12/2001 – 12/2003

Working in the Energy(Gas/Electricity) sector, I took part in automation and management of Energy-Distribution by designing and developing various Internet/Intranet solutions, as well as desktop applications. Designed and developed custom systems to secure applications at code, database, and user interface levels. Developed complex COM/COM+ components, .NET-Assemblies, and B2B-Portals. Architecture of security concepts, encryption-, decryption-algorithms. Applications were developed mainly for OMV and EVN.
Some of most important projects accomplished at HAKOM:

Electronic Management of Data and Information System (eMDIS Project)
eMDIS was developed as an enterprise-wide software platform for administering measured and allocated energy consumption data. Every page of the presentation layer relays on an XSLT-Style Sheet and a dynamically generated XML-file.
Some later components of eMDIS have been developed using .NET technologies. The COM-Interop features of .NET have been extensively utilized to expose VB 6 components to .NET assemblies. Other technologies used were IIS 5.0, JavaScript, and COM+.

B2B-Portal (Online Ordering System) for RHI AG
RHI AG, based in Vienna, Austria, is a globally active industrial group with 130 production and service locations spanning five continents. B2B-Portal serves for internal ordering.

Universal Data Access Layer (DAL) for SQL Server & ORACLE
This solution makes data access independent from the type of database. An ORACLE database can be replaced with a SQL Server database and vice versa without any changes within applications. It required extensive use of abstract programming, inheritance, .NETs cloning Technologies, type conversions between MS SQL Server and ORACLE, and XML
