Kia Ora 👋

I am a Geospatial Data Scientist from Malaysia 🇲🇾 working remotely and thinking about where to go next! My background is in Geography, with a particular interest in Earth Observation using satellites 🛰️, having done cool research on Antarctic ice dynamics during my PhD in Aotearoa/New Zealand 🥝. Specifically, I work on applying Deep Learning methods to Remote Sensing datasets, keeping busy on the leading edge of data-driven research in the Earth Sciences.

These are some of the hats I wear:

• ☁️ Machine Learning Engineer in the GeoAI team at Development Seed
• 🌏 Core Developer of PyGMT: A Pythonic Interface to the Generic Mapping Tools

I'm currently:

• 🦀 Learning Rust, and trying to get into the GeoRust ecosystem
• ☯️ Developing a Python package called zen3geo for building Earth Observation and geospatial data pipelines
• 🔭 Making open source contributions to the Pytorch ecosystem and Pangeo community, all in the PyData world!

Want to connect?

• 💻 I'm open to building partnerships with folks working on open geospatial tools, specifically with a Remote Sensing focus, so reach out!
• 📫 Track me on Mastodon as @weiji14, or find some other links on my website
• 👀 Be sure to check out my cool Computer Vision projects:
  • DeepBedMap - Super Resolution Generative Adversarial Network to resolve the bed topography of Antarctica
  • DeepIceDrain - Finding subglacial lakes using unsupervised DBSCAN clustering
  • DeepSlide - Self-supervised learning on SAR data for change detection, for the FDL2022 NASA Earth Science challenge
  • Crevasse detection and navigation - Done using Image Segmentation + Reinforcement Learning
  • S2S2Net - Sentinel-2 Super-Resolution Segmentation Network using a Vision Transformer model (SegFormer)

⚡ Fun fact: I was brought up trilingual, and am fluent in English, 中文 & Bahasa Melayu.
