Yeison Pena
Profesional Review
Hi, I'm Yeison, the person who makes the magic on the backend side of the application. I've been working using PHP and MySQL for over 6 years. My top priority is data security and fast response, that's why I do my best to keep optimizing our backend scripts and queries by performing multiple tests and reviews until we get the desired results to exceed our client’s expectations.My passion is backend scripting, but I've been also working as a Senior network engineer for more than 10 years, which is useful when we find a potential client who doesn't have an IT team or employee and requests us to design or improve their server environment where the application will be hosted. This means we can also take care of the application availability, load balance, firewall policies, and data backup/recovery.
