Software people depend on, from tax filing to grocery checkout.

Profile

Senior software engineer with 11 years building web and mobile apps for tax filing, banking, healthcare and grocery e-commerce. At Ringler Informatik I lead front-end development and stay hands-on in the code, shaping the product design roadmap with our designers and CEO and setting standards for architecture, accessibility and performance.

I began at Idean, a California design studio now part of frog, then worked in London for Nationwide, Sainsbury’s, a health-tech start-up and a fintech scale-up. Along the way I helped migrate Sainsbury’s grocery site (around 370,000 orders a week) to React with no downtime, and shipped mobile apps in React Native.
