We have a Ubuntu 14.04 server, running a standard WordPress + nginx + php5-fpm + mysql stack. Our traffic this weekend is higher than normal and even with increasing server memory and cpu power, we are still experiencing extremely high load which is affecting user experience. We use w3 total cache to cache pages, with separate mobile and tablet themes so all users get cached pages. Even with nginx set up to send cached HTML pages, numerous PHP workers are running. The cached pages are being served, but load still remains high. We need someone to examine the configuration and see if anything can be done. The cached pages work much better than actually logging in and making changes via the admin panel. Hopefully things can be optimized this weekend and fine tuned in future.

Have you read this article in Wired http://www.wired.com/2015/04/united-healthcare-telemedicine/ ? I would like to create a WebRTC based telemedicine platform MVP for a specific subset of medical professionals. The basic description is: End to end integration and someone who can set up a database structure with scheduling blocks, build a forms interface that can take in dates and times and carry stuff across multiple steps, read and write to the database, handle in-line user registration, integrate with a background scheduler to send automatic emails, sending and receiving background requests to a payment gateway, all within a system they may not yet be comfortable with (comfortable with may mean having 9 months experience in). They'll need to know SQL, CSS, HTML, PHP, Linux administration, JavaScript, system architecting, HTTP, payment gateways, and some other technologies, and a whole range of soft skills (e.g. user experience design, communication skills, writing skills).

I have Odoo installed on my Ubuntu 15.04 server. I need aeroo reporting engine installed and get it working. For an experienced developer, it should be a quick job. I tried it myself but couldn't get it working to print pdf reports in odoo using aeroo odt templates. If you can make it work, we may have future jobs for you.

I have a web server that is very unstable, keeps crashing with database probs and having security issues. It works on zpanel and is deployed on digitalocean servers. Knowledge of mail admin would be an asset. I can provide more details later.

I currently have a Synology file server set up without a domain. We have 10 computers. I would like my users setup and managed on a Windows Server machine. I have Windows Server 2012 on a computer you can teamviewer into, or we can try VMWare. Further, I'd like my router and server configured for VPN.

I have a centos server that i have installed FreePBX. I have an issue with freepbx sending emails and i think this is soley a postfix and cert issue. it will not send the voicemails from the server and i do not know how to resolve. i installed a sysadmin package from freepbx but that did not fix it.... i see the debug and i know the errors are isolated to this i believe.

I have a synology ds1512+ /w DSM 5.2. After a software upgrade once upon a time, our speeds of grabbing files from the server and uploading them back have gotten much slower. (via mapped drives to window machines) In the uprading of the new DSM, we added Cloud Sync server backups to dropbox, which syncs automatically. We thought this was the culprit for awhile, until recently we just upgraded our upload speeds by 20x. the server is still disappointedly slow. we would like someone of expertise to teamviewer in and tweak it up, perhaps do some testing on why the speeds aren't where they should. Many threads of similar problems. http://forum.synology.com/enu/viewtopic.php?f=14&t=92886 http://forum.synology.com/enu/viewtopic.php?f=14&t=83419&start=30 http://forum.synology.com/enu/viewtopic.php?f=14&t=100508 can work via teamviewer.
