Native Spanish speaker. Working Proficiency in English. Scored 895 out of 990 on the Test of English for International Communication (TOEIC).

I focus on your relational database schema design and SQL. All from SQL antipatterns, unique and partial indexes, JOINs, nested queries, recursive queries to how to represent SQL code on your ORM of choice.

I was the community TA for the Coursera Startup Engineering class and for the Coursera Machine Learning class. I've also worked for several startups as a remote contractor.

If you need to tackle issues like 'how to ensure we sell a concert ticket (ie. numbered seats) only to one customer given that we have multiple concurrent users trying to buy it at the same time?' or 'how to reference multiple parents for the same database model/table? 'then I might be the right guy for you.
