• Spearheaded the design of self-serve purchasing and provisioning pathways, running 35+ experimental rollouts and analyses that drove a 23% increase in purchases across 3 flagship products.
• Built an anomaly detection service (Koa, Splunk, Opsgenie) monitoring funnel metrics across 5 growth teams and 50–75 touchpoints, cutting mean time to detect regressions from 2–3 weeks to a day.
• Implemented comprehensive Jest unit tests and Playwright end-to-end tests, lifting coverage above 90% and reducing production regressions by 40% within 6 months.
• Defined and implemented SLOs with monitoring and response workflows, maintaining 99.9%+ uptime and reducing MTTR by 30% within 12 months.
• Partnered with Customer Support to debug production issues, led post-incident reviews, and shipped corrective action plans that reduced repeat incidents.
• Led feature performance evaluation with Data Science using SQL in Databricks and Amplitude dashboards, delivering executive-ready reports within 30 days that shaped rollout strategy.

• Built a highly configurable React.js component library for a server-driven UI platform, integrating a GraphQL configuration service to replace a legacy CMS and enable backend-driven rendering across product surfaces.
• Co-developed the Ad Controls package (React + TypeScript) for the Growth team, providing plug-and-play functionality across experimentation surfaces and ensuring dismissed ads never reappear across workspaces via a backend state and recommendation service.
• Automated internal processes with a Node.js service that generated Confluence documentation packs, reducing admin overhead and letting feature leads run experiments faster from a single source of truth.
• Authored technical decision documents (RFCs, DACIs, LDRs) that shaped team direction and standards, driving adoption of faster-maturing experiment metrics that cut experiment cycle time from 45 to 16 days.

• Developed and deployed features for a React Native mobile app and React.js web app serving 10,000+ customers and 350 businesses for real-time home-service booking.
• Implemented in-app purchases on iOS and Android and Stripe-integrated paywall components to monetise features, boosting revenue and retention.
• Built a Node.js webhooks endpoint (OAuth2) syncing customer data with third-party workforce-management systems and payment gateways.
• Created an end-to-end notification scheduling queue with BullMQ and Redis, and bash automation for continuous deployment on AWS Elastic Beanstalk and Lightsail.
• Deployed an open-source Grafana analytics server surfacing 50,000+ Amplitude data points, and built a RegEx phone-normalisation service for bulk cross-system data exchange.
• Documented R&D modules and applications that helped the firm claim an AUD $140,000 R&D grant.
