Valletta Software Development LTD

May 2024 – Present
Tbilisi, Georgia www.vallettasoftware.com
Game Backend (Unity Project)

Designed and developed backend services for a Unity-based game using a microservice architecture with a strong focus on scalability, reliability, and protection against invalid client actions.

Responsibilities:

  • Designed and implemented microservice-based backend services using C# and .NET
  • Developed server-side logic for game mechanics: matches, player progression, PvE/PvP flows, in-game events, notifications
  • Built REST and gRPC APIs for communication between Unity clients and backend services
  • Implemented asynchronous event processing using RabbitMQ and MassTransit
  • Added server-side validation to prevent cheating and client–server desynchronization
  • Participated in backend architecture design for high request throughput and future user growth
