Hired to plan and build from scratch Rubix – a Web-based logistics platform hosting various applications used by Woolworths delivery workers and contractors.

Rubix#

• Rubix and its first application, OTA Tracker, were released to production within the first six months.
• Built a library of core controls and services, with testing and deployment infrastructure.
• Used Figma to single-handedly design early prototypes of Rubix.
• Set up Nx-based mono-repo and SingleSPA based micro front end.
• Set up CI/CD pipelines, hosting setup and DNS routing in Azure.
• Integrated with Woolworths Active Directory for authorization using Keycloak Angular adapter.
• Migrated team to new mono-repo with minimal disruption.
• Optimised CI build+test time down to < 5 minutes per app.
• Multiple teams built on the Rubix platform and Rubix runs 6 apps, with 16 developers across 3 teams.

On-Time Arrival Tracker (OTA) app#

• Used Web Workers, sparse array pattern and Angular CDK virtualised scrolling for fast, efficient scrolling over massive realtime driver data.
• Prototyped iOS version of the app in Swift/SwiftUI.

Street Service Time app#

• Built a geographic polygon tool for recording service times at a street level (using LeafletJS and integrating OpenStreetMap and other providers).
• Performed comparison of mapping services to find optimal combinations of price and capability and presented findings to senior stakeholders.

Front End Chapter#

• Provided mentorship and leadership within the WooliesX Front End Chapter
• Prototyped enhanced search component using neutral nets (using BrainJS)
• Prototyped component-level automated visual regression diff testing (using Playwright)
