Hi, I'm KIMSENG DUONG
Full Stack Engineer & System Architect
With over 4 years of experience building scalable, secure, and high-performance systems. I specialize in system architecture, API development, and automation with expertise in cloud deployment, DevOps, and containerized applications.
I focus on developing full-stack solutions with an emphasis on business logic, data security, and AI-driven systems, while following agile methodologies and best practices for code quality.
About Me
I'm a Full Stack Engineer with substantial industry experience. I turn business needs into working software solutions. I combine big-picture planning with hands-on coding to build systems that work well today and can grow tomorrow. My focus is always on creating reliable, secure, and fast applications.
I'm skilled in building systems with separate services that work together (microservices), creating reliable connection points for different systems (APIs), and developing complete applications. Some of my best work includes: a point-of-sale system that significantly reduced business operating costs, an online store that handles high-volume sales daily, and tools that dramatically improved software update efficiency.
I speak three languages fluently - Khmer (my native language), English, and Chinese. This helps me work well with people from different backgrounds. I enjoy team-based work and use organized methods to create software that users love. I'm always looking for ways to improve how we build software and share what I learn with my team.
