Technical Case Studies

1️⃣ Multiplayer & Real-Time Systems in Unreal Engine

Projects: Whoosh, 3D Jet Fighting

Context:
Developed multiplayer gameplay systems for real-time action games, starting from low-level DirectX/DirectPlay foundations to modern Unreal Engine replication systems.

Challenges:

• Player state desynchronization in multiplayer sessions
• Late-joining players missing game state
• Performance constraints for real-time simulations

Solutions:

• Implemented server-authoritative architecture for player and game state
• Used Unreal Engine’s replication features and OnRep callbacks for reliable syncing
• Optimized tick rates and network replication to balance performance and accuracy

Impact:

• Zero desync issues in production
• Scalable multiplayer system supporting 8–16 players in real-time matches

2️⃣ Engine-Level SDK Development

Project: mod.io

Context:
Built Unreal Engine SDK/library for external developers to integrate mod.io platform into their games.

Challenges:

• Must be robust and easy for other studios to use
• Support multiple platforms (Windows, Mac, consoles)
• Provide clear API and developer-friendly tooling

Solutions:

• Designed modular and extensible SDK architecture
• Added comprehensive documentation and sample code
• Built production-level integration tests

Impact:

• Used by multiple studios successfully
• Reduced integration time and errors for developers

3️⃣ Blockchain Integration in Games

Projects: PlayTradeX, Shiba Inu

Context:
Integrated blockchain features into real-time game clients, including wallets, token transactions, and NFT-based systems.

Challenges:

• Secure client–server wallet interactions
• Low-latency blockchain calls for real-time gameplay
• Cross-engine support (Unity + Unreal)

Solutions:

• Implemented secure AES/RSA client-side encryption for sensitive data
• Designed asynchronous blockchain APIs to avoid gameplay lag
• Created reusable integration framework for multiple projects

Impact:

• Live in production games with secure in-game token transactions
• Supports multiple game engines and platfo
