Robin visitor management: expected visits with host, visit type and check-in (product image, robinpowered.com)

Problem

Robin is a hybrid-workplace platform used to book desks and rooms, manage visitors and run the office. Features span a React/Angular web app, a React Native mobile app, an Outlook add-in and a fleet of Node.js microservices behind a federated GraphQL gateway.

What I built

Developed the Robin web and mobile applications in React, Angular, React Native and Node.js.
Contributed to the federated GraphQL gateway (Apollo Federation): custom queries, mutations and resolvers unifying the Reservations, Users and Devices microservices; cross-service schema composition, permission handling and token validation at the gateway.
Lead developer and owner of Visitor Management workflows, Anonymity Mode (user privacy) and the Priority Booking Window policy.
Led development and rollout of the mobile push-notification system; developed and maintained the push-notification and visitor-management microservices.
Owned production quality of the Microsoft Outlook add-in: weekly metrics reviews, Sentry instrumentation and Datadog dashboards.
Facilitated agile ceremonies, maintained engineering documentation and organised the internal hackathon three years running (1st place once, 2nd once).

Result

The mobile push-notification rollout increased monthly active users by 15%. Production errors on the Outlook add-in fell by 70%. Visitor management, Anonymity Mode and the Priority Booking Window shipped to Robin's customer base.
