At Alphas.Technology, I architect resilient microservices with Java, Spring Boot, and Spring WebFlux for enterprise banking clients. I also implemented custom MCP servers and AI tool integrations to automate backend workflows.

I optimized high-volume application performance and database operations, reducing query latency by 30%. I designed event-driven systems using AWS serverless services and AWS IoT Core, and expanded backend capabilities with .NET 8 and Azure.

At navicu.com, I built REST APIs and backend services for hotel and travel management platforms, improving response times by 25% through SQL optimization and PostgreSQL indexing. Earlier, I worked as a freelance Software Developer and a product support analyst, where I prepared reports using MSSQL Server.
