AI Engineer · Federated Learning · Privacy-Preserving Machine Learning

I build AI systems that are not only accurate, but inspectable and reproducible.

Engineering focus

Privacy & security Reproducible evidence Responsible AI
I evaluate what models and distributed updates can reveal—not only what they predict. I favour deterministic pipelines, leakage-aware validation, statistical comparisons and traceable results. I document intended use, limitations and safeguards, especially for privacy-sensitive and medical ML.

About me

  • Computer Engineering graduate from the University of Alicante.
  • Professional experience as an Artificial Intelligence Engineer at NTT DATA, working with Microsoft Azure, Azure Machine Learning, LLMs, the OpenAI API, process automation, prompt engineering and technical documentation.
  • Focused on federated learning, ML privacy and security, computer vision, NLP and responsible AI.
  • I enjoy taking technical questions from experiment design to tested code, interpretable results and clear documentation.

Featured work

Project What I built Stack and evidence
Federated Learning Privacy & Security An experimental study of reconstruction attacks and label inference from gradients and local model updates, including clipping and Gaussian-noise defenses. Python · PyTorch · Flower · CIFAR-10 · ResNet-18 · FedAvg/FedSGD · visual attack and defense comparisons
Chest X-Ray Classification Benchmark A reproducible pneumonia-classification benchmark with explainability, transfer learning, deep embeddings and a framework-independent FedAvg simulation. TensorFlow · MobileNetV2 · Grad-CAM · Random Forest · stratified 10-fold CV · paired Wilcoxon tests · research use only
Valencian GDP Prediction Leakage-aware forecasting of quarterly regional GDP variation from Spanish tweets, engagement signals and lagged economic information. Python · NLP · MLP/LSTM/BiLSTM · expanding-window validation · fold-local preprocessing · Wilcoxon tests
Mini Compiler with Flex & Bison A compiler front end with lexical, syntactic and semantic analysis, nested scopes, static type checking, diagnostics and executable-code generation. C/C++ · Flex · Bison · GNU Make · m2r VM · end-to-end regression suite
