Platform Engineer @ HASH.ai

Dec 2020 - May 2021

What I’ve worked on: Helped build the first iteration of their product, an ultra-performant web application (code editor) that allowed users to write Machine Learning algorithms which were then ran directly on the browser using WebAssembly for maximum performance.
Mind-blowing fact: The editor also allowed users to load their datasets (sometimes in excess of 1gB) to train the model. Quite a challenge considering how easy it is to lock the browser.
Performance: Employed cutting-edge React/JavaScript techniques for a smooth, high-performance user experience.
