I am a Telecommunications Engineer and a Specialist in Data Science and Analytics with a strong focus on Artificial Intelligence and process automation.

I have experience as a Web Developer and Data Analyst, where I built data-driven solutions to support business decision-making through dashboards, data visualization, automation, and database management.

I also work as an LLM Trainer, focusing on quality evaluation, reasoning, alignment, code analysis, prompt engineering, and validation of AI-generated solutions in real-world environments.

My background combines programming, analytics, networking, and AI. I work with Python, SQL, HTML, CSS, JavaScript, Power BI, Excel, machine learning, APIs, n8n, and chatbots.

I am especially interested in roles where I can design and integrate technology solutions that improve processes, automate tasks, and enable better decisions through data and AI.

I am based in Bogotá, Colombia, and I am open to remote opportunities where I can contribute with technical problem-solving, analytical thinking, and practical AI implementation.
