About
Enterprise engineer. Business brain.
By day, I'm a Lead Software Engineer at Ferguson Enterprises, where I architect solutions across 500K+ products, mentor engineering teams, and own the pages that millions of customers see every month. With a business management degree and a Codesmith engineering immersive under my belt, I don't just write code — I understand why we're writing it.
When I take on consulting work, I bring all of that with me. I ask the hard questions before writing a single line of code. I'll push back if your plan doesn't make technical sense. And I'll build something that actually works — not just something that looks good in a demo.
Services
What I can do for you.
Custom Web Apps
Not a template with your logo slapped on. I build full-stack applications from the ground up — the same React, Node, and TypeScript stack I use to serve millions of users daily. Your app will be fast, maintainable, and built to grow with you.
Get startedBusiness Automation
If your team is copying data between spreadsheets, manually sending follow-ups, or doing anything repetitive that makes them want to quit — I can fix that. I build automation that saves real hours every week and pays for itself fast.
Get startedTechnical Consulting
Not sure if your tech stack is holding you back? Need someone to gut-check your architecture before you invest six figures? I'll give you straight answers on what's working, what's not, and what to do about it. No jargon, no filler.
Get startedWebsite Design
Your website should be your hardest-working employee. I build fast, modern sites that look great, load instantly, and actually convert visitors into customers. If your current site takes more than 3 seconds to load on mobile, we need to talk.

E-Commerce Performance Architecture
Redesigned the review and rating system for a large-scale e-commerce platform spanning 500K+ products. Separated static and dynamic data paths to eliminate redundant API calls, and replaced an underperforming cache (less than 10% hit rate) with an Apollo-based solution. The kind of project where shaving 100ms matters — because it's multiplied across millions of monthly sessions.
High-Traffic Frontend Platform
Architect and own the top-of-funnel experience for a major e-commerce platform — home, product listing, and category pages that are the first thing millions of monthly visitors see. Built on React with Apollo/GraphQL for data, Node on the backend, and DataDog for real-time performance monitoring. When these pages slow down, revenue drops. They don't slow down.
Scheduling & Booking System
An automated appointment scheduling system that reduced no-shows by 40%. Includes SMS reminders, calendar sync, and a client-facing booking portal.
React Fetch Tree
Open-source Chrome DevTools extension I built for debugging React application performance. Visualizes component trees and maps API call patterns so developers can spot bottlenecks instantly. Built with custom Babel parsers, Jest and Enzyme testing, and Visx for dynamic data visualization. Published to the Chrome Web Store.
