Product Ecosystem
NAGOLOCY
End-to-end educational product ecosystem for mastering Ukrainian word stress for NMT 2026
FlutterDartGo
Project Overview
NAGOLOCY is not just a mobile app but a full-stack educational product built around one narrow but high-value problem: helping users master Ukrainian word stress for NMT through a polished, gamified, cross-platform experience. We took the product from concept, positioning, visual language, and interaction design through engineering, monetization, release preparation, store publishing, and ongoing operational tooling. Under the hood, the ecosystem combines a Flutter client, a Go service layer, a secure admin panel, and a dedicated marketing landing, giving the product a real acquisition, retention, support, analytics, and moderation loop rather than a disconnected MVP.
Product Surfaces
mobile app
iOS & Android App
The core Flutter product with offline-capable training, multiple learning modes, achievements, leaderboards, authentication, ads, and premium access.
admin panel
Admin Control Panel
A separate operations surface for analytics, audit logs, feedback moderation, user management, subscription overrides, notifications, and secure admin workflows.

The Challenge
Turn a narrow educational topic into a product that feels premium, memorable, and worth returning to every day rather than a one-off utility.
Deliver a coherent ecosystem where acquisition, onboarding, learning, monetization, support, moderation, and analytics connect cleanly across four separate codebases.
Keep the experience fast and scalable while supporting offline training, cloud sync, premium access, ads, security-sensitive admin flows, and public release on both Apple and Google storefronts.
The Execution
Built the mobile application in Flutter around modular feature slices for auth, dictionary, game modes, spaced repetition, missions, achievements, analytics, leaderboard, profile, and subscription management. The app uses Provider, GetIt, GoRouter, Drift/SQLite, Dio, Firebase, and a deferred bootstrap that keeps startup responsive while initializing sign-in, notifications, ads, and subscriptions.
Implemented the backend in Go with Gin, PostgreSQL, Redis, MinIO, Firebase Admin, automated migrations, event listeners, background workers, audit services, feedback pipelines, storage handling, Telegram notifications, and RevenueCat webhook processing for premium entitlement reconciliation.
Developed a dedicated Next.js admin panel with Firebase-authenticated access, staged security routing, 2FA flows, audit logs, user directory, analytics dashboards, feedback resolution, CSV exports, system telemetry, and manual subscription grants and revocations.
Created the public Next.js landing as a separate marketing surface with strong SEO structure, store routing, support and policy pages, data-deletion handling, backend-integrated feedback collection, and Firebase-based web analytics.
Carried the product through full-cycle delivery, including product framing, visual language, styles, interface direction, release preparation, store assets, publishing to Google Play and the App Store, and ongoing monetization through AdMob and premium subscriptions.
The Outcome
“A live, multi-surface educational product with public distribution on iOS, Android, and the web, supported by an internal operations layer instead of manual ad-hoc handling.”
“A maintainable architecture where mobile, backend, admin, and marketing can evolve independently while still sharing one consistent product model and operational loop.”
“A production-ready foundation for long-term growth: secure admin workflows, feedback intake, subscription controls, observability, release versioning, and a clean path for future content and feature expansion.”
