How a Performance Study Changed the Way I Think About Optimization

How a Performance Study Changed the Way I Think About Optimization

I recently read a paper on high-performance computing (HPC), which reshaped my understanding of performance work. I used to think HPC was mostly about having the “fastest algorithm.” Perhaps, the more I delved into the research and my own experiments, the more I realized that HPC is fundamentally about how

Engineering Lessons From Building an LLM PoC: What I Learned Building SheepOp

Engineering Lessons From Building an LLM PoC: What I Learned Building SheepOp

Creating a full transformer implementation and RAG optimizer from scratch provides insights that typical high-level frameworks obscure. Over the past days, I've built two open-source projects—SheepOp, a transformer implementation from scratch, and the LLM RAG Data Structures Optimizer, a production-grade optimization library. The experience revealed several lessons

Retrieval Optimization for RAG: Data Structures That Make Search Fast and Reliable

Retrieval Optimization for RAG: Data Structures That Make Search Fast and Reliable

In Retrieval-Augmented Generation (RAG) systems, inference efficiency only solves half of the problem. The other half lies in retrieval. Dense retrieval models, vector search indexes, and hybrid scoring mechanisms all rely on data structures whose design significantly impacts performance. While many developers focus on model architecture and fine-tuning, the retrieval

LLM understanding

Recently I got an idea during one of the assignments of the master's, what the heck with the LLMs, how those work, how many types are, what is an LLM in fact. Beginning The moment started, and then I saw a YouTube video by Andrej Karpathy, one of

Too Much to Quit: Mi Experiencia Leyendo _Crear Desde Acá

I have read the book Crear Desde Acá from Platzi. When I saw this book on the Platzi Conf I wanted to read it the first time I saw it. This book is amazing, and in advance, this post will be on Spanglish, porque a veces así funciona mi cerebro,
