PEAC/Portalsphere
Chief Technology Officer & Chief Technical Architect
June 1993 – July 2001 (98 months)
Mr. Greis was the founder of PEAC which provided advance technical training and consulting services. The business eventually employed 20 people full-time and had revenues of $3 Million/year. PEAC was renamed to Portalsphere upon completion of the mobile platform product and switched to a product-based operation. Portalsphere was sold to InBusiness Solutions on August 2001.
During the evolution of PEAC, Mr. Greiss architected, designed and wrote the majority of what became the Portalsphere Application Server. The product was eventually introduced to several Fortune 500 companies including; Alcatel, Bell Mobility, and the government of
The Portalsphere Application Server, is a distributed object-oriented high-performance applications server which includes support for wireless mobile devices as well as for SOAP clients and extended XML support. Both UNIX and Windows 2000 versions of the product were developed and deployed.
The Portalsphere Application Server was designed as a turnkey software middleware solution, responsible for the gathering, filtering and dissemination of information in a safe, effective and secure manner from a variety of sources including:
· all major relational database management systems, via native call interfaces and/or ODBC,
· XML formatted documents,
· LDAP access to information stored on an LDAP Server,
· hierarchical file and document systems, including UNIX file systems, networked file systems (NFS) and Novell file systems,
· legacy applications, including UNIX terminal based applications, IBM VM and/or MVS 3270 based applications,
· customized access to non-traditional data sources, via the customization features of the product
The PortalSphere Application Server unobtrusively sits within a TCP/IP based network within an organizations networking infrastructure, as a peer host system. It is also includes an Administration and Monitoring Facility for easy setup and administration, full-fledged session/user monitoring, and session tracing.
Scripting engines were developed for all of the most popular scripting languages. This allowed creation of Business Rules objects that could share data and status information. The object orientated design also allowed; the reuse of the business rules objects, the quick integration of new requirements, and provided a Rapid Application Development (RAD) environment.
One of the unique features of product was its support for multiple client interfaces including: browser based clients, thick clients and wireless access clients. Applications developed using the PortalSphere Application Server can be accessed from multiple client tools using a variety of access protocols.
Mr. Greiss also architected and implemented wireless applications for the RIM J2ME-based Blackberry devices as well as the Nokia Symbian based series 60 phones. These applications included a secure wireless IMAP based e-mail client, a real-time stock quote retrieval system and a database query client used to provide wireless CRM access to SalesLogix.
After extensive researched into the addition of security primitives within the application server, Mr. Greiss architected and designed support for a variety of private key block ciphers, public key ciphers, hashes and message digests, random number generators and X509 certificate management objects. He also added high-level scripting wrappers to facilitate the use of the primitives.
In addition he implemented:
· support for native access to a variety of RDBMS systems including Oracle, MS SQL, DB2, MySQL and PostgresSQL;
· support for LDAP;
· several scripting engines such as Tcl, Perl, Python and server-side JavaScript;
· an embedded Java Virtual Machine, thereby directly supporting Java clients.
The development environment for the PortalSphere product included UNIX, LINUX, Windows NT, Windows 2000, CORBA, COM/DCOM, SOAP, HTML, JavaScript, Java, C++/C, Tcl, Perl, Python, Oracle, MS SQL, MySQL, DB2, Postgres, GDBM, Macromedia Shockwave, Flash, Rational ROSE/UML/Booch/OMT, Entrust, Verisign.
As Chief Architect and CTO, Dr. Griess was responsible for selecting tools and methodologies, implementation and ensuring compliance with corporate:
· configuration management policies
· quality assurance systems
· CASE tools and environments
· Software test plans and methodologies
· Object orientated technologies and architectures
Mr. Greiss’ software development expertise in the areas of computing languages, methodology and distributed processing is reflected in both the Portalsphere platform and over 300 training assignments to companies such as; Newbridge, Pratt and Whitney, Nortel, HP amongst others. A sample of these can be viewed in any of the 60 videotapes produced and distributed by Keystone Learning Systems.
