Mirapoint sold Email, Security and Archiving solutions on an Appliance model. As a Senior Engineer I had responsibility for Third and Fourth line support of the entire product range, from the Linux kernel up through the services to the applications and user front-ends. The role required an ability to troubleshoot customer issues from a general symptom to a solution, be that a configuration switch or a particular line of code. In some instances it is necessary to develop and deploy patches. To do this an in-depth knowledge of all aspects of the systems is required. This includes areas such as:- Storage management - local, NAS and SAN.- Networking - interfaces, configuration, protocols. - Services - SMTP, LDAP, SNMP, NDMP, DNS- E-Mail Security Features - AntiVirus, AntiSpam, Reputation systems, Greylisting, Blacklists, Authentication, SSL, DKIM, SPF- E-Mail Protocols and API's - SMTP, IMAP, POP, XML, HTTP.- Scripting and Programming - Shell, Perl and C, C++.- Use of development tools - Perforce, Subversion, Cscope, make.- Databases - SQL, SleepycatFurthermore I developed and delivered training materials to strategic customers where a more focused, technical approach to training for the customer's environment was more appropriate than a generic training course.

Development of Secure Messaging environments.Deep knowledge of SMTP and X400 as well as LDAP and X500 directories was required to develop custom solutions for SC Cleared projects to tight deadlines and pinpoint QA testing.Most development work was done in Perl and Visual Basic, pulling, modifying and pushing directory information around multiple platforms. I was also heavily involved in the QA process, developing the test criteria and executing them.

From leaving university I worked my way up as a self-employed IT contractor from desktop support to enterprise email and Linux systems engineer. Along the way I worked with everything from DOS to AS400's, Netware, Active Directory, HPUX, OpenMail, MS Mail, Exchange, Domino, IPX and TCP networks, telecoms and much more. I worked in finance, services, government, health, technology, systems integrators, manufacturing and other sectors. Some of my employers included BT, Shell, the Dutch Foreign Office, most of the large SI's (HP, Fujitsu, EDS, Perot etc), British Aerospace, Barclays, Santander, UBS, Clerical & Medical and more.I supported networks and applications, wrote database apps, scripts and tools, trained other staff in what I knew, performed hardware maintenance and was everything from a one man IT department to part of IT departments numbering in the hundreds. I've done everything from fixing a printer to debugging a multi-layer, multi-path storage stack.
