I have substantial experience in managing and supporting both non-production and production RedHat OpenShift Kubernetes clusters hosted on AWS and on-premise (VMWare). The clusters host critical integration services and applications across the digital and BSS/OSS domains. A significant part of my role involved working closely with development teams to design and implement CI/CD Tekton pipelines in OpenShift for application and web service development. I integrated these pipelines with tools such as SonarQube and Prisma to ensure thorough test code coverage and vulnerability scanning.In addition, I am responsible for coordinating, planning, and executing platform upgrades, production deployments, and database upgrades, with a strong focus on automation to reduce human error and enhance efficiency. Effective communication is vital to my role, and partnering with Service Management to ensures that platform changes are effectively communicated and business approvals secured.Security and compliance have been central to my responsibilities where I closely collaborated with security teams to enforce compliance and best practices. As an integral member of a project team, I contributed to the successful migration of integration services from legacy platforms to the OpenShift platform, ensuring a seamless and effective transition.Achievements:• Excelled in acquiring new skills in Cloud, OpenShift Kubernetes, pipeline management and automation, leading to a permanent role in the DevOps/Platform Engineering team.• Successfully migrated over 100 key integration microservices from legacy JBOSS and Websphere application servers to Red Hat OpenShift Kubernetes clusters. • Supported the launch of the Optus NBN integration platform, hosted on OpenShift, a critical project due to the decommissioning of NBNs ebXML interface. • Enhanced operational efficiency by automating platform & database upgrades along with application deployments.

As a DevOps professional, I am known for my adaptability and commitment to expanding my technical expertise. This drive led me to join the OpenShift Platform Engineering team where I quickly gained proficiency in Kubernetes and cloud technologies. I played a crucial role transitioning first-line support to a 24x7 operational vendor team. What started as a secondment evolved into a permanent position, where I assumed the responsibility for managing this business-critical platform as an integral member of the engineering team.

I was responsible for defining and implementing a comprehensive test strategy that aligned with the project’s unique requirements, objectives, and constraints. This position required active engagement with multiple vendors to ensure the effective delivery of testing services, along with regular communications with stakeholders regarding progress, challenges, and outcomes.Additionally I managed the testing budgets, ensuring the resources were allocated efficiently and that vendor testing quotes were reviewed and negotiated to stay within budget. My responsibilities included managing System Integration, Non-functional/Performance, User Acceptance, and Regression testing cycles. To improve testing efficiency and precision utilising test automation tools such as HP LoadRunner, JMeter, Postman, and SoapUI.Achievements:• Delivered test services for Layer 7 API Gateway as part of the SDP stack.• Delivered test services for Optus’s BCC (Business and Customer Care) program, a high-profile 3+ years transformation initiative. • Reduced vendor test costs by 10% to align with business KPIs• Reduced wholesale customer onboarding to under 2 weeks by providing a repeatable test framework.

Transitioning into project management broadened my role to oversee the full project lifecycle, moving beyond software design and development. This role required strong organisational skills, effective ability to manage resources, budgets, and timelines, and clear effective communication with stakeholders at all levels.I was responsible for presenting Change Review Board (CRB) proposals to gain approval for project expenditures, which involved articulating technical aspects to a varied audience, including both business and IT stakeholders. Additionally, I delegated tasks to team members and tracked their progress to ensure timely scope-compliant project completion.Maintaining transparent and consistent communication with project teams, stakeholders, and other involved parties was crucial to ensure alignment and promptly address any challenges. I continuously assessed risks throughout the project and implemented mitigation strategies as needed to minimise potential impacts.Achievements:• WAM (Web Access Management) Platform Upgrade which was the strategic web security layer used to manage the identities and access rights of both internal and external web users across Optus internal and external facing systems. Project required the migration of the Microsoft Active Directory to use CA Active Directory solution.• Test case management platform and Automation tools upgrade - Upgrade and migration of test cases and automation script to the latest HP Quality Centre and HP Performance Centre• CA ITKO Lisa integration - Integration of this ITKO software suite into testing environments to simulate services, APIs and other system components to help automate testing

I managed the development of Optus Consumer products, including OptusZoo, a mobile portal and service platform aimed at delivering a variety of mobile services and content to Optus customers. My role also involved expanding the development team's responsibilities to include providing integration services to other Optus divisions. This expansion contributed to the evolution of the Service Delivery Platform (SDP) / Enterprise SOA stack into a crucial technology framework, supporting provisioning, billing, prepaid services, and network integrations for both consumer and enterprise clients.Additionally, I was instrumental in designing and developing solutions for the expanding system integrations within the Service Delivery Platform.Achievements:• Delivered key functionality as part of the Service Delivery Platform used to service Optus Customers in provisioning, billing and network services

As part of a design and development team worked on projects to further enhance and develop new features for Openwave technology platforms and tools. These included SMSC and MMSC platforms , Unified messaging platforms together with Mobile Content delivery that optimised content for mobile devicesAchievements:• Broadened the mobile handset market that Openwave's content delivery platform and technology aimed to reach

I Joined Optus's newly established in-house development team, transitioning from an outsourced software development model. Leveraging my telecommunications experience from Ireland, I developed software solutions across various platforms, including Web, Mobile Web, SMS, USSD, and Push to Talk. This paved the way for the delivery of Optus's first WAP mobile portalAchievements:• Based on my skills gained in Ireland, I developed the first in-house enablement to allow the push of SMS messages to Optus Customers. Till that date, costly outsourced solutions were in place.• Launched Optus first WAP portal.

• Commenced my telecommunications journey joining a leading edge irish tech company, Aldiscon, specialised in Short Messaging Services launching the first commerical SMSC platform. After Aldiscon was acquired by Logica, Aldiscon Northern Ireland, was spun out into a separate company APiON Ltd. • As an engineer at APiON, designed and developed (using C programming) the first commercial Wireless Application Protocol (WAP) gateway. This pioneering technology laid the groundwork for today’s mobile internet. https://www.wapforum.org/new/Apion_Sonera.htm• Through the design and development of a WAP gateway, I gained valuable experience in programming in C , using Sun Solaris (unix-based operating system) and telecom protocols like SMPP to send and receive from SMSC (Short Message Service Centre). This experience proved to be a natural fit for a telecoms career after migrating to AustraliaAchievements:Part of a team who successfully designed and developed the first commerically available WAP gateway
