Featured case study
elGrocer Grocery
Flagship production Android platform: scale, revenue, and architecture ownership over six years.
UAE grocery delivery needed a shopper app that could handle real-time ordering, payments, maps, and notifications as daily orders and store coverage grew. The mobile platform had to stay stable while the business scaled toward acquisition.
Responsibilities
- Lead Android ownership for six years on the flagship shopper app
- Own architecture, releases, performance, and production incident response
- Partner with product, backend, and operations on roadmap and delivery
- Guide modularization, Compose adoption, and platform quality standards
- Support team growth and technical decisions through the e& acquisition
Technical challenges
- Scaling order volume and concurrent users without degrading checkout or maps
- Keeping payment and wallet flows reliable under peak demand
- Maintaining notification and real-time sync as feature surface area grew
- Migrating a large codebase to Jetpack Compose and modular boundaries safely
Architecture decisions
- Modular Android architecture to isolate payments, catalog, maps, and account flows
- Jetpack Compose rollout for high-traffic screens with backward-compatible migration
- Firebase and REST integrations aligned with backend scaling and observability
- Kotlin Multiplatform initiative to reduce duplication while preserving Android quality
Scaling efforts
- Daily orders grew from about 100 to over 2,000 during long-term ownership
- Monthly active users expanded from 2,000 to 150,000 on the shopper app
- Release cadence and performance tuning kept pace with regional store rollout
- Platform stability held as the product became core to elGrocer's growth narrative
Results
- Contributed to roughly 10× revenue growth and a larger average basket over years of ownership
- Helped the mobile platform become a strategic asset in acquisition by e& (Etisalat Group)
- Bravo Award for leadership, collaboration, and team impact
- Startup equity granted twice for long-term technical and strategic contribution
