( Engineering practice )From protocol specs to production URLs

I build software from raw specs and rough sketches to production infrastructure.

I own the full build lifecycle—data structures, network logic, UI systems, and reliability.

How I work
( Along the way )

A few places where I spend my time.

Hands working on a tablet with a stylus
01 / Prototype

Flow before polish.

Technical cabling and electrical systems
02 / Runtime

DNS, routing, observability.

Abstract light reflected through textured glass
03 / UI

State made visible.

( Things I've made )

Out in
the world.

A zero-query naming system, domain registry, DNS management panel, expense splitter, and API shield.
