I am a machine learning engineer who is passionate about solving real-world problems using machine learning algorithms. I am experienced in image processing using OpenCV and PIL, and also in data visualization using Matplotlib. I have been working on various vision-related projects, ranging from image retrieval, OCR, document image analysis and reconstruction, to video fingerprinting/deduplication.

I am also a FOSS lover and a Vim/Nvim enthusiast in particular, sharing tips and tricks on using Neovim. More info about me can be found on my website: https://jdhao.github.io/.
