R and Julia Programming with Markov Chain Models Optimization Expert

Hello, I am hiring a programmer to work with both R and Julia programming, using Markov Chain Models. I have existing code that has been used in R, but need some optimization to get it working in Julia. I am looking for someone experienced in both discrete and continuous Markov Chain Models. The successful freelancer must have the expertise and the confidence to apply their knowledge to the project. I am open to ideas for improving my existing code so that it works for both R and Julia and I am hoping to find the perfect fit for this project.
