Message

At Travelex, I helped launch a white-label travel money app for a tier-1 retail partner and engineered enterprise app variants with shared code and custom branding. I also improved Travelex Plus and optimized international money transfer flows.

At WorldRemit, I worked on a cross-platform app rewritten in React Native and led features including Refer A Friend, dynamic forms, and transaction annotations. I also led development of Google and Apple Single-SignOn to increase mobile signups.

At Integrate, I reduced app size by 15% by re-architecting the app with my team, and cut feed-screen RAM usage by over 40% with performant components. I implemented CI/CD and supported offline use, accessibility, and cross-platform deployments.

Earlier, I migrated Piggyvest’s legacy webview app to React Native and developed features for authentication and savings. I’ve also built app experiences at Paddyme and developed a Unity3D game called Sweeply.
