At STOCOL SAS, I integrated Selligent marketing automation with CRM systems to streamline data flow across business platforms. I also wrote SQL queries, stored procedures, and triggers to automate recurring database tasks.

At STOCOL SAS, I improved database performance through indexing, query tuning, and SQL optimization. My work on Selligent web applications contributed to a reported 30% increase in user engagement, and email campaigns I worked on increased open rates by 25%.

Earlier, I supported CRM users at CDR Asociados and created manuals and knowledge-base articles. At Thomas MTI, I managed MySQL database structures, developed internal projects with MySQL and PHP, and supported application users through GLPI, phone, and email.
