Products Our Engineers Have Built

Through dedicated projects and team extensions, our engineers have shipped production mobile apps for these companies.

Mobile Is All We Do.
That's Why We're Good at It.

DEVSFLOW is a focused mobile studio (iOS, Android, and React Native) operating from Montreal and Toronto. Every engineer ships mobile code daily. That focus means faster delivery, fewer bugs, and apps that perform where it matters: spotty connectivity, strict compliance, and hospital-grade reliability.

How We Work With You

Two engagement models, both built around how technical teams actually operate. No black-box handoffs, no surprises at demo day.

Custom App Development

End-to-end delivery from architecture to App Store. We own the full mobile stack so your internal team stays focused on backend and business logic.

  • Product scoping and technical architecture review
  • UI/UX design with interactive prototypes
  • Native or cross-platform build (Swift, Kotlin, React Native)
  • CI/CD pipeline setup and automated testing
  • App Store submission and post-launch support

Best for: New products, legacy app rebuilds, or MVP-to-production transitions.

Team Extension

Senior mobile engineers embedded directly into your existing workflows. Your repo, your standups, your sprint cadence. No ramp-up friction.

  • Engineers matched to your tech stack and domain
  • Same-timezone collaboration (EST/CST)
  • Integrated into your Jira, Slack, GitHub, and CI tools
  • Weekly progress syncs with your engineering lead
  • Flexible scale: add or reduce headcount per sprint

Best for: Teams behind on roadmap, pre-launch surges, or filling a senior mobile gap.

From Call to Codebase in Days, Not Months

01

Discovery Call

30-minute call with a senior engineer. We listen, ask hard questions, and tell you honestly if we're the right fit.

02

Scope & Proposal

Within one week: a clear technical scope, timeline, and fixed-price or time-and-materials proposal. No surprises.

03

Build & Ship

Bi-weekly demos, direct Slack access, and working builds you can test on your device from sprint one.

04

Launch & Support

App Store submission, monitoring setup, and post-launch support. We don't disappear after delivery.

Industries We Serve

Domain context matters. We bring mobile expertise to the industries where reliability, compliance, and performance are non-negotiable.

Financial Services

Mobile banking, payments, and trading apps built for Canadian regulatory environments.

Workforce & Security

Offline-first field apps for teams operating where connectivity is not guaranteed.

Media & Streaming

Video delivery and content apps optimized for low-latency playback across variable networks.

Healthcare & Research

Biosignal monitoring and clinical data capture apps built to medical-grade reliability standards.

These are our core verticals, but mobile problems are universal. If your industry needs reliable apps, let's talk.

Built With What Works

We pick tools deliberately based on project requirements. Native when performance demands it. Cross-platform when speed-to-market matters.

iOS Android

Languages & Frameworks
