Technical / Project Management: Unix System migrations.

Key senior technical project role as part of team migrating Solaris and  HP-UX (10 and 11) billing/mediation systems to Dublin from the UK.  Role involved assisting with system analysis (discovery) and design, coordinating and project managing the initial O/S builds by remote teams in Dublin and Germany. Introduced a new check-system for monitoring RAG status of system build tasks which was then also used by subsequent projects. Also responsible for reporting in regular management meetings. Technically I performed hands on clustering (VCS), filesystem creation, mirroring , performance tuning and optimisation (VxVM and VxFS), scripting (korn shell), DiskXtender data migration, backups, documentation. The Mediation system migrations were successfully implemented both on time and under-budget for which a bonus was earned.
