About Julián

I am a seasoned professional currently focused on Artificial Intelligence, with a particular emphasis on developing innovative and scalable solutions.

For the past 4 years, I have worked as CTO and lead developer at an AI startup company, where I have led the development of a range of deep learning-based services dedicated to the management of hospitals and operating rooms.

My AI experience includes:

**Computer Vision**: I have developed computer vision projects using different versions of YOLO and Transformers, achieving accurate and efficient results in tasks such as object detection and recognition.

**Natural Language Processing (NLP)**: I developed applications using NLTK and later LLM and LMM models for generative and analytical applications.


My technical skills include:

**Programming**: Python, Django

**Databases**: MySQL, SQL Server, Oracle

**Web Technologies**: HTML, CSS

**Environments**: Google Cloud, VPS


In addition to my AI experience, I also have a solid background as a DBA for SQL Server and Oracle and as a Linux systems administrator.

Experience

  • Quantivadata S.L.
    AI Leader
    January 2021 - Today (5 years and 7 months)
    • • Generative AI Strategy and Architecture (LLM & RAG): I designed the implementation of the corporate AI ecosystem (Vision + Generative), building advanced RAG architectures for real-time material verification and validation. I created the end-to-end pipeline by automating the generation of multimodal embeddings with CLIP to align visual and text data, their indexing in vector databases, and hallucination mitigation, ensuring maximum technical accuracy and strict compliance with healthcare data governance.
    • • Productization and Deployment (MLOps & Cloud): I conceptualized and developed the conversational voice interface for healthcare personnel, inspired by efficient intelligent assistant architectures (Amazon Alexa style). To this end, I integrated and optimized local Small Language Models (SLMs) and those from the Gemma family, enabling linguistic processing at the edge (local) to issue and receive verbal instructions with critical latency, without the need for physical contact in the operating room.
    • • Inference Optimization and High Availability: I created the complete model lifecycle (CI/CD, Docker, monitoring) under scalable microservices and RESTful API architectures. I successfully led the system's transition from the pilot phase to its final productive implementation in hospital environments and Cloud infrastructure.
    • • Data Engineering and Automation (Computer Vision & NLP): I led the deployment of computer vision (YOLO, PaddleOCR) and language models in critical environments, optimizing memory and computation usage to ensure ultra-low response times (inference <400ms in vision). I automated key operational workflows for ingesting and digitizing complex documentation and implant cards with over 98% accuracy.
  • Mölnlycke Health Care
    Service & Technology Development Manager
    February 2006 - December 2020 (14 years and 10 months)
    • • Large-scale Digitization: I led the massive implementation of EDI systems connecting over 50 public hospitals, automating critical processes and reducing processing times by 60%.
