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)

I am an active and self managed software engineer, eager to get his hands dirty solving challenging problems for organizations of all sizes. My past experience has given me vast knowledge into multiple different infrastructures (Nutanix AHV, vmware ESXi, OpenStack KVM, etc). With strong automation skills, I have architected an end to end deployment utilizing vRealize Automation & Orchestrator with deep integration with SaltStack and multiple vCenters. I managed to reduce the number of templates to manage along with a much more reliable provisioning and decom process. I have also repeated the same with Scalr, however instead of vCenter, I used Azure & OpenStack. In my part time, I have a hotel booking site I managed that I have hosted on Azure along with multiple other sites that I've hosted on GCP and AWS. I like to learn about what each product has to offer and utilize the strong points of each. I developed full stack applications along with simple micro-services with .NET C# / Django Python / Java. These applications varied from being simple websites with backend management to building sophisticated IP Address management tools and batch job like applications.
