My History,

I am Juan Contreras, a certified professional (Oracle Forms – Oracle Cloud - PLSQL - SQL - DBA) in addition to Oracle Data Integrator (ODI) support and development experience working.

I consider myself as an unstoppable learner, skilled problem identifier and troubleshooter in a range of IT environments with certified knowledge of Oracle Cloud Infrastructure (OCI); Bilingual English-Spanish with verified employment history.

My first job in IT development allowed me to gain experience as an Oracle Forms PLSQL developer, and during that time I learned to build complex PLSQL objects in all phases of SDLC; in addition, I had the opportunity to work as an Oracle instructor for IT students willing to get the Oracle PLSQL certification. I keep teaching what I learned and researched through my YouTube channel

After my experience as a Developer and instructor, I had the chance to work as an Oracle & MSSQL Database Administrator in critical environments inside several companies, keeping Database availability, making recurrent reviews of the security vulnerabilities, and creating backup & recovery strategies, along with automated procedures in different scenarios.
In a nutshell, I am a self-motivated DBA and Developer (PLSQL - ODI) who greatly enjoys learning about cloud environments and DevOps, it is also vastly rewarding for me to see my final code working in production environments with efficiency and quality.

Other than my work history and technical skills, I am just a thankful guy living in a beautiful family, among people of a great country within
an amazing community, so I cannot stop to say thank you God for that!
