    My name is Vasileios Papapostolou, a 24 years old Computer science grad who is currently pursuing a Master's Degree in "AI and Big data". I enjoy coding, and I have started my journey working as a full time software engineer in a startup. The purpose of freelancing is to gain knowledge and experience. I would like also to help people to give flesh and bones to their ideas. I am more into the engineering part rather than the AI. I have an in depth understanding of ML, DL, and Stats models. I really love graph theory, optimizations, complexity and in general discrete mathematics. Lastly I have to admit my biggest love is Elixir. It's a fully dynamic programming language for building scalable and fully distributed applications. Beyond the powerful Erlang VM I enjoy the syntax, the pattern matching, the macros and a lot more stuff. If you are interested for a more in depth conversation don't hesitate to ping me. My tech stack is the following: Elixir ( main language) Python, Java (good) Frameworks: Phoenix, FastAPI, Flask Kafka, Grafana, Redis, AI stuf: Machine Learning (Scikit) Deep Learning (Keras, Pytorch) Data Analysis( Pandas, Numpy, Seaborn, Matplotlib)
