Experience Summary
With over 20 years of hands-on experience in enterprise architecture, cloud solutions, and application development, I have successfully delivered enterprise-wide integration solutions using SOA, RESTful APIs, microservices, and event-driven patterns. I have led Agile architecture initiatives aligned with the NSW Education Digital Strategy and have designed and implemented reusable frameworks and reference architectures to support ICT governance and cybersecurity compliance.
My expertise spans multiple cloud platforms including AWS, Azure, and GCP, where I have architected scalable, secure, and maintainable solutions. I have strong experience in middleware and integration platforms such as MuleSoft, TIBCO, and Oracle SOA, and have led integration strategies using standard patterns and best practices. I have designed comprehensive solution architectures based on business requirements, integrating complex enterprise systems such as ERP, CRM, and HRIS platforms.
I possess deep technical proficiency in Java, Spring Boot, and serverless development using AWS Lambda and API Gateway. I have developed microservices with Kubernetes and OpenShift, implemented DevOps pipelines using Jenkins, GitHub Actions, and CircleCI, and automated deployments across hybrid and multi-cloud environments.
In addition to core development, I have worked extensively with SOAP/XML web services, designed and managed APIs using RAML and OpenAPI specifications, and ensured secure API management using tools like AWS WAF, OAuth, and mutual TLS. My contributions also include significant database expertise across Oracle, MySQL, PostgreSQL, SQL Server, and NoSQL databases such as DynamoDB and MongoDB, including schema design, migrations, and optimization.
In data and analytics, I have built scalable pipelines using AWS Glue and Athena, delivered enterprise-level dashboards with Power BI and Azure Synapse, and integrated reporting with Google Looker Studio and GA. My technical acumen is complemented by strong stakeholder engagement and communication skills, working across business analysts, program managers, school leaders, and vendors.
I have also driven innovation initiatives introducing technologies such as Apache Kafka for event streaming, Elasticsearch for log analytics and search, and developed internal reporting solutions using open-source PDF reporting frameworks. I am committed to continuous learning and possess certifications including AWS Solution Architect, Certified MuleSoft Developer (MCD Level 1/4), and have undertaken training in enterprise integration and architecture governance frameworks.
