AI Agents Working Together

Our development process uses specialized AI agents, each with a specific role. They collaborate seamlessly to build your application faster and smarter.

Development Workflow

Multiple Developer Agents work simultaneously on backend, frontend, iOS, and Android.

04
Deploy

Test & Deploy

QA Agent ensures quality while DevOps Agent deploys to AWS with CI/CD pipelines.

Development Workflow

From Feature to Production

Every feature follows our proven workflow: Development → Acceptance → Your Approval → Production. You stay informed at every step and have full control over what goes live.

Development Workflow Pipeline
Stage 1

Development

AI agents build your feature collaboratively. Backend, frontend, and mobile teams work in parallel. You receive real-time updates on the project board.

  • Code written and reviewed by agents
  • Automated tests created
  • Progress visible on your dashboard
Stage 2

Acceptance Environment

Features are deployed to your private acceptance environment. Test the feature yourself, see exactly how it works before it goes live.

  • Live preview of your feature
  • Test on real devices
  • Share with stakeholders
Stage 3

Your Approval

You decide when features go live. Approve with one click, or request changes. Nothing reaches production without your explicit approval.

  • One-click approval process
  • Request changes if needed
  • Full control over releases
Stage 4

Production Deployment

Upon approval, we deploy to production. Web apps go live instantly. Mobile apps are submitted to App Store & Play Store with managed release timing.

  • AWS production deployment
  • App Store submission (1-3 days review)
  • Play Store submission (few hours - 3 days)
iOS

App Store Release

Apple reviews each update. We handle the entire submission process including screenshots, descriptions, and compliance.

Review: 1-3 days Expedited available
Android

Play Store Release

Google's review process is typically faster. We manage staged rollouts and monitor for any issues.

Review: Hours - 3 days Staged rollout
