Acerca de Saray

I am a freelance software developer with over 5 years of experience specializing in C# and .NET technologies. I help businesses design, build, and optimize applications tailored to their needs, whether it’s creating new software from scratch, enhancing existing systems, or fixing critical issues. My services include back-end development with ASP.NET Core, database design with SQL Server/PostgreSQL, API integration, and performance optimization.

I work on a task-based, fixed-fee model, ensuring transparency and predictable results. Clients value my ability to deliver reliable, well-documented, and tested solutions on time. If you need a dedicated developer to bring your project to life or improve your current application, I would be happy to help.
