HTML5 canvas developer for trading charts

We are building our own trading charts (like tradingview) and are looking for someone to expand the team. Preferably someone who understands trading too. This is a long-term project which is why we prefer to pay per hour. The previous developer has left after 18 months.

Skills required:

HTML5 Canvas
JavaScript
Math (geometry)
Ability to draw canvas real-time geometrical shapes
Nodejs
AJAX
Canvasjs
