This was the first major project I worked on at Micasense, and it was porting the entire frontend app to React. I was the sole frontend engineer on the team.
I did work with a few contractors to help with the project -- React was new and the folks at Formidable (I believe they are under a different name now, maybe Nearform) were helpful getting us up to speed on best practices.
Micasense ended up dropping software development to focus on their hardware devices so most software development roles were eliminated and I ended up moving on to work at Igneous (and then Amazon) shortly afterwards.
Still, I consider this project a success, as we greatly improved the tech stack and extensibility of the app by moving to a more declarative pattern with React.
I don't think this app is still alive anywhere today, but the gist of it was that it was a web app that allowed users to view multispectral drone imagery in a map interface after uploading their data and having our systems process it.
There were some interesting UI challenges -- including displaying a timeline of data, a color histogram, and dealing with syncing React state and Leaflet.
I even ended up shipping a bug fix to Leaflet Draw.
