#1 about 3 min

The journey from one to many mobile applications

The need to scale transformed a single mobile application into five independent products over five years.

#2 about 2 min

Choosing React Native for mobile application growth

Team experience and cross-platform capabilities made React Native the ideal choice for rapid initial development.

#3 about 3 min

Building the initial news portal application

Developing the first news application required establishing robust platform features like notifications and offline caching.

#4 about 6 min

Approaching the scaling challenge of a second product

Tight deadlines for a second product forced the team to evaluate monorepo setups against code duplication.

#5 about 4 min

The performance cost of overloaded interface components

Forcing shared user interface components to manage divergent business logic caused severe scrolling and rendering bottlenecks.

#6 about 5 min

Maintenance overhead across multiple divergent code repositories

Managing three disconnected repositories turned framework upgrades and persistent bug fixes into a severe maintenance bottleneck.

#7 about 5 min

Extracting business logic to rescue application architecture

The team halted feature development to redesign interface components to pull data exclusively from external view models.

#8 about 3 min

Implementing layered shared infrastructure for multiple products

A layered architecture approach successfully consolidated five separate portals into a single shared deployment pipeline.

#9 about 5 min

Evaluating tooling alternatives and optimal repository setups

Tooling alternatives like Expo and architectural benefits of monorepos offer different trade-offs for scaling applications.
