About Nicolás

I am a software developer specializing in LLM-based systems and data-oriented solutions. I help companies design and implement intelligent agents, RAG systems, and automations that connect multiple information sources to solve real business problems.

I primarily work with Python and TypeScript, building scalable APIs, backend services, and data pipelines. I have experience developing machine learning models for classification and analysis, as well as integrating AI systems into production environments, ensuring they are robust, measurable, and easy to maintain.

I focus on delivering practical, production-ready solutions, from rapid MVPs to more complex systems. If you need to automate processes, improve your data utilization, or implement LLM-based agents that actually work, I can help you achieve it efficiently.
