Data analyst and software developer driving automation and efficiency.
ChileWhat I'm looking for
I am a results-driven data professional and software developer with over 3 years of experience across ETL development, process automation, and master data management. I specialize in building scalable automated solutions that improve operational efficiency for multinational clients.
At Enex (Shell) I managed master data for nationwide retail operations, developed complex SQL procedures for bulk price loading, and led data migration efforts for a POS pilot. At Samsung I built robust ETL processes and automated commercial reporting, cutting manual effort dramatically.
Technically, I am proficient in SQL Server, C#, and Python, and I work with tools such as SSIS, Power BI, PostgreSQL, MongoDB, and Azure DevOps. I have delivered solutions including C# integrations to parse XML invoices, automated anomaly alerting, and ticketing systems for internal case management.
I am currently pursuing a B.S. in Computer Science Engineering while continuing to apply practical software development and data engineering skills to solve business problems and drive data-driven decisions.
