My services include designing and implementing RESTful and GraphQL APIs, optimizing database queries and application performance, integrating third-party services, and setting up cloud infrastructure on AWS or Azure. With extensive experience in frameworks like Nest.js and libraries such as Apollo, I can develop efficient microservices architectures, implement secure authentication and authorization systems, and create background processing solutions using technologies like RabbitMQ.
