App Development Company in Mississauga
DevDec
DevDec is a Mississauga AI engineering and app development company founded in 2012 by Junal Rahman. You hire one studio, at 6 Come by Chance Mews, Mississauga, ON L5N 1J8, not a rotating cast of freelancers. Call (647) 895-3832. Strategy, design, and engineering stay in the same cycle from the first meeting through release.
We also meet clients from Brampton, Oakville, and Vaughan.
How a Mississauga engagement runs
The first meeting is at the studio when the client can travel. Remote work follows. The scope does not change because someone was not in the room for the decision.
A working session, not a pitch
We leave with the user, the job the product has to do, and a written list of what is out of scope. A proposal that skips that list is how a three-month app becomes a nine-month argument.
Design and engineering in the same cycle
The studio does not hand a Figma file to a separate build team. Interface decisions are checked against the data and the release, then changed while the people who made them are still on the project.
The app and the admin it needs
iOS and Android are rarely the whole product. Orders, content, staff roles, and support need a web surface. We name that surface in the first scope instead of discovering it after launch.
A release you can run, then a new quote
The engagement ends with a version the business can operate. The next version is a new scope. If an existing AI-built app is simply stuck, that is Rescue, not a new company engagement.
What the company takes on
One team for the product, the platforms it ships on, and a separate path if an existing build is stuck.
One studio for the product
The people who scope the work are in Mississauga and stay on it through release. You are not introduced to a delivery centre after the contract is signed.
iOS, Android, and web
Cross-platform and native mobile, plus the web platform beside it. Published examples include ImmiTrack, MyHealth+, and Go Rent Me.
AI only when the product needs it
OCR, a model, or an agent is added where it removes a real task. It is not a default layer. SleepGofer and Wellsnap are products where that bar was met. Many apps do not need it.
A different door for a stuck build
DevDec Rescue is a fixed price for an app that already exists and is blocked on auth, data, deploy, or payments. It is not how a new Mississauga product starts.
Shipped products
Apps designed and built by the Mississauga studio.
ImmiTrack
A Canada immigration app with application tracking, a countdown, expert answers, and custom news.
MyHealth+
Cloud storage for health records, with vaccination and appointment reminders, for people moving to a new country.
Total Wealth Tracker
A product that turns net worth, stocks, and real estate into monthly targets against a financial goal.
Go Rent Me
A no-fee rental app that connects tenants and landlords with property search and management tools.
Questions about the company
Is DevDec an app development company in Mississauga, or a remote shop with a local address?
Yes. Clients meet the team at the studio. We also work with people elsewhere in Ontario and Canada, and the office is not a mail drop.
How is this different from the mobile app developer page?
Mobile work is iOS and Android. Hiring DevDec means the same people stay on scope, design, and the web admin that usually belongs in the release.
Do you only build new apps?
No. Custom software covers internal platforms and legacy replacements. Rescue covers a fixed-price repair of an AI-built app. A new product starts here or on the MVP page if the company is a startup shipping a first release.
How long has the studio been doing this?
Since 2012, 14 years, with more than 200 clients and a team of more than 15 people.
