We are looking for someone to audit and troubleshoot existing python applications. There are two main applications that need to be retooled to include updates and new features. The first is a data collection and aggregation application, the application collects data from external platforms API's and stores it in mongo. The second is the application that queries the collected data and returns results via spreadsheet to users. Both user gunicorn, flask, celery, and other open source python components. This could work out to be a long term arrangement, depending on the results and quality of work performed. Please reach out if you're a python master and this sounds like something that's in your wheelhouse.

According to Google PageSpeed Insights: "In our test, your server responded in 2.6 seconds. There are many factors that can slow down your server response time. Please read our recommendations to learn how you can monitor and measure where your server is spending the most time." Similar results have been verified by checking the time-to-first-byte (TTFB) via (for example) http://www.bytecheck.com/ We would like to reduce the server response time to under 200ms (as per Google's guidelines in https://developers.google.com/speed/docs/insights/Server) Doing so will likely require strong knowledge and experience specifically with: - Open source PHP E-Commerce shopping cart, PrestaShop (http://prestashop.com/) - Why PrestaShop is typically slow (Modules) - How to safely unhook modules and increase the response time of Prestashop - Caching - Apache/Linux/MySQL - Putting Prestashop into 'debug' mode to troubleshoot load speed and see what SQL queries are being made and which 'hooks' are being loaded (and how long each takes) - Putting MySQL into debug mode to see how many SQL queries are being made Prior experience with Google PageSpeed Insights and mod_pagespeed is also preferred. You will be provided SSH access to the server currently running on Amazon EC2 with the ability to "sudo" as 'root'. All changes made should be documented, and ideally, we'd like you to take screenshots and document the exact process you followed (including steps to reproduce) as you go. Future work may be on offer for the successful candidate who is able to successfully complete this task to a high level of quality, as measured by (A) the newly reduced server response time, (B) elegance/simplicity of the solution and (C) not breaking anything else (including existing Google PageSpeed optimisations) on the server in the process.
