I build reliable backend systems, APIs, and application features with a focus on clean architecture, maintainability, and practical business requirements. I can help with:

REST API development

backend features and business logic

authentication and authorization

database integration

third-party API integrations

bug fixes and backend refactoring

testing and debugging

performance improvements

internal tools and automation

extending existing applications I work with Python, Node.js, Java, C#, ASP.NET Core, and other suitable backend technologies depending on the project. Whether you need a new API, a backend feature added to an existing product, or help fixing and improving an existing system, I focus on delivering code that is reliable, understandable, and easy to maintain.
