Hi SMU, Hello World!

I landed at Singapore Management University as a Computer Science undergraduate, blessed with the Tahir Indonesian Scholarship! C became my first programming language. It was painful, but I persevere through it (barely). I dove into programming fundamentals, statistics, databases, and got my first taste of UI/UX design.

First AI Encounter...

DSTA Brainhack 2023 threw me headfirst into Computer Vision and NLP. My friends and I were totally clueless, but something clicked! This magical world of machine learning made me want to major in AI, and I never looked back.

Full-Stack Development

Git, backend, frontend, everything! Finally learned the art of full-stack development and shipped my first real mobile app :). I deepened my understanding about network protocols, data structures, and algorithms as well. Some pictures from my favorite classes!

LLM Engineering Debut

First internship unlocked! We shipped a GenAI chatbot solution and I dove deep into LLM engineering. I learnt the art of retrieval, prompting, and evaluation to keep those AI answers helpful and grounded in reality.

AI, AI, and AI Everywhere

Plot twistβ€”the company called me back for more adventures! Tackled Fraud Detection, built internal Operations dashboards (full-stack style), and worked on Time Series Forecasting. I've explored everything from image-to-image translation to reinforcement learning, while adding a second major in Business Analytics. The AI journey keeps getting wilder!
