Project Description We would like to implement HR, Finance and Sales in our cloud so that the customer would open www.companyname.net/erpandcrm ,subscribe and get the benefits out of the erp/crm in minutes. Technical Requirements Architecture: As existing cloud infrastructure is redundant, we will use one server for Web and one server for Database. The solution should be scalable so that we can distribute load the in the future. Each customer would have his own database. Security is crucial, so cloud multi-tenant is a must and total isolation amongst customer is a must. Https would be used. Each customer would be defined using the domain name, such as info@xyz.com and sales@abc.com and the domain name would distinguish customers. Modules: We will use the latest community edition. We will use all modules related to HR, Finance and Sales. In the beginning, we will use Odoo (or others could be OK) as is with no customization. However, any customization should be easy and we would recommend to use Parent and Child module so that upgrade, install and customization are easy. Please suggest if we have better idea. we need to find a way to manage future releases. Feel free to suggest ideas. User Management System: An administrator should be able to create, delete, reset password and have total control over the user. Billing System. Billing System should show each the billing cycle for each user and report invoice. Mobile App: in the future, a User should be able to login using mobile app in order to check certain features. So generating API is a must

Server Specifications: We are using Openerp 7.0. The server is running on dual 10 core xeon processors with 20gb ram and a SSD directly attached RAID 10 storage array. Basically put, the fastest possible performance that you can get. So that we can rule out any hardware issues. Background: I am trying to resolve performance issues, created either through poor programming or design in Openerp Version 7.0. The successful applicant, if they can solve the problem will more than likely get a lot more work as we have several performance improvements flagged for development. The task: Improve the speed of applying a payment to a supplier invoice. Please either improve the speed with the function working in exactly the same way, or explain why the function is slow and propose changes to the process in order to optimise the speed.

Basic Goal of the project: Implement the following services connected to a QGIS server (as a backend): - add new points (in bulk) to a typed GPS coordinate with some metadata (will be defined on time) - transform CSR: from a (X,Y) defined in EPSG:23700 (EOV) to (x,y) in EPSG:4326 (WGS84) - WMS service to provide basemap with the point freatures on it (QGIS server automatically provide this) - request a set of points in a territory, response the point details including the metadata - search a set of point which is near to a city (like near "Varso") - A minimal demo webclient would be great to include, you can use the QGIS-web-client (https://github.com/qgis/QGIS-Web-Client) as a starter project - test server will be provided with easy deploy using Docker. The architecture is not fixed, we are not sure wether it's required to add a middleware between QGIS and the webclient or not. Or you think the best would be to use PostGIS with PHP/NodeJS, isn't it? And get rid of QGIS? Your suggestions are welcome here. After the demo you can expect the project to move on the next phase by implementing some standard components: - user registeration, login, role handling (3 different type of group is specified), - connect the points on the layers to users - integrate a third-party payment provider - ...
