Worked on MyZesty media editing native app to improve the code design and fix several issues. Worked with SwiftUI, Combine, MVVM, Metal framework, AVFoundation, etc. Collaborated with designers to clarify designs and suggest improvements. Worked with the lead and fellow developers to plan tasks and share updates in daily and weekly meetings: reviewed PRs, tested features, prioritized tasks, and managed deadlines.Accomplishments @ Beyond Apps Group:● Implemented three major updates:● Improved video seek implementation by using operation queue for fast seek● Introduced MVVM structure for MainScreen, TimelineArea and some othermajor View classes● Changed the Metal TextureProvider seek and play functions to fix the criticalwrong frames issue, changed the play behavior to use common serialdispatch queue for playing and as underlying queue for seek operation queue.● Debugged several critical issues, and fixed their root cause.● Fixed several major functionality bugs like app hangs on AVFoundation corefunction and fixed several UI issues.● Fixed video seek slowness due to incorrect manual offset updates in the three linked UIScrollViews.● Implemented the syncing of three UIScrollViews with the player view using the Combine framework.● Helped other developers find root cause of bugs● Self reported tens of issues to QA team● Discussed UI/UX related queries with the design and product team.

Conducting technical interviews that include project discussions and knowledge/coding questions. The knowledge questions are tailored specifically to the job and cover data structures, algorithms, and mobile technologies. Coding sessions are mostly 45 minutes long in a pair programming style. Afterward, full reports are written that cover overall performance, detailed responses to knowledge/coding sessions, coding style, and communication.

Developed core features of the Tawk.to application using SwiftUI, Combine, CoreData, and scalable design patterns like MVVM, repository, and dependency injection. Tawk.to is a live chat software that helps businesses communicate with and deliver customer support to clients and website visitors. Collaborating with designers to clarify designs and suggest improvements. Worked with the lead and fellow developers to plan tasks and share updates in daily and weekly meetings. Reviewed PRs, tested features, prioritized tasks, and managed deadlines.Accomplishments:- Built several features with the MVVM pattern, including Active Chats and the Live Visitors feature- Built the Direct Messaging feature using protocols and repositories for abstraction to networking and Core Data- Built the Property Selector component using MVVM, which is used in the Monitoring, Inbox, and Home features and supports separate configurations for each- Built generic ItemsPicker and AgentsPicker using protocols, allowing new items to be shown in the list simply by complying with some protocols- Built custom UI views based on Figma designs, including buttons, alerts, and texts fields
