Aspiring Data Scientist | Year 3 Data Science Student at Ngee Ann Polytechnic | Minor in Japanese Language
I am a Year 3 Data Science student at Ngee Ann Polytechnic under the School of InfoComm Technology, with a background in Computing from the School of Science and Technology. I work mainly with Python and spreadsheets, and have built skills in Machine Learning, Deep Learning, Data Wrangling and Generative AI solutioning and techniques. I’m interested in applying these skills to real‑world projects in data, AI and analytics.
A few projects that show how I apply data, ML and AI to real problems.
EngagePro RAG Chatbot
A Streamlit-based chatbot that uses Retrieval-Augmented Generation to answer user questions from a custom knowledge base, combining vector search with carefully designed prompts to produce accurate, conversational responses.
Tech: Python, Streamlit, LLMs, retrieval/RAG, prompt engineering.
Generative AI Image Creation (DCGAN & Stable Diffusion)
A generative AI project where I implemented and trained a conditional DCGAN for ASL image generation and also experimented with Stable Diffusion / SDXL via Hugging Face Diffusers to generate images from text prompts. Focused on training stability, prompt design and evaluating generated results.
Tech: Python, PyTorch, DCGAN, Stable Diffusion, Hugging Face Diffusers.
HR Copilot Studio Chatbots (Forvis Mazars)
A set of Microsoft Copilot Studio agents for HR, including an urgency triage assistant, a personal employee data bot with strict identity checks, and a policy/culture Q&A bot.
Tech: Copilot Studio, LLMs, prompt design, responsible AI concepts.
SawitPRO Data Discovery & Visualisation Dashboard
A data discovery and visualisation project for Agritech startup SawitPRO. I cleaned messy datasets and built dashboards to support market expansion decisions.
Tech: Data wrangling, dashboard/BI tools, exploratory data analysis.
