Hi, I’m Đoàn Ngọc Nguyễn, a mobile and backend developer based in Ho Chi Minh City, Vietnam. I have strong experience in mobile application development and growing expertise in backend engineering and AI systems. I enjoy designing end-to-end systems that combine frontend, backend, and AI capabilities to solve real-world business problems and collaborating with product and engineering teams to deliver user-friendly, scalable solutions using Flutter, Kotlin, Dart, REST APIs, and real-time communication technologies. Currently, I’m focusing on Golang backend development and LL(M)-powered chatbots and agent solutions. I’m passionate about building end-to-end systems that blend frontend, backend, and AI to address practical business challenges, optimizing performance, and enhancing user engagement through modular, maintainable architectures.…Hi, I’m Đoàn Ngọc Nguyễn, a mobile and backend developer based in Ho Chi Minh City, Vietnam.
