...thing I've done was for a hackathon where I created a genetic algorithm that was able to learn 3D Tetris from scratch and get extremely good at it.

  • (Development)

    Geneural is a self-made genetic algorithm that learns how to play 3D Tetris from scratch and master it. The results per generation are plotted and clickable for a playthrough from the best chromosome in the generation.

    This algorithm was created using Python and Numpy. No additional machine learning libraries were used as the algorithm was created from scratch by me.

    My team and I won third place in RUHacks, a coding competition, for this project.

    I specifically designed the entire genetic algorithm, code, and concept.

  • Twitter Data Mining: A Guide to Big Data Analytics Using Python (Publication)
    Twitter is a goldmine of data. Unlike other social platforms, almost every user’s tweets are completely public and pullable. In this tutorial, Toptal Freelance Software Engineer Anthony Sistilli will be exploring how you can use Python, the Twitter API, and data mining techniques to gather useful data.
