Dhananjaya worked hard on a complex challenge involving a large database of option data which had to be stored and processed using several complex queries, which then had to be made available in R. He displayed a great deal of relevant technical and financial expertise and communicated effectively and professionally throughout the project. I will certainly use him again in future projects.
