Experience

Random Superhero Generator

This is a learning project where I acted as the lead developer. We trained a recurrent neural network (RNN) on superhero names and used a bot on Botsin.space to connect with our name generator. The names are generated two times every day using AWS Lambda.

Time-series Clustering

https://dspace.cvut.cz/handle/10467/86138

For my master thesis, I managed to acquire data from a distribution system operator (DSO). I analyzed the data using Python (pandas) and I developed a use case for the DSO on how to squeeze as much as possible from smart metering data. I then used k-means to cluster the time series of individual customers. This can help with creating and updating load profiles for better electricity consumption predictions.
The files named PRILOHA are outputs from Jupyter Notebooks.

Restaurant Visitor

https://github.com/loukotal/resvis-be

This was a small project which I took on to grow my skills and learn how to use Node.js. It is a dockerized application using Express.js and the Sequelize ORM. In this project, I wanted to showcase that I could implement my recently acquired skills without any problems while maintaining good quality.
