I am Giancarlos Sandoval, a Software Architect & Mobile Tech Lead from Piura, Peru, focused on building scalable mobile and full stack solutions for banking, fintech, tourism, healthcare, transportation and enterprise platforms.
I specialize in Flutter, React Native, Clean Architecture, microapps, modular systems, real-time mobile services, Firebase, Node.js, CI/CD and reusable developer tools.
I enjoy transforming complex product requirements into maintainable architectures, reusable packages and production-ready mobile experiences.
Software Architecture ──► scalable foundations

I believe strong mobile architecture is not about adding complexity.
It is about creating clear boundaries, reusable components and predictable delivery.

I build packages and libraries that help mobile teams move faster with better architecture and reusable components.
| Package | Focus |
|---|---|
screaming_architecture |
Feature-first architecture generator based on modular/domain organization |
modal_date_picker |
Advanced cross-platform date picker for Flutter |
share_image_whatsapp |
Plugin for sharing text, images and QR codes to WhatsApp |
flutter_animated_bubble_background |
Reusable animated background component for Flutter UIs |
| Library | Focus |
|---|---|
react-native-custom-keyboard-pro |
Customizable keyboard with layouts, animations and mobile UX focus |
react-native-sliver |
Advanced scroll composition inspired by Flutter Slivers for React Native |
I design scalable foundations for mobile apps that need to grow beyond the first MVP: routing, data layers, error handling, state management, feature modules, API contracts and release workflows.
I create packages, libraries, UI components, design systems and internal APIs that reduce duplication and improve consistency across teams.
I build mobile solutions with realtime synchronization, geolocation, notifications, background services and cloud integrations using Firebase, Firestore, Google Maps and Node.js.
I care about maintainability, tests, code review, CI/CD, technical documentation and clean boundaries between presentation, domain and data layers.
These are the kinds of projects I am building and improving around my engineering focus:
| Project idea | Why it matters |
|---|---|
flutter_enterprise_architecture |
Production-ready Flutter starter with Clean Architecture, testing and CI/CD |
react-native-enterprise-starter |
Enterprise React Native foundation with TypeScript, API contracts and reusable components |
mobile_microapps_architecture |
Reference architecture for large-scale mobile apps using independent modules |
mobile_api_contract_validator |
CLI tool to detect breaking changes between backend APIs and mobile clients |
flutter_firebase_mobility_kit |
Realtime mobility starter with Firebase, Maps, tracking and background services |
flutter_banking_architecture_kit |
Banking-ready Flutter architecture kit with secure flows, modular features and enterprise delivery patterns |
