React Native • Flutter • HybridNative & KMP Targets

Cross-Platform to Native & Kotlin Multiplatform

Break free from JavaScript bridge latency, brittle plugins, and dual maintenance overhead with structured, brownfield migration paths.

AI-Assisted Transpilation + Senior Architectural Review

Combining AI coding agents (Claude Code, spec-driven planning) with 11 years of senior mobile engineering to ship tested native migrations in weeks.

STAGE 01AST Mapping

AI-Assisted Transpilation

FOCUS:Codebase transformation & AST mapping

Key Deliverables: Rapid extraction of models, business logic, and UI components from legacy cross-platform code.

  • Automated AST parsing of React Native / Flutter components into Kotlin/Compose models
  • High-throughput extraction of TypeScript/Dart business logic without manual boilerplate
  • Algorithmic detection of deprecated plugins and native iOS/Android bridge dependencies

FLAGSHIP REFERENCE ARCHITECTURE

Proven on Zora Community and the Marketplace Core

These starter kits aren't toy counter apps. They derive from Zora Community (open-source KMP app for Android, iOS, and Desktop built in under 4 weeks with Clean Architecture, MVI, tests, and green CI) and the Zora marketplace architecture using Ktor WebSockets and SQLDelight persistence.
