PHP senior developer and occasional Microsoft Excel instructor. On Codementor since October 2018 to help end users and developers. I like to explain how things work and teaching in a friendly way. I'm able to speak English but I'm not fluent.

I work as a Web Developer using PHP and databases like MySQL, PostgreSQL and Oracle. I also have very interest in Microsoft Excel features such as Pivot Table, Validation Rules and Conditional Formatting, I've worked as Excel Instructor for 10+ years. I'm from Brazil, my English is intermediate/advanced but not fluent. I like helping people resolving problems and creating solutions that work well and simple. Graduation Degree in Computer Science since 2007.

Fernando is good at explaining things as he goes and was able to help me fill in a few gaps in understanding that I had. He's very quick at trying various methods to find solutions, if the first solution was not successful. Very friendly and easy to talk to!
