    I am a data scientist and software developer with experience in creating applications with R and Python to deploy fast and reliable data science projects, especially applied to research on natural systems in combination with SQL databases and external APIs. Some of my daily work includes: - Python and R package development to ease testing and maintenance. - Managing and creating R Shiny dashboards to reveal data insights. - Full CI/CD of projects onto Kubernetes clusters with Docker images. - Combining R-Python-SQL to leverage computation effort. - Distributing logic on different dockerized components (MVC design). - Creation of REST-APIs to allow fast computations on SaaS. - Applying Clean Code and TDD to Python, R, and JavaScript projects I think that to be competitive as an independent consultant is important to manage all steps of software development while keeping track of the latest technological advances that came as open-source options. This allows me to keep low costs on clients while achieving high levels of performance.
