Chrystian

Master’s Student in Computer Science | Universität des Saarlandes (UdS)

Hello! I’m Chrystian, a graduate student at UdS, enrolled in the 2025 winter semester. Prior to this, I worked at Samsung Research ID, where I collaborated directly with the Cloud Infra R&D Group since 2022, focusing on day-to-day deployment operations, ensuring service reliability, and quickly resolving critical production issues. I maintained, but was not limited to, CI/CD pipelines, managed multi-cloud migrations, and handled Zero Downtime Deployments.

As an AI and Software Engineer, I also experimented with optimizing distributed query engines using a combination of caching solutions alongside machine learning and reinforcement learning techniques. I also have professional experience accelerating and fine-tuning large language models with LoRA and quantizing them for mobile use.

I graduated with a BSc in Computer Science from Gadjah Mada University, where I developed a GAN model for generating symmetric patterns with limited data. Since then, I’ve been passionate about integrating AI into real-world applications and continuously seek new challenges to advance this field.
