How We Work With You

You pick the model. We plug in and start shipping.

01

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.
02

Team Extension

Senior mobile engineers embedded directly into your existing workflows. Your repo, your standups, your sprint cadence.

  • 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.
Our Process

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.
