Javascript Performance Engineer

NOTE: PLEASE CAREFULLY READ THE JOB POST BEFORE BIDDING ON IT. FAILURE TO DO SO WILL RESULT IN YOUR PROPOSAL BEING IMMEDIATELY DISCARDING. ============================================================================== We have an application that displays a grid of millions of rows in javascript and are looking to optimize certain operations with it. The grid uses [login to view URL] and is built with several features on top of that. While you do not need to have prior experience with this grid, you should be excellent in profiling and optimizing javascript/c++ applications where measurements are taken in milliseconds. Ideally, we're looking for someone with a deep background in either C/C++ (perhaps 5+ years) and has experience with highly performant javascript applications. Think something like a financial application or ad-buying platform where response times needs to be around 5ms or so. Please do not bid on this project unless you have this specific requirement -- we are NOT looking for Front-end developers with React/Angular/Node experience, we're looking for someone closer to a performance engineer who is very good at the browser/javascript level. In your bid please address the following: 1. Sample javascript code of a non-trivial application where response times are critical (can be a repository or screenshot or zip or whatever). Explain what the necessary response times need to be. 2. Sample C or C++ code of a non-trivial application. Explain what the necessary response times need to be. 3. Do you have any experience with fin-hypergrid?
