I'm Jeremy — a frontend engineer who treats every interface like a composition: a few strong elements, an honest grid, and nothing that doesn't earn its place.

For over eight years I've designed and built user interfaces for product teams, from early-stage startups to large-scale platforms. I work where design and engineering meet — translating systems of type, colour and layout into resilient component libraries, and shipping applications that load quickly, read clearly and work for everyone.

My toolkit is modern — TypeScript, React, Vue, and a deep respect for plain HTML and CSS — but my principles are old: clarity over decoration, structure over trend, and craft in every detail.

Clarity

Interfaces that explain themselves. Semantic markup, legible hierarchy.

Economy

Small bundles, fast paint. Every kilobyte is accountable.

System

Reusable parts, consistent rules, scalable design tokens.

02Elements

The basic
shapes of
my craft

Like the Bauhaus workshop, every discipline is a primary element — combined deliberately to build something whole.
