Relevant Experience

2023 -
Canva, Machine Learning Engineer
On the Visual AI Platform team.
2021 - 2023
EODC, Software Developer
Worked with (big) satellite imagery. Wrote & maintained a backend + REST API for on-demand Earth Observation data processing using Python. I also setup and nurtured the underlying Kubernetes cluster and practised CI/CD, GitOps, Devcontainers and Infrastructure-as-Code to stay sane.
2020 - 2021
Research Sabbatical
Took some self-funded time off to figure out what I want to do next. I ended up wildly studying lots of different things in math, history & philosophy that I didn't have time for before. Tech projects I worked on:
  • Built, a codebase visualisation tool
  • Created a habit-tracking Slack bot for myself
  • Worked through the fastai course
2018 - 2020
Echobox, Data Scientist
I was responsible for developing, testing, deploying and monitoring machine learning models for a wide variety of use-cases, e.g. scoring, classification and clustering tasks.
2016 - 2017
University College London, Research Assistant
