Senior Web Developers for Big Data Web Application

We looking for experienced software engineers who have expertise in PHP and advanced databases to take over the Lead Development of a web application based on patent data.

Sofar, we have started using Laravel as a framework and Postgres as database. Other technologies welcome if there are good reasons to change those.

The web app is based on over 100m patent documents which need to be queried efficiently in order to allow search functions and create profiles of patent law firms and patent applicants filled with information from the extensive patent database. Profiles need to be dynamic, i.e. filter functions change displayed visuals without reloading the page by clicking on visual elements like pie charts.

The database is setup already.
