT specialist - non-trivial / multidisciplinar problems gravitate to me, as I like to tinker and dissect problems. Having a bit of OCD (even though I prefer the term "perfectionist") I also enjoy menial tasks like cleaning up databases, commenting code or creating user training manuals. I am looking for side jobs, projects.

    I have been working as a software engineer, architect, CTO, and business owner for the past 20 years. Most recently we worked with Wyca Robotics, where me and my team developed an inventory robot for logistics companies using ROS2. We also designed and implemented a container-based robotics platform with an integrated simulation environment to reduce maintenance and development costs. Since 2018 me and my team worked on various projects at Wayray on an automotive AR (Augmented Reality) system. I lead the implementation of an SDK (Android, Docker), Rendering Engine (Godot Engine), VR Simulator (Unreal Engine). We used ROS (Robot Operating System) as the middleware. I also designed and lead the implementation of the AR experience Foxus on top of the Oculus Quest 2 VR headset using the Godot Engine. Our task was to integrate an aftermarket stereo camera with the Quest 2 headset and optimize the system performance to reach 60 fps (camera hardware limitation). As a result of this work we submitted various new features for inclusion in the open-source Godot Engine project. In 2013 we started the development of Migeran for iOS: a product to allow the development of iOS apps in Java. In 2015 this product was acquired by Intel Corporation, and released as an open-source project in 2016 as "Multi-OS Engine". I am the chief architect and project lead of this project. Between 2010 - 2016 me and my team worked on porting Google V8 from ARM to MIPS architecture. We used C++, ARM and MIPS assembly. In the early 2010s me and my team worked on a building Android Set Top Box software, including Skype Video Conferencing on MIPS based Set Top Box hardware. We managed to optimize the system to support HD video calls. Also in the early 2010s me and my team built cross-platform mobile applications for every relevant platform at the time from a single Java source code with custom transpiler technology. Other notable projects: - Android platform and app development - iOS app development - Web & Enterprise app development - Embedded app development - Siemens Mobile Phone development

    My first job is started at the end part of university, on a field that I actually did not think about to work in. Still, this test automation position held a lot of challenges, and things to learn, while also developed my team player and communication skills. This adventure still goes on, and I am looking into the future to meet even more new knowledge and experience.
