Hi, my name is Paul. I can create web applications and cloud computing infrastructures. I'm acquainted with powerful Python and JavaScript platforms (Django, Twisted, Flask, React, Vue). I can help you deploy complex pipelines and APIs with Amazon Web Services. I have worked within the robotics industry; among my biggest achievements is developing asynchronous robotic services (Twisted, ZMQ), as well as custom, cloud-based Continuous Integration solutions for unit-testing such services inside volatile virtual servers (AWS, GitHub API).

My favorite topics, though, are Machine Learning and Artificial Intelligence. I have been involved in producing Inference Services with performant data pipelines for real-life applications (CUDA, Tensorflow). Additionally, I have a couple of hobby projects which showcase related concepts I also enjoy, such as neuroevolution and genetic programming.
