Messaging Service for Push Notifications
Designed and implemented a messaging service to send push notifications to Android and iOS devices utilizing serverless Lambda architecture to handle spikes in traffic.
Replaced the third-party service Braze & Twilio by developing an in-house solution, reducing operational costs.
Worked with the mobile team to onboard consumers to the push notifications system.
DEFCON Alert State Service
Designed and implemented DEFCON, an alert state mechanism activated during critical platform failures (e.g., order placed but not visible to riders/restaurants).
Integrated DEFCON into key parts of the order journey, ensuring user flow could be halted during severe incidents (Sev0).
Utilized Kafka for real-time updates across services and S3 for configuration state storage.
Developed an intuitive UI enabling employees to activate DEFCON efficiently during high-severity incidents, providing swift response capabilities during high pressure scenarios
