• Bazaar provides B2B retail distribution across Pakistan with the help of five 5 apps that
• are Bazaar app, Khataa app, Agent app, Shipper app, and Warehouse app.
• As the head of the Devx-apps team, I oversee the modularization of five applications,
• maintain comprehensive unit testing, integrate advanced static analysis tools, establish
• efficient CI/CD pipelines, and construct vital components such as network, UI, widgets,
• analytics, and utility modules. Additionally, I supervise the development of feature
• modules that are leveraged across multiple apps.
• We created a modular architecture that features a plug-and-play design, supporting the
• idea of micro-frontends. This structure allowed us to establish a feature-focused team,
• centered on autonomous modules such as payment, lending, onboarding, identity,
• newsfeed, airtime, and others. Under this setup, the application serves as a container
• for these modular components.
• Developed a shared network module that serves all applications. This module is
• responsible for setting up interceptors, Moshi JSON adapters, authenticators, and
• certificate pinners with the OkHttp client. It also manages connection errors,
• authentication tokens, and refresh tokens through a session manager. The module
• employs Flipper and Chucker for logging purposes.
• Developed a newsfeed module that displays the latest news and promotions from the
• Bazaar, as well as live cricket scores during the Pakistan cricket tournament.
• Constructed a Game module that allows customers to play and win coins after making
• a purchase. The module displays a spinning wheel, and upon spinning, it reveals the
• winning coins that the customer can redeem to purchase items.
• Built AWS pipeline with Codebuilt to run sonarQube, unit test, UI test, and share build
• internally and after approval deploy the build to Playstore.
• Upgraded all the projects to Kotlin 1.7.10, gradle 7.0, OS target support to 32, and all
• dependencies to the latest versions.
