Maintaining and building features in a HighCharts.js App

Project roles: Developer

Project deliverable: Ensuring proper and accurate functionality of a financial chart app

I subcontracted with a lead developer to administer an inherited, outsourced HighCharts.js app displaying years of stock market data.

The code, split across a dozen .js files, needed frequent debugging due to questionable architectural decisions (the administrator is given monthly data updates in the form of a multi-gigabyte CSV file).

I built a new feature into the app, allowing financial data to be sorted by business quarter in addition to years and months.

Site built with Gatsby. Definitely a fun tool, check it out:
