Web platforms built to scale with you. Custom web application development for Canadian businesses and SMBs. From complex dashboards to real-time collaborative tools, we build web platforms that handle millions of users while staying fast and reliable.
Custom web application development is the creation of browser-based software — dashboards, client portals, booking platforms, internal tools — built from scratch around a company's exact workflows instead of forcing them into an off-the-shelf product. TechGuys designs and builds custom web applications in Montreal for Canadian businesses and SMBs, using React, Next.js, TypeScript, and PostgreSQL, from the first discovery workshop through launch and ongoing evolution.
Our answers come from platforms we have actually shipped: AidExpress, a home-care platform that matches families with caregivers through smart matching and secure messaging, and Virtuose Formation, an e-learning platform with cohort management and automated follow-ups. Custom projects typically start around CAD $10,000, with a detailed estimate provided after a free discovery call.

Plania is an AI-powered web application that enables entrepreneurs to quickly create professional business plans, while support organizations (MRCs, economic development services, financial institutions, incubators) can manage and support multiple projects simultaneously. The platform centralizes writing, market analysis, financial forecasting, and collaboration to simplify the planning process, reduce production time, and facilitate access to funding.
Stronger Together is a fitness platform for women that combines video training, gym programs, journaling, and nutrition tracking in one place. The web and mobile apps empower users to reach their health goals with an easy-to-use interface, a comprehensive recipe library, and AI-powered macro calculations—all within a supportive community focused on women's wellness.
Virtuose Formation is a digital platform designed to present and sell training programs with clarity, credibility, and conversion focus. We built an experience that highlights the brand positioning, simplifies course discovery, and helps visitors move quickly from interest to enrollment. The result is a modern web ecosystem that supports both marketing growth and day-to-day operational efficiency.
Aidexpress is a digital home-care services platform that streamlines matching between families, care recipients, and qualified caregivers across Quebec and Ontario. The product needed to support rapid operational growth while keeping a human, reassuring, and frictionless experience for both urgent requests and recurring care. We designed a unified experience that speeds up booking, improves follow-up, and simplifies coordination across every stakeholder.
Samuelsohn is a premium menswear house that needed a modern digital presence aligned with its heritage, craftsmanship, and high-end positioning. We designed an elegant brand-first web experience structured to showcase collections, support commercial goals, and simplify navigation between inspirational content and conversion moments. The result is a high-performance platform that strengthens brand perception and streamlines customer journeys from discovery to action.
We built an experimental web application for Bibliothèque de Laval designed to help users discover the library's diverse services. Through a Tinder-style swipe interface, users express their interest in various activities—from borrowing books and exploring new technologies to renting telescope equipment and accessing digital resources. Based on their preferences, the app recommends additional services they might enjoy. Available on desktop, mobile, and digital kiosks installed in partnership with another company, this platform also provides the library with valuable analytics about user interests.
We completely rebuilt HotellerieJobs from the ground up—a major platform migration for one of Montreal's leading job boards in the restaurant and hotel industry. The challenge was achieving full feature parity: everything had to work from day one with no room for incremental deployment. Applicants create detailed profiles with their experience, while employers post jobs for their various staffing needs. The platform also features API automations that import jobs from external sources, serving thousands of users monthly. AI agents played a significant role in accelerating development, and we continue to scale and enhance the platform post-launch.
A website presents information — pages, articles, product listings. A web application lets users do work: log in, manage data, automate a process, collaborate. If your team runs its operations through spreadsheets and disconnected tools, a custom web application usually replaces that patchwork with one system built for your workflow.
Custom web application projects at TechGuys typically start around CAD $10,000. Cost scales with the number of user roles, integrations, and the complexity of your business logic. We scope it precisely during a free discovery call and give you a detailed estimate before you commit.
Build custom when your workflow doesn't fit existing tools, when per-seat licensing costs grow faster than your team, or when the process itself is your competitive advantage. If a SaaS already solves your problem well, we say so — custom development is an investment that should pay for itself.
We build with React and Next.js on the front end, TypeScript and Node.js on the back end, and PostgreSQL with Supabase for data — deployed on Vercel or AWS. This stack is widely adopted, fast, and easy for any future team to maintain, so you are never locked in to us.
A typical first version takes 10 to 16 weeks at TechGuys: discovery, design, development, QA, and launch, with demos at every stage so you see progress continuously rather than at the end.
Yes. We audit the existing codebase first, then either refactor progressively or rebuild strategically — keeping your business running during the transition. Many of our projects start as rescues of systems built years ago.
Let's discuss your project requirements and explore how we can build a scalable solution for your business.
