Hi, I'm Gonzalo.
I work at the intersection of AI and real-world software - helping teams adopt large language models, design thoughtful AI features, and move from demo to production. This site is where I write down what I'm learning so it's easier to share and come back to.
What I focus on
- Applied LLMs: prompting, RAG, tool use, evaluation.
- Fine-tuning and adaptation: SFT, LoRA/QLoRA, DPO.
- Model selection: picking the right model for cost, latency, and quality trade-offs.
- Practical AI strategy for teams and products.
What you'll find on this site
- AI Models - a living reference of the major models.
- LLMs & Fine-Tuning - foundational explainers.
- Resources - white papers, tutorials, docs, podcasts, quick guides.
- Posts - short takes, many of them originally shared on LinkedIn.
