  • Keras
  • TensorFlow
  • Python
  • Docker
  • Jupyter Notebook
  • pandas
  • matplotlib
  • numpy
  • Convoluted Neural Network that learned how to colorize grayscale images. I directly worked on designing and implementing the convolution layers necesary to achieve this. One nice idea was to include a predefined layer for object detection.
  • Sped up results by including 'imagenet' pretrained object detection layer into our custom designed layers.
  • Leveraged the power of various Python libraries for manipulation and preparation of images. For example, matplotlib, keras.preprocessing.image, skimage.color.
  • As part of development, created tools and functions to easily convert and compare images from grayscale to colored images. This would speed up the learning process and shorten the training time.
  • One example of our results can be seen here: https://github.com/marioscience/image-colorizer-notebook/blob/master/download%20(2).png.
  • The entire process was documented in the mock research paper: https://github.com/marioscience/image-colorizer-notebook/blob/master/Research%20Paper.pdf

“Mario has been an awesome coworker. He's not only been extremely helpful to me, but regularly puts in extra time in the evenings and on weekends to make sure projects are being done on time and that assets are produced in requested sprint cycles. He has a very wide knowledge of all things web development, but more importantly knows what will be best suited to complete any specific projeict and do it in a timely manner. He's got a great sense of humor and doesn't take himself too serious, which is great especially in an environment that may be stressful with deadlines fast approaching. He's also very good at testing new technologies on a projects to make things faster, compact, and efficient. This is one of the easier recommendations I've written as Mario and his skillset and experience speak for themselves and I'd happily recommend him for promotion from within and definitely as a valued team member should anybody be lucky enough to try and steal him away in the future.”
