We are a mobile platform that will allow people to comprehend, in a matter of seconds, the ecological and human impact of their grocery lists. At LeafValue we aim to become an outright integrated enrichment to the grocery shopping experience itself. By including functions such as a price comparator, nutritional and allergenic facts and primarily Sustainability Evaluations we want to create an all rounding complement for consumers. But much more than the common Start-Up looking to make money, we truly aspire to make a positive impact on our environment and in a highly criticisable industry. We seek to increase the consciousness of consumers towards the disturbing practices that some food providing companies/coorporations have (such as child labour, illegal deforestation..etc) and therefore the environmental and humanitarian repercussions that buying those products have. Ultimately we aim to promote a globally higher and sustainable standard throughout the food industry We are looking for a single or a group of experienced and professional app developers that will help us create an iOS Application for Iphone. Expertise in Objective-C and an outstanding sense of design and functionality are priority skills we are looking for in a developer.

We highly value a genuine interest, engagement and enthusiasm in a candidate and place big importance on the quality of the dialogue that we will want see in our team. If you want to be part of our project do not hesitate and contact us. Good wishes, always, Dan

We are running a single Percona database on EC2 and separate instances running PHP Symfony application threads to concurrently fetch jobs from a queue table. There are about 30 million records in the InnoDB job queue table, and it could be as high as 100m. The PHP app takes many seconds to choose a job - longer than a job takes. This 30m job queue is estimated to take 15-40 days. I need a very experienced DBA to diagnose the bottleneck(s) on this *production* server. Interruption of several minutes is acceptable but not more. The guy who designed the tables is pretty experienced, the queries and indexes should be sane, the hardware is pretty good - I can't see any quick wins. Amazon CloudWatch suggests hardware limitations are not hit (nowhere near). I have made some basic InnoDB tweaks, for better or worse I am not sure, but now I am out of my depth :) I am also keen to do future work with the right DBA - replication and backups, tuning, and generally turning this into a spiffy stack.
