Development of technical test concepts for the High Availability mechanisms in a large web and email platform, with architectural input into the failover strategies for the mail store backends

Designed, implemented, tested, and executed a Highly-Available Rollout strategy for a complex Java application (web services and workflow engine with data replication and distributed in-memory database). Due to the large structure of the organisation, the procedure involves co-ordinating the communications between 3 teams during the rollout.

Designed, developed and tested systems for receiving, parsing and processing orders and invoices in the EDIFACT and TRADACOMS dialects of EDI.

Designed, developed and tested a server daemon providing network access to a collection of software libraries querying a legacy ISAM database

Developed the backend to a dynamic discussion-board website with multimedia functionality, where video files are converted automatically into FLV format (Flash) after uploading and made immediately available for viewing via the site

Developed the backend to a dynamic website with CMS for book wholesaling. Books can be searched for by all possible bibliographic details; orders are fed automatically into the company's internal system. Customers can query the status of their orders in real-time and download dynamically-created MARC files containing bibliographic information.

Designed and developed the backend for an instant-messaging system, with IRC-like chat functionality. Communication between clients and server was implemented with a custom-developed XML protocol.

Designed, developed and tested a network protection system which reads the system logs and automatically manipulates the server firewall rules to close off attacks when attempted misuse of various ports is observed.

Design, automation and execution of technical test concepts for a Siebel application containing 10 million+ customer records, including data-cleansing SQL scripts.
