Description

Senior Engineer specializing in applied AI, process automation, and cloud infrastructure. I help companies transform manual tasks, scattered knowledge, and operational flows into automated AI systems.

I work with OpenAI, LangChain, RAG, n8n, Make, Python, FastAPI, Node.js, Angular/React, Docker, Kubernetes, Terraform, AWS, and Azure to build real-world solutions: internal agents, email and CRM automation, documentation assistants, lead classification, report generation, API integrations, and business workflows.

My focus is not on creating AI demos, but on useful production systems: clear architecture, security, scalability, traceability, and automations that reduce manual work from the first month.

I have worked on projects for companies like Inditex, Getronics, and the Prado Museum, participating from technical definition to development, cloud deployment, and go-live.

RAG / Private GPT on internal documents and knowledge
n8n, Make, and API-connected workflows
Python, FastAPI, Node.js, and backend architectures
Cloud, DevOps, Docker, Kubernetes, Terraform, and CI/CD

I am looking for projects where AI, cloud, and automation are applied to real problems: reducing repetitive tasks, accelerating operations, improving support, organizing internal information, and creating more efficient systems.

David has been a key player in the entire project. He doesn't just program; he understands the complete vision and turns it into a solid and well-structured system. He always thinks about scalability, real automation, and doing things logically and orderly. Working with him gives me peace of mind because I know that what we are building has a foundation and a future.
