About Darío

Want to take AI in your company beyond the demo stage? I help businesses integrate Large Language Models (LLMs), AI agents, and automation into their products and processes with production-ready solutions built to last.

I have 6 years of software development experience, with the last few years focused on AI-powered systems: agents that perform real-world tasks, assistants connected to your data (RAG), workflow automation, and model integrations through APIs. I don't stop at prototypes—I design the architecture, integrate it with your systems, and deliver reliable production solutions.

How I can help:

• Integrate LLMs and AI agents into products or internal processes
• Build chatbots and assistants powered by your documentation and data (RAG)
• Automate repetitive tasks and workflows
• Backend and API development with Python/FastAPI
• Full-stack application development
• Business websites, landing pages, and web applications
• Infrastructure setup, deployment, Dockerization, and cloud integrations
• Troubleshooting, debugging, and solving technical issues
• Technical consulting, architecture design, and feasibility analysis

My main stack includes Python, FastAPI, LangGraph, React, PostgreSQL, Docker, Celery/Redis, Laravel, PHP, and Java. I also hold a Master's degree in Cybersecurity, so privacy and security are considered from day one, not as an afterthought.

I work directly and pragmatically: I'll tell you what makes sense to build, what doesn't, and why. Whether you need an AI solution, a full-stack application, a website, infrastructure support, or help solving technical problems, I can help you find and implement the right approach.

Tell me about your project, and I'll propose the simplest solution that effectively solves the problem. I also provide consulting services to assess your project's feasibility within today's technology landscape.
