Luis Machado

I am a Data Analyst & Automation Specialist based in Barcelona, focused on helping companies improve efficiency, visibility, and decision-making through data and automation. My work centers on transforming raw operational data into structured, reliable insights and building automated workflows that reduce manual effort and improve consistency across business processes.

I work primarily with Python and SQL for data extraction, cleaning, analysis, and validation, and I design internal tools and dashboards using Google Sheets, AppSheet, and Google Apps Script. These solutions are often used for reporting, monitoring, forecasting, and operational planning, with an emphasis on clarity, reliability, and maintainability rather than over-engineering.

In addition to analytics and automation, I have practical experience using AWS cloud services to support data workflows and lightweight processing. I use Amazon S3 for secure data storage, AWS Lambda for event-driven automation, CloudWatch for logging and monitoring, and IAM to manage permissions following security best practices. These cloud components are typically integrated with Python-based analytics and internal tools to create scalable and cost-effective solutions.

I am comfortable working with ambiguous requirements and collaborating closely with stakeholders to translate business needs into technical implementations. I value clean logic, clear documentation, and solutions that can be easily understood and maintained by others. All work is handled with strict respect for data privacy and confidentiality, and projects are delivered with a strong focus on practical business impact.
