Web Design & Development for the GTA
Custom websites, web applications, and API development for Toronto-area businesses, without agency overhead in the invoice.
I'm Corby Wenzelbach, a web designer and developer based in Belleville, and I work with companies and organizations across the Greater Toronto Area. Over the past decade I've built business websites and web applications, and worked on the membership platforms national associations run on.
If you need web design and development in the GTA, or API development in Ontario, you've found someone who does both.
Closer to home, I also work with businesses in Oshawa and Durham Region, Whitby, Belleville and Quinte West, and Kingston.
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's fast, clear, and built around how people choose a service provider. Most of my Toronto-area work falls into a few categories.
Business websites
For GTA companies that compete on more than price.
Ecommerce platforms
Payments and inventory you can run yourself.
Web applications and membership platforms
Built around your workflow, including renewals, chapter pricing, and member directories for associations.
API development and integrations
Payment, CRM, and membership systems that share data without manual exports.
SEO and performance
For sites that deserve more traffic than they get.
I've worked on bilingual platforms in English and French.
National associations and Ontario organizations often need every page, news item, and resource in both official languages. On ACSESS and the Canadian Nutrition Society, both languages run through the whole CMS rather than being added afterwards, and staff manage the English and French content themselves.
API Development and System Integration in Ontario
Plenty of GTA businesses are held back less by their website than by systems that don't share data cleanly. That's where I spend a lot of my time: building APIs that connect payment processors, CRMs, membership databases, and the third-party tools you already use.
In practice that means custom REST endpoints with proper authentication and versioning, Stripe and PayPal integrations, webhook handling so your system reacts as soon as something happens elsewhere, and data syncing between platforms that weren't built to work together. I've done this for national organizations moving members, payments, and communications across several services at once, and it keeps running without anyone having to think about it.
Hiring a Toronto Agency or a Freelance Developer
Agencies have their advantages, and for some projects they're the better choice. I'm one person, so I take on fewer projects than an agency can.
An agency gives you
- Capacity and a team
- Someone to call when your main contact is on holiday
- Large simultaneous rollouts across several brands
Working with me gives you
- Almost all of the budget going into design and development, rather than account management, project coordination, and downtown office space
- The person you speak to in the first conversation writing the code, so nothing gets lost being relayed through a third party
- Decisions that happen in one message instead of three meetings
I also work for agencies and design studios.
Agencies and studios bring me in as a subcontractor for backend development, integrations, or complex builds their own team isn't set up for. I work under your brand, follow your process, and stay out of the client relationship unless you want me in it.
Does a Toronto Business Need a Toronto Developer?
For most projects, no. What matters is whether the person building your site is any good, and whether you can reach them.
Almost none of the work happens in a room together. If your project does need someone on site regularly, hire locally, and I'll tell you that rather than take on a project I'm the wrong fit for.
Every GTA site and application launches with the technical side of search done, including structured data that tells Google what your business is and where it works. For budgeting, read what drives the cost of a website.

Questions From GTA Clients
Can you handle API work and system integrations?
Yes. On CIM | Chartered Managers Canada, a Credly integration issues members a digital badge as soon as they join or renew. On the RTDNA Canada Awards, entries upload to Amazon S3 and are transcoded through Zencoder so judges can play them in the browser. For payments I've worked most with Stripe, Moneris, and PayPal, and if a platform has an API, I can work with it.
Do you work with associations and non-profits?
Yes, and it's some of my most established work. I've worked on the platforms behind national associations including CIM | Chartered Managers Canada, ACSESS, the Canadian Condominium Institute, and the Canadian Nutrition Society, covering online applications and renewals, member pricing, directories, and Stripe payments with receipts. Each one has a case study in the portfolio.
What happens to my project if you're unavailable?
It's a fair question to ask any freelancer. The domain, content, and code are yours, and the code is documented and kept in Git, so another developer could pick the project up. If you ever need to move on, you take everything with you.
Can you build from our agency's or designer's designs?
Yes. If your in-house team or another agency has designed the site, I'll build it to the approved designs and handle what sits behind them, such as the CMS, payments, and integrations.
Which parts of the GTA do you cover?
All of it: Toronto, Mississauga, Brampton, Markham, Vaughan, Richmond Hill, and east through Pickering, Ajax, Whitby, and Oshawa, where I grew up.
Will you come to Toronto for a meeting?
Yes, if meeting in person would move the project along, though most projects don't need one.
