Project Overview

Jolly Match 3 is a commercial mobile puzzle game with 100k+ downloads on iOS and Android developed at Avantaj Prim S.R.L. As Senior / Lead Unity Developer within a team of 12 specialists (including 4 developers), I led client architecture, gameplay feature delivery, monetization systems, and A/B testing infrastructure. Beyond core puzzle mechanics, the project required robust client-server communication, resilient telemetry pipelines, and third-party SDK integrations maintaining stability across thousands of mobile device profiles.

Backend Integration & Server Communication

A commercial game is a connected product. In Jolly Match 3, the client communicates with backend microservices via REST API endpoints and Firebase services:

  • JWT Authentication: Secure user token retrieval and authorization validation before executing service requests.
  • Teams & Social Chat: Polymorphic JSON message deserialization supporting real-time chat, join requests, and life help requests across team members.
  • Client-Side Validation: String length, null payload, and rate-limiting safeguards to prevent invalid requests from touching backend endpoints.

Core Module Extraction & 3D Pipeline Migration

  • Reusable Core Git Submodule: Extracted the Match-3 core game logic into a standalone Git submodule decoupled from presentation assets, allowing other company projects to connect the core module and customize visuals independently.
  • 2D-to-3D Gameplay Conversion: Migrated the core 2D gameplay pipeline to 3D and optimized rendering, draw calls, and memory usage to maintain smooth mobile performance.

Analytics Infrastructure & Data Telemetry

Data-driven decision making required an extensive analytics foundation:

  • Custom Telemetry Manager: Custom analytics pipeline with structured logging handling dynamic difficulty adjustments, tutorial checkpoints, and monetization events.
  • Offline Resilience: Telemetry events generated during network dropouts are captured in a structured cache and flushed once network connection is re-established.
