I worked at Grab in Singapore, first in the GrabFood division and later across the wider Deliveries organization.
Senior Software Engineer (2021 – 2025)
- Worked in the Deliveries organization on creating and enhancing gRPC and REST APIs and microservices that manage food and general delivery (express) orders from creation to completion, at a scale of more than 2 million orders per day.
- Built a Python automation that analyzed AWS infrastructure spending patterns and used ML algorithms to highlight services with anomalous cost increases, then tuned the infrastructure of those services — reducing AWS infra cost across 7 microservices in my team by 30%.
Software Engineer (2019 – 2021)
- Designed and implemented a partner-wise food-order-data streaming and collection pipeline used to share food-order data with big partners across all countries on a daily basis (Kafka, SQS, REST APIs).
- Recognized twice as an employee who went “Above and Beyond” to deliver value to the firm (Feb 2020, Nov 2020).
