Hi, I'm Gilbert. I Build AI for People.

Building Tomorrow’s AI Today

I'm a Data Science student at UC Berkeley with a focus on building the next generation of AI. My skill set spans data science, machine learning, deep learning, computer vision, NLP, LLMs, RAG, knowledge graphs, and more.

I’ve completed 10 internships (IBM Research, SK Hynix, etc.) with over a year of research at the Stanford AI Development & Evaluation Lab and the UC Berkeley School of Information. I am proud to have won first place at CalHacks 11.0, the world's largest collegiate hackathon, and to have served as the president of our coding club, all while earning a scholarship.

I thrive on tackling new challenges and continuously seek opportunities to grow and make a meaningful impact. Completing over 40+ online courses and earning 3 professional certifications keeps me at the forefront of this constantly evolving field.

I break down complex AI/ML concepts on LinkedIn so they’re accessible to newcomers and those from diverse technical backgrounds in a fun and engaging way, where I’ve been recognized as a 3x Machine Learning Top Voice. Outside of work, I enjoy hiking, the gym, and studying with music.
