Hi, I'm Bowen 👋

I'm a Machine Learning / AI Engineer based in Toronto, Canada, focused on taking models from research to production – especially in search, retrieval, and personalization systems. I care about clean infrastructure, observability, and building systems that are reliable and maintainable.

  • 🔭 Currently working on:

    • Two products that hopefully can be useful for a lot of people
    • Search and retrieval systems that surface the right content at the right time
    • Personalized recommendation systems (e.g., two-tower architectures) from training → deployment → monitoring
    • ML infrastructure for reliable model serving and evaluation
  • 🌱 Learning more about:

    • Kubernetes, scalable inference, and production observability
    • LLM applications for search, ranking, and summarization
    • How to turn side projects into real, revenue-generating products
  • 🎯 Longer-term direction:

    • Exploring what it takes to run a lean, one-person ML/search practice, from idea → prototype → paying users

💻 Tech Stack

Python TypeScript SQL

React FastAPI

PyTorch TensorFlow HuggingFace LangChain LlamaIndex

Docker Kubernetes GitHub Actions

PostgreSQL Redis

🔍 What I’m interested in

  • 🔎 Search and ranking: query understanding, retrieval, and learning-to-rank
  • 🎯 Personalization: embeddings, two-tower models, and user–item interaction modeling
  • 🧩 ML infra: deployment, orchestration, observability, and evaluation loops
  • 🤖 LLM-powered products: retrieval-augmented generation and agent-like workflows that plug into production systems

🤝 Freelance & collaboration

I’m open to:

  • 🧭 Helping teams improve or build search and personalization systems end to end
  • ⚙️ Turning existing ML prototypes into production services
  • 🌐 Collaborating on open-source tooling for ML deployment and monitoring

If you’re working on search, personalization, or ML infra, I’d love to chat.
