During covid-19, I was in charge of developing a new way to pay totally contactless, on gas stations, which took me to adapt a very large app to use geolocation in order to pay from the app and activate the pump to serve the gas, becoming a real game changer on the retail area specially when nobody wanted to have contact with more people for the risk it meant. Oracle PL/SQL Programming language. Develop Stored Procedures and Functions, at the database, some of them included in JOBS to be executed automatically, especially the ones that are the base for the ETL process running at night for the TABLEAU, SERVER. Developing triggers and packages for database objects that require special treatment when it comes to the DML instructions executed by end users, especially for having LOGS of specific actions executed by users on very specific rows of the database or the kind of actions like updating some fields and required an email to be sent to supervisors or managers in order to check if the change is ok. Experience developing a large and complex manufacturing solution starting from the design, defining ER, taking requirements from product owners(Scrum), using all Oracle tools, this solution is deployed in 5 countries in Central America with one data center in El Salvador, developing KPIS for the whole supply chain, improving production lines performance by reducing the setup time and waste, giving visibility required at the top level of the company in terms of cost prediction, WIP COST, and the factors that impact the P&L being able to take actions before delaying production due dates. I have migrated more than 100 oracle instances from version 8 up to version 18c, becoming an expert Oracle DBA and developer using JDEVELOPER, WEBLOGIC SERVER, ORACLE FORMS, ORACLE REPORTS, RMAN, ETL, DATAPUMP, EXPORT, IMPORT, TOAD, ER TOOLS.
