I’m a software engineer focused on building reliable, scalable backend systems with strong experience in C# and .NET development. I design and develop product features with clean architecture and best engineering practices, prioritizing system reliability and measurable performance gains.

In my recent role, I diagnose and resolve complex backend issues across services and APIs, then optimize API performance using query tuning, caching strategies, and efficient data access patterns. I collaborate with product managers and QA engineers to translate business requirements into technical solutions, and I support frontend integrations and bug fixes when needed.

I also bring hands-on experience in AI response evaluation and data work. I review and compare AI-generated responses for accuracy and relevance, select the most appropriate output by context, and perform basic data annotation and labeling tasks to improve response quality.

Across projects and freelance work, I’ve built microservices-based architectures with API gateways (Ocelot), asynchronous workflows (RabbitMQ), and containerized deployments (Docker). I implement secure authentication and authorization, use clean architecture and domain-driven design principles, and continuously maintain documentation and performance-focused improvements to support maintainable systems.
