About

Sophie is a production-ready, high-load dating application infrastructure built from scratch to deliver a modern, lightning-fast experience without legacy code.

​Core Architecture & Tech Stack:

• ​Backend: Developed in Go (Golang) using gRPC and Protobuf for ultra-fast, real-time bidirectional communication and low operational overhead.
• ​Database & Infrastructure: Powered by PostgreSQL and Redis, fully containerized with Docker, ensuring high scalability under heavy concurrent traffic for an exceptionally low hosting cost (€6.56/month).
• ​Web Admin Panel: A comprehensive dashboard built with Laravel, Inertia.js, and React. It features full user management, platform metrics, and Over-The-Air (OTA) theming to instantly change app styles without code redeployment.
• ​Mobile Client: 100% native Android application built with Kotlin, Jetpack Compose (Material 3), MVI/MVVM (StateFlow), and Hilt dependency injection.

​Monetization & Assets:

• ​Monetization: Pre-configured with a hybrid model featuring Google Play Billing Library v9.1.0 (VIP subscription tiers ranging from Daily $0.99 to Annual $79.99) and Google AdMob.
• ​Assets Included: Full source code across all repositories (Go backend, Kotlin Android client, Laravel/React admin panel), Figma UI/UX designs (Dark & Light modes), and an officially approved Google Play app (version 1.0.2).

​Designed as a flexible platform, it serves as an ideal turn-key solution for entrepreneurs, agencies, or media buyers looking to launch into micro-niches or deploy white-label dating solutions instantly.
