About

I like systems that are simple and dependable.

I'm a full-stack developer focused on Node.js, currently a Senior AI Engineer at FlyRank (part of the 10x.ai ecosystem). Over ~3 years I've built production systems where the job is turning messy inputs into clean, reliable outputs that teams can actually depend on.

Most of my work lives in automation and scalable content infrastructure — writing tooling that removes repetitive work, keeps pipelines running, and connects services and data sources across generation, localization, publishing, and optimization.

I care about clear inputs and outputs, strong logging and observability, and failure handling that makes jobs resilient — so they scale from "run it once" to "run it daily in production."

Selected Work

Most of my production work is proprietary, so here's the impact and how it was built rather than the raw code.

Automation

Streams — modular pipeline builder

A drag-and-drop system for assembling content pipelines from modular blocks — flexible workflows non-engineers can compose.

  • Co-developed the logic for composing generation, localization, publishing, and optimization steps.
  • Turned rigid one-off scripts into reusable, configurable building blocks.

Off the Clock

When I'm not shipping code, I'm making noise and pictures.

Bass in Lepra

I play bass guitar in the metal band Lepra. Loud, fast, and a lot of fun.
