Spain

Message

At INDRA (MINSAIT), I supported the design, maintenance, and optimization of relational databases as a database engineering intern. I also developed and ran SQL queries to extract, analyze, and assess data.

I collaborated on identifying and resolving data-related incidents, and documented data structures and procedures.

At GOLDEN PARK, I provided N1 technical support in English, handling user-reported issues and escalating bugs or server outages to higher support and development levels.

I'm studying a Higher Degree in Multiplatform Application Development at ILERNA and currently pursuing a Psychology degree at UNED. My studies include programming, web and mobile development, databases, application testing, and security.
