01 // what I do

AI capabilities

🤖 LLMs & AI Agents

Agents and assistants that reason, call tools and act on real business systems, built with MCP and function calling.

📚 RAG & Knowledge

Retrieval pipelines that ground LLMs on company data, with evaluation loops to keep answers accurate.

🎨 Generative Vision

Diffusion models, GANs and conditioning strategies for controllable, spatially aware image generation.

☁️ MLOps & Cloud

Dockerized services, auto-scaling inference and parallel training on AWS (SageMaker, Lambda, ECS, S3).

🧪 Fine-tuning & R&D

Model scouting, fast experimentation and fine-tuning on domain data to get the most out of state-of-the-art models.

🧭 AI Strategy & Leadership

AI roadmaps tied to business value, multidisciplinary teams, and turning complex systems into clear decisions.

03 // who I am

About me

I'm Martí, a Telecommunications Engineer from Barcelona who has been working with generative AI since 2019, long before it was everywhere. I started doing research on GANs for interior design, and that prototype turned into StageInHome, the startup I co-founded and where I led all the AI for almost five years.

Along the way I've trained diffusion models, built production APIs and set up auto-scaling AI services on AWS. Later, as AI Lead at Napptilus Tech Labs, I led a multidisciplinary team shipping LLM and RAG solutions for clients in many different industries.

Today I'm AI Lead at REVEL, where I define the AI strategy and build agents and AI infrastructure that people actually use every day. What I enjoy most is finding the simplest AI solution that has a real impact, and then making it reliable in production.

When I'm not building, I write about AI on my blog.
