Resume
Senior full stack engineer. I design integration layers, data paths, and the contracts between services—usually against systems that already exist and cannot be rewritten. Recent work is under NDA. This document and the case studies on lizanlycan.com are the public record.

Magna Cum Laude. Thesis: an API for a generic certification process on Ethereum.
Personal
Curiosity is the through-line. I was trained as a systems engineer and I still read physics and astronomy the way other people read changelogs: to keep a model of how the world is put together.
People who have worked with me tend to mention the same qualities: investigative, dedicated, and unwilling to leave a half-understood path in production. The alias LizanLycan is the same person — just the name I used in communities before the title caught up.
I live in Valencia. The city at dusk on the banner is not decoration; it is where the work is done. I work remotely and I keep the personal side of the page separate from the systems record on purpose.

Classic and modern physics
Models first. The quiet circuit geometry on the west of the banner is the personal half of the same instinct I bring to architecture.
Astronomy
Scale, instrumentation, and sitting with incomplete data until a structure appears.
Data science
How a graph, a pipeline, or a label stream becomes something a model can trust.
Blockchain engineering
Contracts, identity, and the boring path that has to hold after the demo.
