C# / .NET Backend Developer
About Me
I am a C# / .NET Backend Engineer with over 4 years of experience building SaaS, B2B, and game backend systems. I specialize in microservice architectures and server-side business logic, with a strong background in distributed systems and event-driven architectures. Throughout my career, I have successfully improved system performance by up to 25% and reduced production bugs and delivery errors by 20 to 30%. I am passionate about designing scalable and secure backend services, particularly for Unity-based games and enterprise platforms.
Currently, I work at Valletta Software Development LTD in Tbilisi, Georgia, where I design and develop backend services for Unity-based games using microservice architecture. My responsibilities include implementing server-side game mechanics, building REST and gRPC APIs, and ensuring security through server-side validation. I also participate in backend architecture design to support high request throughput and future growth.
Previously, I contributed to a CRM platform for automating recruitment and HR processes for a European B2B client. I developed candidate management modules, designed REST APIs, integrated notification systems, and optimized database queries. I also wrote unit and integration tests to maintain code quality and reliability.
Before that, I worked on a task management and monitoring system for IoT smart container devices in Guangzhou, China. I designed backend microservices, built APIs, integrated asynchronous messaging, and optimized reporting queries. My efforts increased monitoring performance and reduced production bugs significantly.
I am currently pursuing a Master of Science in Software Engineering and hold a Bachelor of Science in Agronomy. I am fluent in Russian and English, with intermediate proficiency in Chinese. I am open to remote-only opportunities and prefer to avoid industries such as banking, crypto, military, alcohol, or tobacco. Outside of work, I contribute to open-source projects and enjoy game development, audio engineering, gaming, and table tennis.

Experience
Designed and developed backend services for a Unity-based game using microservice architecture focusing on scalability, reliability, and security. Implemented microservice-based backend services using C# and .NET. Developed server-side logic for game mechanics including matches, player progression, PvE/PvP flows, in-game events, and 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.
Worked on a CRM platform automating recruitment and HR processes for a European B2B client. Developed candidate management module with CRUD operations, filtering, and role-based access control using C# and ASP.NET Core. Participated in migration from .NET 6 to .NET 8. Designed and implemented REST APIs for admin panel and notification microservice. Integrated SMTP and Telegram notifications via RabbitMQ using MassTransit with retry policies via Polly. Optimized PostgreSQL queries using Entity Framework Core for analytics and reporting. Wrote unit and integration tests achieving ~60% coverage. Improved analytics report performance by 25%, reduced notification delivery errors by 20%, and increased delivery speed by 35%.
Developed task management and monitoring system for IoT smart container device. Worked in a 3-person Scrum team. Designed and implemented two backend microservices using C# and .NET 6. Built REST and gRPC APIs for task management and real-time monitoring. Integrated RabbitMQ via MassTransit for asynchronous processing of MQTT sensor data. Optimized PostgreSQL queries using Entity Framework Core for reporting. Increased monitoring performance by 25% through asynchronous processing. Reduced production bugs by 30% by improving test coverage and stability.
