Hey, I’m Nicholas Lee.
Data Scientist at PwC. MSc Statistics at NUS. Building tech tools for finance.
Data Scientist Associate at PwC Risk Services and MSc Statistics student at NUS. I like building end-to-end AI tools - the kind that actually get deployed and used, not just prototyped. This site has a chatbot you can quiz about me, plus a couple of projects I've shipped.

Chat with Me
An AI chatbot trained on my resume and a personal write-up. Ask about my background, experience, or projects.
Financial Statement Scanner
Upload company PDFs. Get back an Excel workbook with the four core financial statements extracted and normalised to a US-GAAP chart of accounts.
AI Due Diligence / Memo Generator
Upload a pitch deck or paste a company link for targeted due diligence, or describe your criteria for a company recommender. A multi-agent workflow researches each section in parallel and cites every source.
Side quests
Weekend builds with more wink than gravitas. New ones land here whenever I get restless.
CNY Zodiac Luck Predictor
LiveFortune tellers give wildly different luck readings for people of the same zodiac. Care to see what mine says about yours?
News Aggregator Bot
LiveA daily Telegram digest of tech and finance news. My colleagues and I use it to keep up without opening 12 tabs a morning.
Orion Baccarat Bot
LiveMy friends and I love gambling. When we over-order dinner, this bot decides who eats the leftovers.
Want to know me better?
Chat with the bot to get a feel for who I am, then reach out directly. I’m always up for a coffee chat about statistics, deployment, or the state of markets.
