Web apps & sites

Custom web applications, built around your data

When your data needs a front end (a client portal, a marketplace, an internal tool or a business website), I build that too. As a custom web application developer in Montreal, I start from the data, so what I build fits how your business actually works.

Who this is for

Businesses that have outgrown spreadsheets and email, or need a website that actually brings in work.

  • Clients or subcontractors who should see their own information online
  • A spreadsheet-based process that needs to become a proper tool
  • A marketplace or platform idea that needs to be built properly
  • A business website that's slow, outdated or invisible in search

Problems a custom web application solves

Processes run on spreadsheets

Shared files with broken formulas, version conflicts and no record of who changed what.

Calls just to ask for a status

Clients phone or email for information that already exists in your system. A portal lets them look it up themselves.

Off-the-shelf software that almost fits

You pay for features you don't use and work around the ones you're missing.

A website that doesn't bring in work

It loads slowly, says little about what you do and doesn't show up when people search.

What I build

Client and subcontractor portals

Secure logins where people see their own jobs, documents, statuses and reports.

Internal tools

Forms, workflows and approvals that replace spreadsheets and keep a clean record in your database.

Marketplaces and platforms

Listings, accounts, search, messaging and payments, built to grow.

Business websites

Fast, bilingual and search-friendly, so people find you and understand what you do.

Connections to your data

Apps that read from and write to your existing database and reports, instead of creating another silo.

Hosting and support

Set up properly from day one, with maintenance and updates when you need them.

Recently delivered

A few recent projects, described without client names.

An online marketplace

A two-sided marketplace with user accounts, listings, search and a back office for the owner to manage it all.

Business websites

Websites for small companies, built to load fast, explain the business clearly and rank in local search.

How a web project works

  1. Talk

    You explain who will use it and what they need to do. I ask about the data behind it.

  2. Scope

    I sketch the screens and the data model and write down what the first version includes.

  3. Build

    Working versions early and often, so you can click through and give feedback as it takes shape.

  4. Launch and support

    Go-live, monitoring, and changes as your business grows.

Web apps and sites: common questions

What technologies do you use?

Mainstream, well-supported tools such as React, Node.js, SQL Server and PostgreSQL, hosted on platforms like Netlify or Azure. I choose them for long-term maintainability, not trends.

Can the app connect to our existing database or ERP?

Yes, that's usually the point. The app can display live data from your existing systems and write back where it's safe to do so.

Can the site or app be bilingual?

Yes. English and French are built in from the start, which matters for any business in Quebec.

Who owns the code?

You do. The source code, accounts and documentation are yours.

Do you maintain the app after launch?

Yes, ongoing support is available. If you'd rather hand it to your own team, I document it so they can take over.
