Context

Jazz Pakistan needed consumer and business self-care platforms built from zero—no existing mobile product to iterate on. Millions of subscribers would depend on recharge, billing, usage visibility, and account management across iOS, Android, and web. The product had to scale nationally while remaining intuitive for first-time smartphone users.

My role

I led end-to-end UX/UI as Senior User Experience Designer—owning research, personas, user journeys, wireframes, prototypes, UI design, and a comprehensive design system. Scope covered Jazz World (consumer super-app) and Jazz Business World flows across mobile and web self-care.

Approach

Built from research outward: understanding subscriber mental models for telecom tasks before designing UI. Established core journey patterns for recharge, balance, packages, and support, then systematized them into a scalable design system. Prototyped and tested flows on iOS and Android in parallel, with separate business-customer patterns for account hierarchy, billing, and management controls.

Key decisions

Design system first — investing in reusable patterns early so the product could grow without visual or interaction debt.
Consumer vs. business separation — distinct mental models for subscribers and business customers rather than one overloaded app.
Zero-to-one prioritization — shipping core self-care journeys before feature sprawl, based on research into daily subscriber tasks.
Cross-platform consistency — shared interaction language across mobile and web so support and marketing could scale.

What I learned

Telecom products win on clarity under stress—users often interact during outages, low balance, or payment failures.
A design system is not a deliverable at the end; it is how you survive scale.
Downloads are an outcome of daily utility, not launch marketing—repeat-use flows matter more than onboarding polish alone.

Key focus areas

User-centered design from zero — research, personas, journeys, and core telecom flows
Comprehensive design system and style guide for a scalable subscriber product
Wireframes, prototypes, and UI for iOS and Android consumer workflows
Business customer self-care patterns — account management, billing, and hierarchy controls on Jazz Business World

Outcome

Over 50 million app downloads and a 4.4 average user rating — demonstrating the impact of building a user-centered telecom experience from the ground up with a durable design system.
