FlutterFlow Development, Accelerated with AI

Prototype to Production

Claude Code speeds up the custom Dart code, custom functions and API work that take a FlutterFlow prototype to a production release.

The whole Unico Connect team uses Claude Code daily. Engineers are expected to understand what AI produces, and a tech lead or senior developer reviews the work before it ships.

What Our FlutterFlow Developers Build

Cross-Platform Mobile Apps

iOS and Android apps from a single FlutterFlow project. Native performance with platform-specific navigation patterns and device APIs.

Web + Mobile from One Codebase

Progressive web apps and mobile apps sharing the same business logic and UI components. Deploy to web, iOS, and Android simultaneously.

Custom Code Integration

Extend FlutterFlow with custom Dart code for advanced features: complex animations, native device access, custom widgets, and third-party SDK integration.

Firebase & Xano Backends

Full backend integration with real time databases, cloud functions, authentication, and file storage through the native Firebase and Supabase integrations, or Xano connected through FlutterFlow API Calls.

MVP & Prototype Development

Rapid mobile app prototypes for investor demos, user testing, and market validation. Functional apps delivered in weeks, not months.

FlutterFlow to Flutter Migration

Export and enhance FlutterFlow projects as pure Flutter code for teams that want to transition to a fully coded development workflow.

VETTING PIPELINE

How engineers earn a spot on our team

Our hiring process has three stages, from the application screen to a project deep dive with background verification, and every new engineer then serves a probation period.

4 checks
Application screen

We source engineers across India through LinkedIn, Wellfound, employee referrals and outbound headhunting. Every application is checked for stack relevance, years of experience, English and time zone overlap before it moves to a technical interview.

60 to 90 min
Live coding and scenario questions

A live coding round of 60 to 90 minutes in the primary technology of the candidate, followed by scenario based questions on practical applications of that technology.

3 checks
Project deep dive and background verification

Candidates walk us through a recent production project, covering the architecture decisions and what they would change in hindsight. A third party background verification agency then confirms prior employment, education and identity.

Probation
A probation period follows

New engineers then serve a probation period, and those who do not meet our bar do not continue with us.
