Frontend — Engineering11 Full-Stack Foundation

The Foundation provides comprehensive frontend support across multiple frameworks and platforms, enabling teams to build modern, responsive applications with consistent patterns and integrated platform services.

Overview

The Foundation’s frontend ecosystem provides:

• Seed Applications for Flutter, Angular, React, and React Native
• Shared Component Libraries for consistent UI/UX across each platform
• Authentication & Authorization patterns integrated with the Foundation backend
• White-Label Theming systems for multi-tenant customization
• Build & Deployment tooling for CI/CD across web and mobile

Platforms

Flutter

• Composable SDK platform (25+ packages) managed by Melos
• Abstract DI, typed SDK initialization, module facade pattern
• 140+ widget E11 UI library with white-label tenant theming
• GitHub Actions CI/CD to TestFlight and Google Play

Shared Principles

Across all platforms, the Foundation emphasizes:

• Feature-based module structure — code is organized by domain feature, not by file type
• Backend integration — each platform has typed SDK packages or clients for Foundation backend services
• White-label theming — theming systems support per-tenant customization from server configuration
• Error handling — structured error types and centralized error monitoring (Rollbar)
• Layered architecture — shared Foundation packages → optional product SDKs → product applications

What You Build

While the Foundation provides the infrastructure, your team builds:

• Product-specific UI and user workflows
• Custom components for your domain
• Business logic in the frontend
• Integration with your custom backend services
• Branding and visual identity
