Junior ML/AI Engineer focused on LLM training, AI systems, and data engineering.

I am finishing a double degree in Computer Engineering and Data Science / Artificial Intelligence at the University of Deusto. My strongest technical direction is AI systems for constrained hardware: native PyTorch training loops, low-VRAM LLM fine-tuning, LoRA/quantization, Triton kernels, benchmarking, and reasoning-model evaluation.

Junior Data Engineer - Lantek
Bilbao, Feb 2024 - Jun 2025

Worked on industrial analytics and ETL pipelines using PySpark, Databricks, SQL, Delta Lake, Docker, Azure DevOps, CI/CD, Git, and Jira.

• Low-VRAM LLM fine-tuning with PyTorch, LoRA, quantization, and Triton.
• GRPO-style reasoning-model training and evaluation.
• Semantic-entropy methods for curriculum design and selective training.
• Systems work in C/C++, Python, CUDA-oriented tooling, and benchmarking.

Native PyTorch training and evaluation stack for GRPO-style reasoning-model fine-tuning on constrained NVIDIA GPUs. It includes manual LoRA adapters, 4-bit model loading, entropy-based selective backpropagation, SENT curriculum support, OOM recovery, Triton kernels, profiling tools, and reasoning benchmarks.

I keep a compact technical portfolio with project case studies for public, private, and academic work:

• Technical portfolio
• GRPO Training Engine case study
• GenAI/RAG Fitness Plan Generator case study
• Rocket League RL Agent case study
• Data Engineering experience

C/C++ client-server project for nightclub event management, built with Winsock, SQLite, and a console-based workflow for tickets, reservations, users, and administrator operations.

• ML Engineering
• Applied AI Engineering
• LLM / GenAI Engineering
• AI Infrastructure / ML Systems
• MLOps or ML Platform
• Data Engineering roles close to ML/data pipelines

Python, PyTorch, Hugging Face tooling, Triton, CUDA-oriented workflows, PySpark, Databricks, SQL, Delta Lake, C, C++, Java, Linux, Git, Docker, benchmarking, and ML evaluation pipelines.
