On a recent visit to a neighbourhood small provision shop selling essentials, we observed the solo shop owner shouting and struggling to enforce safe distancing measures. There were 15 people in 2 small aisles when there should have been no more than 4 people at one time in the shop.

Post Circuit Breaker, when normal economic activity resumes, we will see increased people flow and crowds in various locations. How do we ensure safe distancing while businesses of all scales and sizes conduct their normal activities?

Our co-founder Medha realised we needed a solution to control people flow.

To find out more about the solution, use cases, benefits, deployment options and platform API capabilities, please refer to our slide deck and video demo above :)

How we built it

Our goal was to build safe distancing platform APIs that can enable on-demand quick deployments of virtual queuing service in many custom scenarios.

One sub-team worked on the back-end APIs, written in Java and SQL. Another sub-team developed user-facing Android apps to rigorously test the APIs and ensure all use-cases work and also managed cloud infrastructure activities.

Challenges we ran into

We faced a steep learning curve to understand and leverage the capabilities of the Google platform and implement a proper security model.

Accomplishments that we're proud of

We have a Minimum Viable Product (Version 1) available today. It is ready for customer trials and deployment.

What we learned

We have learned a lot about the technical capabilities of the Google Cloud Infrastructure including APIs, Google Security Model and Android App Development.

What's next for qSafe

  • Partner with organisations like GovTech and Google to drive deployments in Singapore and other countries
  • Harden the platform further for large scale deployments
  • Integrate with existing platforms like SafeEntry through APIs where required
