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 expirations, and user notifications.

Most notably, we developed a framework-agnostic implementation of the saga pattern we named the Saga Engine to orchestrate transactions and compensating actions across multiple microservices.

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.

To do so, 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.

We designed a simple trading platform for our SMU-X sponsor — Credit Suisse.

Given multiple core functionalities in the requirements, we used microservices to reduce the complexity of each component and enable developers to work semi-independently.

We also developed a simple ML-powered stock recommendation engine.

For our efforts, we were awarded the Best Technical Team achievement.

Simulation of Voting Fairness in Singapore

CS426 Agent-based Modelling and Simulation

We modelled various gerrymandering and Group Representation Constituency allocation strategies using an agent-based simulation to explore the impacts of voter flexibility and distribution on the fairness of representation.

Network and Link Layer Emulation

CS441 Network Security

We emulated a simplified version of the MAC and IP protocol on top of network sockets for our physical layer.

With the emulated network, the project requires a study and implementation of IP spoofing, IP filtering, and packet sniffing. Our group went beyond the requirements to implement private and public network separation, a simple public routing protocol, the ARP protocol, and IP traceback.

Optimizing Hotel Bookings

CS421 Introduction to Machine Learning
  • Python Python
  • scikit-learn scikit-learn

We analyzed data on hotel booking demand and explored a variety of machine learning techniques to predict the cancellation of a given hotel booking based on pre-existing features.
