Experience

Senior Software Engineer — Greenstone Financial Services
Mar 2026 – Present
Own feature delivery and platform observability across customer-facing insurance and financial services portals serving tens of thousands of users.
  • Deliver most feature work with coding agents (Claude Code, Codex, GitHub Copilot), applying established planning and implementation patterns while managing context quality and model cost
  • Hold AI-written code to the same bar as any other change (TDD, type and lint gates in CI, code review), using MCP integrations to give agents the project context needed for planning and implementation
  • Led adoption of OpenTelemetry, OpenFeature (with LaunchDarkly), and Storybook, enabling end-to-end observability, progressive feature delivery, and component development with a visual-regression testing layer
  • Consolidated observability into Datadog (logs, metrics, traces, RUM) for unified system visibility
  • Improved the E2E framework to run in ~2 minutes by spinning up ephemeral environments in CI, bypassing third-party auth, caching sessions, and parallelising test execution
  • Built a self-service test-data API into the pre-prod login flow, replacing manual DB access and becoming the organisation's default entry point to test environments
  • Moved the team to routine business-hours deployments, making out-of-hours releases and manual production validation the exception rather than the norm
Senior Software QA Engineer — Greenstone Financial Services
Mar 2025 – Feb 2026
Owned test automation strategy, frameworks, and test observability across customer-facing portals.
  • Designed and implemented a Playwright end-to-end testing framework replacing legacy Selenium
  • Integrated test framework into Azure DevOps pipelines for release-gated automation
  • Built custom Teams notifications and observability dashboards for test outcomes
  • Implemented visual regression testing for large-scale dynamic PDF rendering
  • Built API automation using generated OpenAPI clients to improve onboarding
  • Authored RFCs and engineering proposals covering continuous delivery, canary deployments, and test observability
  • Led workshops and pair-programming sessions to uplift QA and engineering teams
QA Automation Lead — Simpology Australia
Mar 2024 – Jan 2025
Led company-wide automation strategy, roadmap, and platform implementation.
  • Defined organisational test automation strategy and rollout roadmap
  • Built Playwright E2E and Postman/Newman API frameworks with CI/CD integration
  • Drove shift-left testing and improved application testability with developer collaboration
  • Migrated legacy Cypress/Selenium suites and implemented infrastructure automation
  • Embedded observability and business metrics for ROI and quality reporting
  • Mentored and upskilled manual testers into automation engineers through workshops, pairing, and documentation
Senior Software QA Engineer — DroneShield
Oct 2023 – Mar 2024
Owned QA automation and release quality for distributed systems and hardware/software integration.
  • Designed and maintained automation frameworks in CI/CD pipelines
  • Improved frontend and integration test coverage across complex distributed systems
  • Partnered with engineering teams on risk-based test planning and release readiness
Senior Site Reliability Engineer — Rokt
Feb 2023 – Sep 2023
Led reliability initiatives across cloud-native services with incident management ownership.
  • Led high-severity incidents through investigation, mitigation, and resolution, and facilitated incident-management training across teams
  • Implemented SLOs and tuned alerting strategies to reduce operational noise
  • Drove service-catalog ownership models, reliability scorecards, and service tiering
  • Supported full continuous delivery: releases gated only by automated tests, rolled out via Argo Rollouts, and monitored in Datadog with automated rollback
  • Built automation and tooling in Go, Python, Bash, and Terraform across AWS and Kubernetes
Senior Software Engineer (QA) — Rokt
May 2021 – Jan 2023
Built multi-language quality platforms for functional, contract, visual, and load testing across a 100+ service ecosystem.
  • Implemented Pact contract testing across more than a dozen services in multiple languages
  • Rolled out visual regression testing, reducing customer-reported UI defects and enabling safer CI/CD deployments
  • Built k6 performance and load testing for experimentation and production traffic replay
  • Delivered company-wide training, demos, and framework handovers; received the company-wide 'Hidden Value' award
Software Engineer (QA) — Rokt
Feb 2020 – May 2021
Built automation for microservices and ML-adjacent systems in an agile delivery environment.
  • Implemented functional, integration, and contract test coverage
