Mariano is a great person to work with. Always communicative, considerate, and helpful. He cares about attention to detail and has a fantastic grasp on systems-thinking. I'd recommend him for any type of Python work, especially in distributed computing and backend web application development.
Mariano is the best person you can have on your company/team, and it has been a great experience collaborating with him on a day by day base, providing advance coding skills from years of experience as a software engineer.
We highly recommend him for any project, simplex or complex. His courtesy, experience and skill set are a blessing.
We also enjoyed working with Mariano on very specific projects thar required some creative thinking and high throughput. We found him to be a very pleasant and diligent person and worker.
I worked with Mariano for couple of projects already and he is the best that you can find to work with, he is good at his job, fast learner, great attitude. He will always be my first choice for the new projects that I have coming.
Thank you Mariano for a great job!
