About Carlos

I build scalable AI systems that work in production.

With a background in Physics (Master's in Physics and Mathematics, University of Salamanca), I apply a solid foundation in optimization and statistics to design fast and reliable AI models.

My latest project in numbers:
→ Led a team of 7 engineers
→ AI platform for the insurance sector (Mapfre)
→ +100,000 emails processed per month
→ 96% accuracy in data extraction
→ 65% less manual work

How can I help you?

📄 Intelligent Document Processing OCR, classification, and layout analysis

🧠 Machine learning and deep learning custom model design and training

⚙️ AI Infrastructure and MLOps model and NVIDIA H100 GPU deployment

🚀 High-performance optimization CUDA, Eigen, BLAS, Intel MKL

👁️ Computer vision and image analysis

A bit of my background:

I patented a document classification system by similarity, was the lead developer of the open-source library OpenNN, and have brought AI into production in the insurance, industrial, and environmental sectors.

How I work:

Reliable deliveries. Clear communication. Full autonomy. I adapt quickly, perform under pressure, and stay focused on your goals.

  • Plexus Tech - SmartIndexing
    Tech Lead & AI Infrastructure Engineer

    April 2024 - March 2026 (1 year and 11 months)
    Da Nang, Vietnam
    I was a Technical Lead specializing in Intelligent Document Processing (IDP).

    We used AWS to create an email automation platform in the insurance sector. We used NLP and Machine Learning models to classify and extract specific data from claims and policies.

    We processed around 3,000 emails daily with 96% accuracy, reducing manual effort (HITL) for Mapfre (USA) and Verti (Germany).

    Tech Lead & Machine Learning Engineer
    DIGITAL AND IT
    May 2021 - April 2024 (2 years and 11 months)
    Remote Remote, Mahesana, GJ, India
    I was part of an international team, and my responsibility was to automatically extract data from invoices, medical documents, and contracts using AI models.

    Over time, I was given the responsibility to create a generic extraction model to attract new clients, perform quick demos with their data, and showcase the product's capabilities.

    I was assigned a team of 4 people with no prior AI experience, trained them remotely and in English. We acquired 2 new clients and expanded the product to the USA.

    AI Software Engineer & Data Scientist
    October 2017 - May 2021 (3 years and 7 months)
    Salamanca, Spain
    I joined this startup without knowing how to code. The company invested heavily in me, training me from scratch in programming and artificial intelligence.

    In a short time, I was given significant responsibility. I was in charge of several AI applied projects in engineering and business intelligence. Some of the things I did:

    - Water turbidity prediction system (Acciona Qatar): I developed an AI application for the Ras Abu Fontas desalination plant. The system predicted water turbidity levels, allowing the operations team to anticipate the best time to shut down the plant. It was in production for several years.

    - Automatic license plate detection system: For a Belgian client, I designed and implemented a computer vision system capable of identifying and reading license plates from cars in multiple parking lots, automating access control.
