Senior Software Engineer II · Leading engineers on the mobile team · 2015–present · Ongoing
Growing with the products and the teams
I joined Nana in 2015 and helped build its customer application during the early stages. As the products grew, my work expanded into warehouse, delivery, and business applications, followed by engineering leadership and new systems and tools.
I also developed Nana’s AI customer-service agent for conversations and support ticket handling. It is available within Nana’s app and through a web browser. The system supports text and voice conversations and is used by the support team in production.
Evolving established products while people continue to depend on them. This requires understanding the existing codebase, team workflows, system integrations, and the effect of each change on users.
My responsibility
I contribute to implementation and technical decisions, lead engineers, and onboard new team members.
My responsibility varies by project, from developing part of a team-owned product to building a complete application or system within the company.
I modernize established applications and support testing, releases, and production troubleshooting.
Engineering decisions
I choose approaches around the product, its existing codebase, and its integration needs. My work includes Kotlin and Java for Android, Flutter applications, React Native modernization, and service and AI integrations using Python and JavaScript.
These are selected examples of my work at Nana. Each record identifies my contribution: some work was delivered within a team, while other applications and systems were built independently within the company. The page includes both public applications and internal systems.
AI Customer Service Agent
Live in production · used daily
Developed Nana’s AI customer-service agent.
I developed Nana’s AI customer-service agent for conversations and support ticket handling. It serves Nana and Rasseed, and the support team uses it in production.
The challenge
Bring Arabic and English customer conversations and support-ticket handling together through an AI agent available within Nana’s app and on the web.
What I built
Developed the agent’s conversation experience in Arabic and English.
Connected the conversation experience to existing support-ticket services.
What this work demonstrates: Developing an AI customer-service agent for real support workflows.
Engineering decisions
I used JavaScript to develop the conversation experience and connect it to existing support services. A colleague developed the ticketing backend.

Contributed across the application’s early build and later development phases.
I helped build the application during Nana’s early stages and returned across later phases to develop features and support releases.
The challenge
Evolve a customer app over many product phases while protecting critical ordering journeys and production health.
What I built
Helped build the customer application during the early product stages.
Developed features and supported releases across later phases.
During the final stage of my direct involvement, monitored stability, investigated production issues, and helped maintain critical ordering journeys.
What this work demonstrates: Developing and supporting a long-running product across multiple stages.
Engineering decisions
Native Android, Java, and Kotlin matched the mature codebase; Firebase and Crashlytics supported release visibility and production diagnosis.

Responsible for development and maintenance through much of my time at Nana.
The application supports order fulfillment and delivery teams across orders, barcode scanning, location, payments, and work metrics.
The challenge
Modernize a decade-old field application while keeping order fulfillment, location, payments, scanning, and release continuity working.
What I built
Led the incremental migration from Java to Kotlin and modernized the architecture.
Developed integrations and local storage with versioned database migrations.
Added unit and instrumentation tests with JUnit and Espresso.
Led and onboarded engineers joining the team.
What this work demonstrates: Sustained responsibility for a complex application, combining development, modernization, testing, and engineering leadership.
Engineering decisions
An incremental Java-to-Kotlin migration reduced rewrite risk; MVVM, Hilt, Room, Retrofit, Firebase, and targeted Compose adoption improved testability and maintainability.

Contributed to and modernized a team-owned application.
Nana’s business application supports purchasing workflows and live auctions.
The challenge
Modernize a team-owned B2B application without destabilizing an established product, while delivering a responsive live-auction journey through an external service.
What I built
Built a live-auction experience integrated with an external service.
Implemented upcoming lots, bid updates, and bid placement.
Supported dependency upgrades and codebase maintainability.
What this work demonstrates: Adding new capabilities to an established, team-owned product.
Engineering decisions
React Native was the existing platform choice, so the work combined responsible upgrades with a third-party auction-service integration for upcoming lots, real-time bidding state, and bid placement.
