I scope, build, and ship projects end-to-end as a sole developer, from technical planning through deployment, performance optimization, and ongoing maintenance. Contentful Certified Professional.

Outside client delivery, I'm investing in Linux fundamentals, self-hosted infrastructure, and a local AI stack — here's what I'm actively building and tuning right now.
I've been spending a lot of evenings testing local models with Ollama on my home workstation. It's been a fun mix of trial and error: figuring out which models feel useful in real coding sessions instead of just benchmark runs.
The goal is simple: keep a setup that feels fast, practical, and private when I need it. Local models now sit beside my cloud tools so I can choose whatever fits the task best in the moment.
I'm moving my day-to-day setup over to Arch Linux so I can better understand the system layer, not just the app layer. It's been challenging in a good way, and I've learned a lot by fixing things myself.
At the same time, I'm building a small self-hosted server for side projects and experiments. I'm documenting everything as I go so it's repeatable, secure, and easy to maintain long-term.
Production client work — e-commerce storefronts, custom CMS themes, and platform migrations shipped end-to-end.
Migrated a WordPress portfolio into a 14+ page Shopify storefront and built a custom ring builder for stone, band, and size configuration. The site now supports 200+ SKUs and serves 500+ monthly visitors, with ongoing iteration over a 2+ year engagement.

Rebuilt a legacy HubSpot theme into a custom 8-page implementation with reusable HubL modules and CRM-connected forms. The migration improved maintainability and delivered 90+ PageSpeed scores with a 30% load-time improvement.

Built collection layouts and custom product modules for a vintage gaming storefront. A 400+ item JSON migration standardized catalog data and removed manual formatting bottlenecks while improving discoverability with technical SEO updates.

I'm a Toronto-based full-stack JavaScript developer focused on building clean, reliable sites for e-commerce and agency clients. Most of my work is in Shopify, HubSpot CMS, and WordPress, with React/Next.js frontends and Node.js backends.
Before tech, I spent nine years leading culinary teams, which taught me how to stay calm under pressure, communicate clearly, and deliver on deadlines. I'm a George Brown Computer Programming and Analysis grad, a Contentful Certified Professional, and I build day to day with JavaScript, TypeScript, Docker, and modern AI-assisted workflows.
I'm currently open to full-time roles in the Greater Toronto Area, including hybrid and on-site opportunities.
Have a project in mind, a role to fill, or just want to say hello? I'm always open to new opportunities and interesting conversations.
I typically respond within 1-2 business days.
