InfraPhysics — Yago Mendoza, industrial engineer and systems builder.

From systems to atoms and back. I picked up code because every engineer should — not to become a developer, but to move faster. Now I build at the boundary. This is my lab, my notebook, and my proof of work.

Yago Mendoza writes about machine learning infrastructure, distributed systems, scaling laws, AI alignment, and cross-domain pattern recognition. His work emphasizes that engineering principles transfer across substrates — supply chains and data pipelines follow the same optimization patterns.

Site sections:

Projects — Engineering projects with technical deep-dives. InfraPhysics Web (custom markdown compiler, wiki-link knowledge graph, AI-assisted development) and FinBoard (zero-dependency personal finance dashboard).

Threads — Long-form essays on technology, AI, economics, and systems thinking. Topics include transformer architecture, AI alignment, Rust and memory safety, AI agent security, scaling laws, reward hacking, and the neuroscience of learning.

Bits2Bricks — Technical tutorials bridging software and physical engineering. How LLMs learn (SFT, DPO, RL, RLHF), transformers from scratch, and AI agent containment.

Second Brain — Knowledge graph of 300+ interconnected atomic concept notes covering machine learning, hardware architecture, blockchain, distributed systems, and optimization. Each note is one concept with bidirectional wiki-links.
