Tawk.to provides customer relationship management (CRM) solutions and services to website owners. I have been working on their iOS application since joining the organization. This app enables agents to monitor, chat with, and speak with clients/visitors on their website. It also offers ticket creation, management, and issue tracking for websites. I worked on several features, including syncing property lists with the back end and writing custom Core Data migrations for the new property models. I also contributed to other parts of the codebase by refactoring, writing test cases, and fixing a couple of issues.

CommChat is an end-to-end encrypted chat application. It allows users to send secure instant text and voice messages, makes voice and video calls, and share images, documents, and other content. I worked as one of the key developers in this application. I developed the storage layer with the Couchbase Lite database. I implemented the networking layer for REST APIs consumption and file uploading/downloading to and from the server and message transmission protocols. I developed screen-sharing, and iCloud backup restore features. I also contributed to some parts of the call feature.

ShareTrip helps users plan and manage their travels effortlessly. It allows users to search, browse and book flights, hotels, and travel packages. I developed the hotel and flight features for this app.

SmartThings allows users to connect and control Samsung's smart devices quickly and easily. Users can monitor and control smart devices, home appliances such as TV, refrigerator, speakers, robot vacuum cleaner, and many more. I mostly worked on the UI part of the application and developed the settings page and several reusable UI components.

uVited is an online eCommerce website focusing primarily on natural and organic health care products. I developed a couple of REST endpoints for their internal mobile application. These endpoints facilitate delivery persons to update order status on the go.
