I specialize in pure backend development and have a wealth of experience in working with APIs to create robust and scalable server-side solutions. With a deep understanding of backend technologies, particularly in JavaScript and .NET, I excel at designing and implementing efficient and secure server architectures. In JavaScript, I am highly proficient in frameworks like Node.js and Express.js, allowing me to build powerful backend systems that seamlessly handle data processing, logic implementation, and integration with external services through APIs. In the .NET ecosystem, I leverage frameworks such as ASP.NET and .NET Core to develop high-performance backend applications. I have extensive experience in designing and developing RESTful APIs, ensuring seamless communication between different components of a web application or enabling integration with third-party services. With a meticulous approach to coding, a focus on performance optimization, and a thorough understanding of API design principles, I am well-equipped to meet the pure backend development needs of employers and deliver efficient, secure, and scalable solutions.
