Engineering rigour, for every audience
I'm a Senior Web Engineer with 9+ years building high-scale frontend systems across Australia, the UK and India. I specialise in the modern Angular ecosystem — v20 signals, Nx monorepos and NgRx — and I obsess over the things users never see: performance budgets, accessibility, and test coverage that actually holds.
For companies that means enterprise architecture and measurable outcomes: 35% faster builds, 400ms off First Contentful Paint, 90%+ coverage. For small businesses and tradies it means that same rigour applied to a fast, reliable site that brings in work. I also build in Next.js, Astro and Nuxt when the project calls for it.
My working process
I start with your brief, users and goals — mapping requirements before a line of code.
I plan structure, state and performance budgets so the build scales instead of buckling.
Clean, tested, accessible components shipped in small, reviewable increments.
CI/CD, zero-downtime releases and monitoring so it stays fast long after launch.
Problems, solved
Real engagements from 9 years of shipping. Each one framed as problem → approach → result.
Winning Group
↗A legacy e-commerce frontend with slow builds and code duplicated across teams.
Architected an Nx monorepo, led the industry-first migration to Angular v20 with signals, and built a custom UI library to replace legacy dependencies.
35% faster CI/CD, 50% more code reuse, 60% smaller bundle and 400ms off First Contentful Paint.
Direct Line Group
↗Fragmented Angular repositories with redundant API calls and slow, risky deployments.
Standardised NgRx state management across 5+ repos and hardened CI/CD with automated governance and pre-commit checks.
30% fewer client-side API calls, deploys cut from 45 to 12 minutes, and 100% zero-downtime releases.
SRT Marine
↗Marine control systems needed real-time data rendering without dropping frames.
Solved complex Unity iframe integration and built a shared module library used across three product lines.
Steady 60fps real-time rendering, 40% faster feature delivery and 85% test coverage.
QBurst
↗Clients needed to explore million-row datasets interactively.
Built D3.js analytic dashboards on an Angular + NestJS stack for projects with $200k+ budgets.
1M+ rows visualised with sub-second latency, giving clients real-time insight.
TopDel Renovation
Visit site ↗A custom joinery maker with genuinely premium work and no site to prove it — homeowners comparing makers had nothing to judge the craft on before ringing.
Built a photography-led Astro site around the completed-project gallery, with every image run through a Sharp responsive pipeline, LocalBusiness and FAQ schema, and a quote form as the low-friction next step.
Live on the client’s own domain: a two-page static build with inlined critical CSS, responsive WebP throughout, and the gallery — not the copy — doing the selling.
The tools I reach for
Depth in Angular, breadth across the modern web — labelled by real proficiency, not vanity.
