Experience
Software Engineer, Service to Service Fabric at Atlassian
Aug 2023 to Present | Melbourne
Building Atlassian’s Kubernetes-based microservice orchestration platform. The work spans Envoy proxy, Istio service mesh, eBPF networking, and the routing infrastructure connecting hundreds of microservices across Atlassian’s cell-based architecture.
- Contributed to the initial architecture and implementation of Atlassian’s service fabric controller, a Kubernetes-based microservice orchestration platform running at company scale.
- Led Istio service mesh adoption and pod-to-pod routing for Atlassian’s new cell-based Kubernetes architecture, serving Jira, Confluence, and their dependencies. Replaced a routing path where intra-cluster traffic traversed external load balancers unnecessarily, saving hundreds of thousands of dollars annually.
- Led HTTP/2 service-to-service communication and sharded routing via Envoy ext_proc, eliminating a central proxy bottleneck and delivering over $1M in annual cloud cost savings.
- Designed a HA failover solution for a mission-critical auth proxy service, improving resilience during platform and cloud incidents.
- Identified and resolved a critical Envoy DNS thread concurrency bug that had blocked Atlassian’s org-wide Kubernetes migration for 2-3 weeks. Separately found an Envoy TLS inspector bug causing ~1-2% of requests to hang on 16KB payloads; acknowledged by Envoy maintainers and fixed in v1.36.0.
- Appointed Developer Productivity Lead: pipeline optimisations and test flakiness reduction achieved 25-50% faster builds and improved the team’s “I can test my changes quickly and confidently” survey metric from 60% to 75%.
- Mentored an intern on a fleet-wide Envoy metrics migration, reducing CPU utilisation across Atlassian’s microservices by 5-10%.
- Unblocked a stalled OpenTelemetry metrics migration, moving Atlassian off a legacy metrics pipeline to a vendor-neutral OTel standard and reducing backend lock-in.
- Prototyped multiple ShipIt projects: an AI-assisted performance review tool, network extension isolation mechanisms, and a Kubernetes-native alternative to serverless workflows.
Senior Site Reliability Engineer at National Australia Bank
Jan 2022 to Aug 2023 | Melbourne
Primary escalation point for NAB’s API platform across Kong and Axway gateway environments on AWS and Azure.
- Designed and owned an automated SSL certificate renewal system for NAB’s API gateways, eliminating manual renewal and reducing operational risk.
- Built integration and unit tests for the legacy Axway API platform, and CI/CD pipelines for evidence capture, certificate management, and end-to-end deployment.
- Led incident response where NAB’s API platform was incorrectly blamed for a Visa outage preventing customers from onboarding cards to Apple Pay; identified the root cause on Visa’s side and unblocked resolution.
- Ran sprint planning and delivery for a team of 6 over a 2-month period without a manager.
Senior Systems Administrator at Intercontinental Exchange (ICE:NYSE)
Sep 2020 to Jan 2022 | Melbourne
- Led Python automation projects eliminating manual hardware fault management: automated fault discovery, change request generation, and remediation, significantly reducing production incident resolution times.
- Resolved a complex integration failure between ICE Data Services and Vanguard on a Solaris system through deep diagnostic investigation.
Systems Engineer at Tech Precision Pty Ltd
Jan 2019 to Sep 2020 | Melbourne
- Led consolidation of infrastructure onto VMware and Hyper-V hosts, and migrated Windows and Linux systems to Azure.
- Redesigned service desk workflows, reducing average open ticket count from 150 to 65.
