Web Design & Development for the GTA

I'm Corby Wenzelbach, a full stack developer based in Belleville who works with companies and organizations all over the Greater Toronto Area. A decade of building websites, web applications, and membership platforms, for clients ranging from neighbourhood businesses to national bodies with thousands of members on the books.

If you need web design and development in the GTA, or serious API development in Ontario, you've found someone who does both. I take projects from the first sketch through design, build, launch, and the technical SEO that gets Toronto customers to your door instead of a competitor's.

Web Design and Development for GTA Businesses

The GTA is competitive, and a basic template is usually not enough for a business that needs to earn trust quickly. To stand out you need a site that is fast, clear, and built around how people actually choose a service provider. Most of my Toronto-area work falls into a few categories.

• High-converting business sites for GTA companies that compete on more than price
• Ecommerce platforms with real payments and inventory you can run yourself
• Custom web applications and membership platforms built around your workflow
• API development and system integrations for Ontario businesses
• SEO and performance work for sites that deserve more traffic than they get

Built for speed and longevity, never assembled in a builder. Faster pages, cleaner markup, better rankings, and integrations that hold up when traffic spikes. When WordPress or Shopify is the right fit, I'll build it there and explain the trade-off.

API Development in Ontario

Websites are only half the story. Plenty of GTA businesses are really held back by systems that do not share data cleanly. That's where I spend a lot of my time: building and wiring up APIs that connect payment processors, CRMs, membership databases, and the third-party tools you already use. Custom REST endpoints, Stripe and PayPal integrations, and data syncing between platforms are all common parts of my work for organizations in Ontario and across Canada.

Why Work Directly With a Senior Developer

Hiring a large agency often means paying for account management and overhead before the build even starts. Work with me and the budget goes into planning, design, development, testing, and launch. You deal directly with the developer responsible for the work.

I have been shipping sites and applications for GTA-based organizations for years. Most collaboration happens online, which keeps the process efficient and gives you senior-level work without unnecessary agency overhead.

Areas I Serve

The GTA is a regular part of my work, alongside businesses across Eastern Ontario.

How I Work

The process won't surprise you, and that's the idea. We talk goals and budget, I tell you what's worth doing, then I design it, build it, and launch it. No mystery fees, no unclear revision process, and no project that drags on past its welcome.

Every GTA site and application leaves with the technical SEO already sorted: clean code, fast pages, a mobile-first layout, proper meta tags, and structured data so Google knows exactly what you do.
