Senior frontend engineer and team lead building dependable products across web, native, and AI, from the first architecture decision to the last production detail.
I work where ambitious product ideas meet messy technical reality. That means shaping architecture, creating the systems teams build on, and staying close enough to the code to ship the difficult parts.
Across fintech, commerce, edtech, and healthcare, my bias is consistent: make complexity legible, make quality repeatable, and leave the product and team stronger than I found them.
Three recent builds. Different constraints. The same standard of ownership.
A complete compliance platform for an Australian disability-services provider, spanning an admin dashboard, worker mobile app, and marketing site. Built from an empty repository while the backend was still moving.
Technical leadership for a live services and commerce marketplace: an 11-person team, a production backlog cleared in two weeks, and three growth-critical capabilities delivered on tight timelines.
A unified authoring product for manual and AI-generated courses, backed by the shared type system that reduced runtime errors by 40% across a fast-moving platform.
From shipping interfaces to defining systems, mentoring engineers, and directing cross-functional delivery. The through-line is simple: ownership that scales with the problem.
