Pedro "Axefield" de Castro Davila
Senior systems engineer and founder behind Truligon with 20+ years of crafting user experiences. I design systems that adapt, learn, and evolve—building AI tools that anticipate needs and creating interfaces that feel intuitive before users even touch them.

Model Context Protocol server that structures complex reasoning into sequential stages. Enables AI systems to break down problems methodically through progressive, stage-based problem solving.
Computational physics project exploring sonoluminescence—modeling the complex multi-dimensional dynamics of bubble collapse and photon emission in TypeScript.
Production-ready TypeScript implementation of Merkle trees. Supports multiple hash algorithms (SHA-1, SHA-256, SHA-512, RIPEMD-160, Whirlpool, MD5) with proof generation and verification.
JavaScript application demonstrating practical web development, clean architecture, and attention to detail for functional, maintainable applications.
Two decades of crafting user experiences has taught me that great design is invisible. It anticipates needs before they're expressed. I specialize in creating interfaces that feel intuitive, systems that scale gracefully, and experiences that users remember.
The best systems are invisible until you need them. Then they feel like they were built for you. I combine deep technical understanding with a focus on user experience, creating tools and platforms that work and anticipate what you need before you ask.
