About Javier

I am a Data Analyst and Full Stack Developer specialized in transforming data into useful tools and solutions for business. I help companies understand their information and make smarter decisions through data analysis, clear dashboards, and custom applications. I work primarily with Python and SQL for data analysis and processing, and I develop complete solutions ranging from data acquisition to visualization. Additionally, I design and develop custom websites and applications, focusing on performance, usability, and business objectives. How can I help you? • Data analysis and insight generation • Dashboard creation (clear and actionable visualization) • Process automation with Python • Development of data-driven applications and tools • Website design and development I focus on creating practical, clear, and results-oriented solutions, avoiding unnecessary complexity. If you have data but are not leveraging it, or need a website or digital tool, I can help you turn that idea into something real.
