02 // Engineering Profile

Engineering Profile

My work sits at the intersection of web applications, developer tooling, and hardware integration. I like systems that are clean enough to maintain and complex enough to be interesting.

01

Software Engineering

Designing and building full-stack applications with an emphasis on maintainability, clear boundaries, and pragmatic architecture.

02

Full-Stack Systems

From React frontends and Laravel backends to async Python APIs and Rust tooling — I work across the whole stack when a problem needs it.

03

Developer Tools

Libraries, packages, and internal tools that remove repetitive work: browser extensions, Laravel packages, local-dev infrastructure, and npm modules.

04

Hardware + Web

Browser APIs such as Web Serial, WebUSB, and Web Bluetooth used to connect web applications to vending machines, kiosks, and custom devices.

05

Open Source

Public libraries and starter kits with real documentation, package distribution, and versioned releases.

06

Experimentation

Game prototypes, UI experiments, and small utilities that keep my curiosity alive and often turn into production tools.
