About Me

Hi, welcome to my home page. I am Hendrig, currently working as a software engineer at RingIT (Tallinn, Estonia). I hold a B.Sc. degree in Informatics from TalTech (Estonia) and an M.Sc. degree in Computer Science from Delft University of Technology (Netherlands).

I specialize in software development, but I like everything related to technology and also have some experience in data science / machine learning. Feel free to reach out to me through Linkedin!

My Expertise

Backend

I have mostly worked with Java in the backend and my current experience spans 4 years. The databases backing those systems have been SQL based, such as PostgreSQL and Oracle DB.

Frontend

I've worked with Vue and JSF (Primefaces) professionally. Since I've had experience in web development, I'm also familiar with React and tools such as NPM, Gulp, Sass and Yarn.

Machine Learning

Tensorflow Keras Numpy

During my studies at Delft University of Technology I have used Keras API running on top of Tensorflow to reproduce state-of-the-art research in addition to libraries such as numpy and pandas to ease data manipulation.

Other

As a developer, I'm always looking for ways to enhance my workflow. The software I've used are the industry's standard, such as IntelliJ IDEA, git, AWS, Google Cloud and Tomcat Servlet.
