  Collaborated closely with the product team to collect requirements and assisted the development team in completing their tasks. • Efficiently migrated functionalities to core modules, streamlining the process with modules that have a single responsibility and are easy for developers to use. • Successfully led the iOS development of an important project named Super App, which utilized a Server Driven UI approach to control the front-end through the back-end. • Addressed the problem of code conflicts in a team of around 25 iOS developers working on the same project in a single repository by creating a script using XcodeGen to generate the project file with a YML file, which resulted in an 80% reduction in conflicts during branch merges.

• Chapter Lead Engineer · Kavak05-01-2021 – 07-01-2022

  Created a new architecture plan using Clean Architecture and MVVM, resulting in a more robust and testable app that decreased crashes and increased customer satisfaction. • Proposed and implemented a plan to modularize the app, utilizing Cocoa Pods as the Package Manager. • Migrated the app's back-end requests from REST to GraphQL using Meta's recommended implementation, which was subsequently adopted by the entire development team. • Proposed and created a POC for implementing the framework Combine in the app, resulting in a less code solution for two-way binding between the views and the model.

• Software Engineer · Kavak08-01-2019 – 05-01-2021

  Collaborated closely with the product team to gather requirements and ensure timely delivery of features within scope. • Implemented the MVVM pattern for the app which originally used only MVC, transferring the business logic from the view to a view model object. • Focused on bug fixing and improving application performance, resulting in a 99.89% crash-free rate as indicated by Crashlytics.

• Sr Software Engineer · Pinterest08-01-2023

  • Led a team of engineers in a pivotal project at Pinterest, implementing Surveys within the Search feed to enhance Pin Relevance and collect valuable user preferences data. • Spearheaded the development of a data-gathering project aimed at profiling user interests and cataloging relevant shopping items, contributing to an enriched user experience and targeted content delivery. • Worked on the migration of team modules from Objective-C to Swift, ensuring a smooth transition and leveraging the latest advancements in iOS development for improved efficiency and maintainability.
