Leading the Cards Squad at SadaPay and contributing throughout the entire development lifecycle, from research to support, my responsibilities as a squad lead include:Use eXtreme Programming, including test-driven development, trunk-based development, and mobbing, to develop high-quality software.Collaborate closely with Product and Design in a cross-functional, vertical squad.Deliver measurable value for our customers and the business.Support the professional growth of other engineers.Outcomes achieved under my leadership:Achieved a remarkable 97% reduction in customer acquisition costs by strategically limiting free card orders to a targeted subset of customers, reduced decline transactions and offering open market fx rates. We developed BFF (Backend for front end) that dynamically adjusts fees and foreign exchange rates, enabling us to provide the most competitive rates to our customers and quickly respond to market fluctuations (such as differences between open market and interbank rates, and WHT changes). This innovation resulted in a 290% increase in FX revenue.Efficiently transitioned from a monolithic architecture to microservices, leading to a significant reduction in delivery time.Took on the challenge of ingesting and processing large volumes of data by constructing a robust data pipeline, facilitating the publication of Kafka messages, and enabling efficient storage—an impressive feat considering my background in frontend development.Designed and developed micro-frontends for iOS and Android platforms, contributing to the enhancement of modules within our domain.Streamlined the process of physical card ordering from synchronous to asynchronous, resulting in a notable decrease in failure rates, especially within the intricate flow involving three third-party vendors.Demonstrated leadership by mentoring a team of more than four engineers, fostering professional growth and knowledge transfer within the organization.

At Sadapay, our mission is to drive financial inclusion in Pakistan by simplifying financial services.I spearheaded the development of "SadaPay" from the ground up, utilizing Swift and adhering to the MVVM-FlowControllers design pattern while practicing Test-Driven Development (TDD).The architecture of SadaPay is multi-modular, leveraging CocoaPods for efficient dependency management. This design has empowered the establishment of over 10 squads at SadaPay, each with their dedicated repository. This segregation allows squads to develop and test their use cases independently, minimizing blockers and significantly reducing delivery time and bug occurrences.Ensuring the robustness of our codebase, SadaPay boasts over 90% unit test coverage, complemented by comprehensive UI testing for all user journey flows using XCTest and XCUItest frameworks.To maintain code quality and adherence to Swift conventions, SwiftLint and SonarCloud are integrated into our development pipeline. I personally set up the end-to-end CI/CD pipelines on Bitrise, ensuring seamless integration and delivery.The implementation of an Open API Client Code generator has been pivotal, automating the generation of our Swift client network layer from API specifications. This not only eliminates human error in API translation but also slashes development effort by 30-40%.Embarked on my full-stack journey by delving into backend development with Spring Boot using Kotlin, exploring microservice architecture, SQL databases, and gaining proficiency in Kafka.In fostering collaboration and swift feature delivery, I actively engage with the product and design teams, participating in regular Pair/Mob programming sessions to ensure alignment and a speedy development pace.

Careem is a ride-sharing app similar to Uber.Careem Pay is a unified, safe, and secure online payment system for Careem's services.We extracted CareemPAY from the monolithic Careem app and built a separate verticle. I am primarily responsible for the stability of the system using automated testing. We decoupled CareemPAY from the parent app as it was tightly coupled in legacy code. We removed singleton SDK initialization, which was a big task since many modules were dependent on it.We deprecated concrete type dependency injections and replaced them with abstract types, which helped increase test coverage. Additional Technologies used: Cucumberish, Gherkin, Kingfisher, Lottie-iOS, CI -> Bitrise, CD -> Firebase.Outcome:Reduce support tickets from 120 to less than 20 for a month. Significantly reduced crashes improving system stability. Increased unit test coverage from 0% to 60% and more than 90% of our modules are end to end UI tested.

ProjectHideboxAn innovative, quick and easy way to keep track of your possessions giving you the ease of having the information on you when you need it the most.I'm extremely pleased with how the project came out. I'm particularly proud of the app's animation, UI design, and easily-extended architecture (MVVM-Coordinators). Hidebox is built with Xcode and written entirely in Swift 5. It utilizes Auto Layout for UI design. Hidebox is my ongoing project.My RoleLead iOS developer and team lead for iOS and Android.
