How we work

What to expect.

Mobile app development in Oshawa and Durham Region

We design and build iOS and Android apps for Durham businesses, in Flutter or React Native when one codebase fits, or in Swift and Kotlin when the app needs deep phone features. Typical projects include booking and scheduling apps for service businesses, field apps for trades and logistics teams, customer apps for retailers and internal tools for manufacturers and their suppliers.

Every app includes the server, database and admin panel behind it, and we handle TestFlight and Google Play testing, store listings and launch.

Website development and WordPress design in Durham

We build websites your own team can update, on WordPress, Shopify, Webflow or a custom stack, designed around your services and the people who search for them in Oshawa, Whitby, Ajax, Pickering and Bowmanville. Sites load quickly on phones, are set up for local search and Google Business Profile, and turn visitors into calls and quote requests.

Redesigning an existing site? We map every old address to its new one so the pages that already rank keep their place.

AI chatbots, AI agents and AI receptionists

An AI chatbot can answer questions from your own website and documents around the clock, an AI agent can collect enquiry details and book calls into your calendar, and an AI voice agent can answer the phone when your team is busy. Each one hands over to a person when it should, and we test answers against real customer questions before launch.

Accessibility and privacy, the Ontario way

Ontario's AODA expects many organisations to make their websites accessible, with WCAG 2.0 AA as the standard. We design and test every site, app screen and chat widget against WCAG 2.1 AA, which covers those requirements. For personal information, we follow the principles of Canada's PIPEDA: collect only what's needed, say what it's used for, and keep it secure. For AI tools, that includes choosing where conversation data is stored and how long it's kept.

How a project with us runs

You get one point of contact, a written proposal before any work starts and a weekly review of what has been built. Calls happen on Eastern Time; the development team works from India, so feedback you give in the afternoon is often acted on by the next morning. When all invoices are paid, you own the designs, content and custom code we created for you, and we're happy to sign your NDA first.

We work with businesses across Durham Region (Oshawa, Whitby, Ajax, Pickering, Clarington, Courtice, Bowmanville and Uxbridge) and with companies throughout the Greater Toronto Area and the rest of Canada. Most meetings happen by video, so you get quick answers wherever you are.

FAQ

Questions from Canadian clients.

Do you have an office in Oshawa?

Yes. Our Canadian office is in Oshawa, Ontario, open Monday to Friday, 9am to 6pm Eastern Time. Most project meetings happen by video call.

Do you work with businesses outside Oshawa?

Yes. We work with businesses across Durham Region, including Whitby, Ajax, Pickering and Clarington, and with companies throughout the GTA and the rest of Canada.

Will our website meet AODA requirements?

We design and test against WCAG 2.1 AA, which covers the WCAG 2.0 AA level AODA refers to. We can also audit an existing site and give you a prioritised list of fixes.

How do you handle customer data in apps and chatbots?

We follow PIPEDA principles: collect only what's needed, explain how it's used and keep it secure. For AI chatbots we agree where conversation data is stored and how long it's kept before launch.

How much does an app or website cost?

It depends on the number of screens or pages, the features, any integrations and whether content is ready. After a free call we send a written proposal with scope, timeline and cost, so you know the full price before any work starts.

How long does a project take?

A standard business website typically takes 2–4 weeks, and a larger custom website, online store or web application 4–8 weeks or more. Apps vary more with scope; you get a phased plan with a date for each stage.

Who owns the code when the project is finished?

You do. When all invoices for the project are paid in full, you own the final designs, content and custom code we created specifically for you.
