Oh Tien Cheng
I study computer science at NUS and build software around machine learning: search engines, LLM applications, and the backends and infrastructure that run them in production.
I've co-founded two small companies, built an LLM exam-marking platform during national service, and shipped MLOps tooling at DSTA. Right now I'm a backend intern at TikTok, president of RC4Entre, and on the NUS Hackers coreteam.
