Portal Solution with IBM Websphere Portal

IBM’s WebSphere Portal is recognized as an industry leading solution used by companies large and small. As an IBM Advanced Partner, Rexintegra Ltd has been involved with IBM WebSphere Portal since the year 2007, helping customers create solutions to support complex business challenges. The portal provides custom-branded, enterprise capabilities that help deliver a highly-personalized, social experience for customers and employees. With WebSphere Portal, you can give customers and employees a single point of access to the applications, services, information and social connections they need.

Rexintegra Ltd created and integrated a global portal for a 12B+ employment services company and ranked on the "Fortune 500" list of America's largest companies. The system is based on IBM’s WebSphere Portal, it is multi-functional and multi-language. The portal encompasses all internal processes for processing and maintaining job candidates’ information. The portal has two major integrations: with a resume scoring/indexing engine – CVs are being automatically evaluated and matched against set of requirements and the client’s back office management solution – a complex system including candidates’ database and encompassing all back office activities the recruiters perform.

Portal Solution with Drupal

Rexintegra Ltd designed a multifunctional portal for one of the top 10 universities in Bulgaria. The university needed a multi-lingual portal site to provide the students with access to all necessary information related to their education.

The site is also intuitive and easy to use by the people, responsible to keep the content up to date. It is integrated with several existing systems – for courses scheduling and information about the teachers and their publications. The integration allows information from the in-house developed systems to show on the university public website.

Mobile Job Search Solution with iOS

The mobile job search application was developed for a 12B+ employment services company, ranked on the "Fortune 500" list of America's largest companies. It is the staffing industry’s premier tool to search jobs, apply for career opportunities, locate branches and get the best career news content on the web. This app helps users to quickly search for the job of their choice through keyword or category searches and easily sort results using Google Maps or scrolling features. The app also utilizes the phone’s geo-location capabilities to enhance the search process. Rexintegra Ltd implemented the iPhone application along with the services layer that allows iPhone app to function. All data is stored in a database and accessed through REST web services built on top of IBM Websphere Application server 8.0.

Mobile CRM Application with SenchaTouch

Rexintegra Ltd developed a mobile CRM app for a Fortune 500 drug manufacturer – one of the oldest biotechnology companies in the world with more than $5 billion in revenues that discovers, develops, manufactures, and markets biological products for the treatment of serious diseases. The company’s objective was to mobility enable (“mobilize”) its global sales force of over 1,000 pharmaceutical sales representatives. Each pharma rep was given an iPad in order to take advantage of the device’s presentation capabilities during client visits (calling up marketing collateral) and to increase sales productivity while on the road (working within a customer relationship management tool). The challenge was connecting the iPads to the company’s existing backend applications portfolio, in particular to Oracle CRM on Demand, a heavyweight CRM implementation which is centrally hosted at the company’s headquarters and in turn is integrated with a host of other systems. Oracle currently does not provide a mobile version for its CRM product and offers only a limited browser version which was determined to be insufficient for the firm’s notion of effective field sales enablement.

Rexintegra Ltd addressed that challenge by devising and developing an innovative hybrid enterprise app for iPad that two-way syncs with Oracle CRM on Demand and allow the pharma reps to work in “offline mode” (while traveling say on a train or meeting a physician in a shielded hospital environment).

The business requirements being implemented are:

  • Call Planning
  • Pre-Call Preparation
  • Call Recording and Reporting
  • Time Tracking/Time off Territory
