Q: Hi Yi Chen, tell us more about yourself!
A: I am Yi Chen, a first year college student majoring in Artificial Intelligence & Society at National University Singapore (NTU). This summer, I spent three months as an AI Engineer Intern at Resaro in Singapore. My journey was nothing short of rewarding — one that gave me a closer look at what it means to build and assure AI systems in practice.
Q: What inspired you to apply for an internship at Resaro?
A: I first heard about Resaro back in 2022 while interning at the Government Technology Agency (GovTech). Even then, Resaro’s mission on ‘enabling an AI market worthy of trust’ stood out.
Fast forward to 2025, AI systems are rapidly shaping industries, and the question of trust, safety, and accountability has never been more urgent. AI has begun its conquest in becoming the new world order and the prospect of tech jobs in the market faces a bleak future from this paradigm shift. I wanted to be part of work that looks beyond building AI for capability alone, and instead asks how it can be deployed responsibly and at scale — especially in high-stakes industries.
Q: What did you work on during your time at Resaro?
A: At Resaro, I joined the ‘Echo’ team, where I helped to develop the LLM platform that serves as a reliable and robust test suite for LLM use cases.
My work ranged from experimenting with powerful LLMs, to building custom Application Programming Interfaces (APIs) using AWS Services, and designing responsive UI (e.g., ReactJS) that enhances user experience. I also learned to navigate frameworks such as LangChain and HuggingFace that are becoming standard tools in the field.
On top of that, I was also given an opportunity to represent Resaro at a round table discussion conducted by IMDA on its LLM Starter Kit Tool for developers. Through this, I learned how to translate ideas across technical and non-technical stakeholders.
Q: What did a typical day look like for you at Resaro?
A: Life at a startup can be ‘intense’, but I really enjoyed my time here. The environment was collaborative, and as an intern I was encouraged to challenge ideas, propose solutions, and contribute meaningfully to discussions. From lunches with the Singapore team to virtual syncs with colleagues headquartered in Germany, the sense of connection was constant.
My favourite memories (and the highlight of my internship) are the small but deliberate moments of team bonding, whether during monthly outings or conversations over coffee that went beyond work.
