Hi, I'm Han. I'm a System Engineer and Full-Stack Developer passionate about building robust systems & scalable applications. My focus is machine learning, artificial intelligence, distributed systems, cloud infrastructure, and modern web development.
About me
I am a junior software engineer who loves to learn new things and explore many things around the world. I have learned several programming languages including Python, Java, JavaScript, C#, Go, and Rust. Currently, I am working as a System Engineer maintaining server infrastructure, which gives me hands-on experience with real-world systems and operations.
During my college journey, I explored various fascinating topics in computer science. In the AI field, I learned about information retrieval, machine learning, data mining, image processing, and natural language processing. I also dove deep into infrastructure, studying distributed systems, computer networks, cloud computing, and advanced databases. This diverse knowledge helps me understand both the theoretical foundations and practical implementations of modern software systems.
What drives me is the excitement of continuous learning and the challenge of solving complex problems. I'm always eager to explore new technologies, experiment with different approaches, and understand how things work under the hood. Whether it's building applications, optimizing infrastructure, or diving into AI/ML projects, I enjoy every step of the learning journey and look forward to growing as an engineer.
