Thorough analysis of user stories and estimation using story points.

Federico upholds a rare standard among software developers by putting into practice the habit of writing tests before writing code (Test-Driven Development). I've interviewed hundreds of engineers in my career, and I estimate that only 5% of engineers follow this best practice. Federico is very good at setting expectations and skilled at negotiating tradeoffs of time, budget, and scope. He is also wonderfully fluent in both English and Spanish, so fluent that I could not even guess which was his first language.

Did complete the project, not to standard. Was not very responsive and helpful afterwards. Ignored most questions and those that he did answer were very brief and uninformative. Very long and painful process, would not recommend.
