About

Building systems that scale,
not just features that ship.

My path into enterprise engineering started with Sitecore — one of the most complex CMS platforms in the industry. Working on it taught me that frontend development at scale isn't just about components and pages; it's about data architecture, rendering strategies, deployment pipelines, and the tradeoffs between them.

Over four years across Accenture, SkillianTech, Eviden, and Vertis Digital, I've worked on some genuinely hard problems: migrating a legacy Sitecore XP + Commerce stack to XM Cloud + OrderCloud while replacing a monolithic .NET/React architecture with a composable Next.js + NestJS system — with zero feature regression and measurably improved performance.

I'm particularly drawn to the intersection of architecture decisions and developer experience. Good architecture should make your team faster, not slower. A well-structured multisite Next.js application, a clean headless CMS schema, or a thoughtful API orchestration layer can compound engineering productivity for years.

More recently, I've been exploring what it means to be an AI-native engineer — not using AI as a shortcut, but as genuine augmentation. From architecture discussions with Claude to GitHub Copilot for synthesis, to local LLM experimentation with Ollama. The engineers who figure out how to work with AI as a pair programmer will build significantly more than those who don't.

Case Studies

Engineering case studies

Real enterprise projects with real architectural challenges. Each one taught me something about scale, tradeoffs, and what it means to build for the long term.

Headless CMS Migration

Allstate Canada

Live site

XM Cloud migration and headless frontend architecture for North America's leading insurer.

Challenge

Allstate Canada operated a monolithic Sitecore MVC platform that could not support their content team's pace or their engineering team's desire for decoupled frontends. Page performance and deploy cycles were both lagging.

Architecture

Architected a full migration to Sitecore XM Cloud with a Next.js frontend using SSR and ISR strategies. Designed the component library, serialization pipeline, and CI/CD workflows.

Enterprise Search & Personalization

Saudia Airlines

Live site

Headless Sitecore implementation with enterprise search and AI personalization for a national airline.

Challenge

Saudia's legacy platform served millions of monthly visitors but lacked real-time search, user personalization, and the ability to run A/B experiments at scale.

Architecture

Led the headless frontend rebuild using React and Sitecore JSS. Integrated Solr-based enterprise search with faceted navigation and relevance tuning. Implemented Sitecore Personalize for audience targeting.

Adani One

Live site

Unified travel and commerce platform serving tens of millions of users on Sitecore + OrderCloud.

Challenge

Adani needed a unified digital platform bridging airport services, travel booking, loyalty, and retail — all under one content and commerce system with multi-tenant requirements.

Architecture

Implemented a Sitecore headless solution with Sitecore OrderCloud for commerce operations. Designed multisite architecture to serve multiple brand verticals from a single XM instance with shared component libraries.

OnePA (Vertis Singapore)

Large-scale multisite XM Cloud implementation for a major Singapore public authority platform.

Challenge

The platform required managing dozens of content sites under a single governance model, with independent editorial workflows, shared design systems, and strict performance SLAs.

Architecture

Led architecture of a multisite XM Cloud solution using SXA, custom serialization workflows with Sitecore CLI, and a headless Next.js frontend. Integrated Sitecore Search and built NestJS middleware APIs for content orchestration.

Systems thinking

The patterns and tradeoffs I've worked through across real enterprise systems. Architecture isn't about diagrams — it's about decisions that compound over time.

XM Cloud + Next.js

Sitecore XM Cloud as headless CMS driving a Next.js frontend via Experience Edge. Layout Service responses map to component props through the JSS SDK, enabling fully decoupled rendering.

AI Engineering

AI-augmented
engineering

I'm not interested in the hype cycle. I'm interested in what makes me a measurably better engineer — and I've been systematically integrating AI tooling into my workflow since 2022.

The key distinction: AI is most valuable at the right layer of work. Code synthesis for established patterns, documentation generation, debugging hypotheses — these compound significantly over time. Architecture decisions and system design still require deep domain knowledge and human judgment.

The engineers who build more aren't those who resist AI or outsource their thinking to it. They're the ones who develop strong taste for when to use it, and when the thinking needs to be theirs alone.

# my AI workflow

AI handles pattern synthesis

I handle architecture decisions

Together: compounding output quality

GitHub Copilot

Code Synthesis

Primary in-editor AI. Most effective for pattern completion, test generation, and JSS component scaffolding within established codebases where patterns are well-established.

Reduced Sitecore JSS component scaffolding by ~60% on the Allstate migration. Best for code within known, repeated patterns.

Claude (Anthropic)

Architecture & Reasoning

Used for complex architectural discussions, debugging hard problems, reviewing architectural tradeoffs, and generating thorough technical documentation.

Extensively used for XM Cloud migration planning, NestJS service architecture, and writing ADRs (Architecture Decision Records).

Ollama (Local LLMs)

Private Enterprise Tooling

Local model deployment for privacy-sensitive enterprise codebases. Enables AI assistance without external API calls or proprietary code leaving the network.

Deployed at Eviden for internal code documentation generation — no external API dependencies, no client code exposure.

OpenAI API

Custom Tooling

API integration for building custom developer tools, content generation workflows, and GPT-4 capability exploration in CMS and editorial contexts.

Experimented with AI-generated content summaries for CMS authoring acceleration and boilerplate reduction.

Opinions I hold

On AI in engineering

We're 2-3 years from AI being the default pair programmer. The engineers who develop strong AI collaboration skills now will compound their advantage for years.

On composable architecture

Monolith vs microservices is a false binary. Composable architecture at the right layer of abstraction is what scales — and what that layer is depends on your team size.

On author experience

The best CMS is the one your content teams can actually use. Architecture that ignores author experience will always produce poor content quality, regardless of tech.

On performance

Core Web Vitals are not a vanity metric. At enterprise scale, a 200ms LCP improvement correlates directly with conversion — and with engineering credibility.
