FragmentColor (https://fragmentcolor.org) is a cross-platform GPU programming library implemented in Rust and wgpu.

It has bindings for Javascript, Python, Swift, and Kotlin and targets each platform's native graphics API: Vulkan, Metal, DirectX, OpenGL, WebGL, or WebGPU.

The API encourages a simple shader composition workflow. You can use WGSL or GLSL shaders
for visual consistency across platforms while avoiding the verbosity of modern GPU APIs.

We strive to remove the complexity without sacrificing control.

Computer Graphics Engineer - Core Maintainer

In partnership with Bayer Crop Science and NVidia, we created a Deep Learning library (before PyTorch or Tensorflow) that ran natively on Android & iOS to help farmers recognize and treat plant diseases in big crops of soybeans and maize without relying on an Internet connection.

2013 was a good time to enter this space because we started before the Deep Learning boom in the ImageNet competition. We had the privilege of participating in the evolution of the current AI hype in its very infancy. We developed and saw the rise of new techniques and better tooling, the publication of important papers and books, the growth of the community, and the ever-growing media attention to the topic.

Tech Stack: C++, Java (Android), Swift (iOS), PHP (Laravel), Javascript (Vue), Caffe, OpenCV, Python, CUDA.

I worked on the search page's backend and frontend to improve user experience at rakuten.de. I delivered the faceting features of the Search API (based on a fork of Solr), improved relevancy score accuracy, and rewrote a large part of the legacy systems. I have also started a project to automatically fix the incorrect categorization for our 15M+ active products using Machine Learning and custom annotation tools.

Tech stack: PHP (Symfony), Golang (Echo), Javascript (React / Redux), Docker / Kubernetes, Azure, Gitlab.
