Friday Hacks #139, October 6

Posted on by Herbert

This Friday, we have Hongyi from GovTech talking about the making and deployment of a Digital Parking App, and Mohammad from TradeGecko talking about Asynchronous Processing!

Date/Time: Friday, October 6 at 6:30pm
Venue: SR3, Town Plaza, University Town, NUS
Free pizza is served before the talks. from Prototype to Production

Talk Description: is an app to pay for street parking without needing coupons. Learn how the app was built from the initial prototype to roll it out island wide. We will talk about the product, engineering, and bureacratic design decisions that were made to get us successfully to launch.

Things we’ll cover include:

  • Pitching with prototypes instead of slides
  • Stripping away unecessary features so you can focus on what is important
  • Designing a data model for a distributed system
  • Reliable apps while having an unreliable network
  • Designing a clean user experience

Speaker Profile

Hongyi likes to build things. As the Deputy Director of the Product and Engineering Team at GovTech, his job is to design, evangelize, and implement software to help improve the public good. Projects he’s launched include,, and Prior to joining the government Hongyi worked at Google. There he designed the current Image Search “page split” UI and worked on Spanner: Google’s Globally Distributed Database.

Asynchronous Processing

Talk Description:

Asynchronous processing is an important methodology for systems design which allows execution of expensive calculations independently of critical/responsive system flows. In this talk we will be:

  • Walking through systems before/after asynchronous processing is introduced into their architecture.
  • Shedding the light on Asynchronous processing landscape (servers, frameworks, and libraries).

Speaker Profile

Mohammad is an Engineering Manager at TradeGecko. Through his career, he worked with multiple technology stacks and enjoyed testing out and experimenting many others. He worked both in the financial sector, where engineering performance & optimization is key, and in lean product development environments where user-centric design is a priority. In his free time, he loves to experiment with technologies and food (yes, he can make some interesting middle-eastern dishes). Some of the topics that excite Mohammad: Distributed Systems Design, Operations Research, Parallel Processing, Graph Theory, Queueing Theory, Database Design & Domain Driven Design.
