William Ray

"Carlos delivered an excellent piece of work. As always, his insight into the different pieces of the overall architecture was invaluable to me.
Carlos created among other things an automated data validation engine, with internal cron processes to validate, monitor and fix wrong data, that also was able to serve reports for me to be able to look at data quality and data distribution over time.
He solved some challenging data match/merging issues with NLP algorithms, to merge the same instances with different names/descriptions/attributes, and set up multithreaded data analysis with the proportional load on parts of the dataset with fewer data.
Finally, he created functionalities to easily import/export single instances or the entire dataset from the API.
Overall, I am extremely satisfied with both the process and the end product."
