Seeking a talented Drupal 7 System Admin (SysOps) that has extensive expertise with Couchbase, Memcache, Varnish and Nginx. We are an innovative, fast-paced early-stage company based in California. While this project is defined below, there may be an opportunity for on-going contract work once this project is successfully completed. **Before engaging your services, you will be interviewed by a domain expert. Do not submit a proposal unless you have extensive experience with Couchbase.** REQUIREMENTS Expertise with all of the following are required: * Drupal 7 sysops * Couchbase * Memcache & Drupal Caching * Nginx * Varnish * Cloudflare * Investigating and fixing issues with complex server and site configurations CURRENT SYSTEM CONFIGURATION * Drupal 7 e-commerce site with cloud-based horizontal scaling ** multiple nodes for frontend ** multiple nodes for MariaDB * memcached service * php library (PECL) for memcached * memcache module by drupal * nginx (no apache and no apache server libs) * Cloudflare * New Relic * Theming for site utilizes Drupal Panels * Dev, Staging and Prod environments * current configuration is similar to this setup (except we do not use apache or apache server libs for it): SOLUTION NEEDED We have encountered issues implementing Couchbase and are seeking a Couchbase expert to fix and optimize the implementation. * What seemed like a transparent subsitution (internal Couchbase memcache server in the place of standard memcache server) turned out to be a non working solution. * Couchbase has a service that acts like a proxy and runs on standard memcache port 11211, redirecting all memcache requests to it's internal memcache instances and it seems like drupal cannot communicate with this server. * Even though there is no error in status page, or error logs that memcache server cannot be reached, memcache statiscis page shows blank information (strangely showing the version of standard memcache server, even though it's off) PROJECT MILESTONES & PAYMENTS Milestone 1: Implement, configure and optimize Couchbase internal memcache service. * Instead of standalone memcache service (which we are currently using), implement, configure and optimize Couchbase internal memcache service. * Payment upon successful completion = 25% Milestone 2: Implement, configure and optimize Varnish * Payment upon successful completion = 25% Milestone 3: Assess nginx, Drupal 7, Couchbase and Varnish along with New Relic statistics to further optimize configuration and performance. * Compare current page load times to previous stats to demonstrate that site performance for each page load is significantly faster than it was previously. * If a page is found to have no performance gain or only minimal performance gain (less than or equal to 5% improvement) then investigate and resolve performance issues. * Payment upon successful completion = 50% Freelancer will report to our lead developer. Please be willing to work with our lead architect/developer to complete each milestone. This includes providing daily updates via HipChat and Skype voice. Successful completion means that milestone fully resolved and the items for that milestone, including both source and compiled code, have been fully deployed to, tested on and confirmed working on all three environments (dev, staging and prod servers/websites). Company determines when a milestone has been successfully completed. If all goes well on this project then there is potential for on-going contractor work.

I need a developer to advise in the structure and design of a database. I will be using Firebase and would need sound advice on how to design the structure. More details can surely be given but it would include users as well as various types of collections. No coding is really required but a good backend design mind and someone who can come up with a database structure that is performant and scales well is preferred!

My application is going to be very large, however like anything it has to start small. I am starting here. The program is called Nirvana, it is a stock screening and trading platform. There is no code written for it yet and were going to start from scratch. Currently I have lose documentation and am working on putting it together for a working application. I have however settled on a stack for the application, upgrades and recommendations are welcome however I have chosen these items due to their functionality and forward thinking. Node, RethinkDB, React, Express, Socket. If you are not familiar with Rethink please be upfront and do a little research you may like it! The DB will push data to the front end if it is updated so you dont have to continuously poll the database. Also it can perform joins and has a robust query language. The first iteration of the website will feature a homepage that has a lot of information on it, some charts, graphs, table data and a few news sections. Second page is the screening page, the user will be able to screen from a variety of pre-defined screens which we will code probably in rethink if I understand how it works. Third page will show the individual stock that the user selects. For this there are a few charting libraries available, I have seen and React Stockcharts. With either one I would like to do a lot of customization's in the future so please recommend which one is easier to work with or if you have another idea. In the backend there are some choices to make, I am new to Document Databases which is what Rethink is, so I am a little unsure about how to format the tables and documents, (rethink calls collections tables) seeing as were going to have to sort through a lot of data I dont know if we should have each stock its own table, or have dates as tables and stocks as documents? Im not sure. Also we need to get data into the DB. I have a service that can get the data into the DB however for now I just upload CSV files. In the future we would need to hook into an API to get the data into Rethink, then the real fun begins! ​ Full Stack Development, you'll be doing most of it. I have decided that instead of figuring out all this myself I would focus on RethinkDB and working in it, putting data where it belongs, making changes as needed and project management. You will be doing the rest basically. You should also be prepared to help me where I need it in my capacity as stated above. I may need help knowing where things are and how to put rethink code into the files. You will need to document you code, comment it very well and think of this as a very large application that can be worked on and updated/added onto easily. ​ In order to be successful you need to really be able to communicate with me, ask questions when you do not understand. Be able to see the big picture and communicate the vision and see it. If you cannot explain it to me then you dont understand it. In the end we'll have a few very well laid out functional pages!
