👋 I’m Timothy and I live in sunny Singapore with my wife and three cats.
With over 8 years of experience building AI-driven products, I have strong proficiency in PyTorch and extensive expertise in fine-tuning Large Language Models and creating LoRAs for Diffusion models.
You can find me on GitHub, Hacker News and LinkedIn.
Skills
Experience
I lead a team that builds custom Machine Learning models for startups and established companies.
Recent projects include:
- LLM-powered Interview Tutor: mock coding interviews, featuring real-time voice and text interaction, built in Next.js using the OpenAI Realtime API. Deployed on Vercel and Pusher.
- AI-native Image Editor: consistent image generation in a visual interface built in Next.js. Deployed on Replicate and prototyped in ComfyUI using Stable Diffusion and ControlNet.
- Horse Race Betting Models: 18-month project modelling horse race probabilities for a Hong Kong betting syndicate. End-to-end pipelines built using custom PyTorch models and scikit-learn transformers.
- Handwritten Mathematical Expression Recogniser: built an online handwriting recognition system for mathematical expressions for a Hong Kong based startup, that generated LaTeX markup as output.
Product discovery website deployed on a cluster of AWS EC2 instances running web scrapers and custom Named Entity Recognisers. The system was used to identify and link 10,000+ products from news sources.
Note-taking application incubated through Entrepreneur First, a startup scheme for UK’s brightest graduates. Built the Ruby-on-Rails back-end, the jQuery bookmarklet and the PostgreSQL comment system.
