Particularly skilled at optimizing hardware installations, Software Engineering, Systems Administration, scripting and automation. Uses an analytical approach to create solutions that are well-engineered, that provide a solid foundation for future change, and that replace complexity with elegance. Key Skills Developing well-engineered solutions that are right first time due to attention to detail and meticulous planning Delivering stable I.T. systems that support and enable business changes Creating stability with standards, consistency and automation Creating savings and optimizing efficiencies through the effective use of technology Building trusting relationships with suppliers, customers and colleagues at all levels Achievements Accelerated the adoption of DevOps tools by the team by means of mentoring, and by demonstrating their use by effectively and rapidly deploying new systems. Reviewed the deployment process to identify areas of high risk, then worked with the Developers to created an approach that, in the event of a problem, permits a proven and rapid recovery. Also, reduced complexity and increased automation. Re-engineered a publishing process so that it became simpler, reliable, easier to maintain, included monitoring, and formed a firm foundation for enhancements. These improvements immediately allowed the de-commissioning of a Unix server with high support costs, and reduced the time taken to add new content by 75%. Migrated an existing key business system into a new environment over a single weekend, at all times being able to restore the original system in the event of system failure. Created a new interface application to replace existing hardware and software under the constraints of aggressive timescales and a financial loss of 200,000 (in extra leasing costs) if the deadline was missed. Automated the most frequently executed Service Desk procedures, with a consequent 66% reduction in the cost of handling these calls and a 90% reduction in the response time to these calls.
