I worked from start on taw9eel.com project (I have great recommendation on linkedin from store owner). The biggest web site in Kuwait for online shopping. Big amount of order / big traffic / big impacts. A lot of different technologies we used, like SOLR search (for arabic and english store view), RabbitMQ message broker for async operation, creating pdf coupons (attachment in new order email). Also I worked on implementation two version of ERP. A lot of things and experience.
On project with me worked also Hrvoje Jurišić (fronted guy) and Krešimir Banović (backend guy)
