Legacy rescue at 1.8M-learner scale
Led front-end development and rebuilt a legacy platform used by 1.8M learners for one of the world's largest education publishers (client under NDA): refactor, automated tests, Backbone → React with Redux/Saga, and the customer in every Scrum call. The company had written the project off as non-profitable; it became its main income stream.

Investment Bank Deal Platform
Compliance-grade UI for high-stakes data
Deal-processing platform for one of Australia's largest investment banks. Arrived as team lead over three developers, replaced two of them, and grew the delivery organisation to 30 engineers across six frontend teams, coordinating QA in India, backend in the US, and the client and management in Australia. Negotiated the growth with the client as a business case, owned hiring, Scrum, environments and CI/CD, and stayed top contributor by commits until the team passed six or seven. Then handed it over to a manager I hired and went back to engineering.
