Kopi Time is a digital marketplace for coffee-related art and collectables.

We implemented a reliable and robust microservice architecture to handle:

• market trading functionality,
• listing timeouts and expirations, and
• user notifications.

We designed a highly available and maintainable backend architecure for our SMU-X sponsor — COMO Group.

Most notably, our architecture fails gracefully when third-party external services are unavailable.

We continuously check the health of external services. When an external service fails a healthcheck, we queue all client requests and notify users of the temporary disruption. Once the external service is healthy, we automatically trigger a recovery phase and continue with regular execution.

We conducted market research and discovered an unfulfilled niche for a comprehensive database and search engine for hawker food in Singapore.

Using this database, we developed a product, risk mitigation strategies, and a feature roadmap for future growth.
