Professional Experience
Intermediate Backend Developer, talkSay
11/2022
Talksay is a mobile app that allows users to discover and connect with friends and host live audio rooms in their
preferred language. The app uses a data-free approach to provide seamless communication to its users.
Backend developer at TalkSay and was responsible for overseeing the development of the app's backend
infrastructure.
The app's backend is designed around a functional API that works seamlessly with multiple databases,
including PostgreSQL and MongoDB.
The backend team at Talksay has created audio rooms using Media-soup v3, a NodeJS-based framework that
provides real-time communication capabilities to the app's users.
The app uses Firebase Cloud Messaging to deliver push notifications to its mobile users.
To establish real-time communication between clients and the API, the app uses WebSockets. This technology
enables seamless communication between the client and the server without the need for frequent API calls.
Implemented all API functionalities on the backend, including user authentication, audio room creation, and
virtual gift exchange.
The app uses external APIs and services to enhance its functionalities, such as users' OTP and withdrawal
services.
To enable users to send virtual gifts to each other during audio room sessions, we implemented a virtual gift
system within the app's backend infrastructure.
To enable in-app purchases for the mobile app, the backend developer has implemented Google and iOS inapp purchase SDKs.
Carried out bug fixes, user testing, and end-to-end testing to ensure that the app is reliable and free from
glitches.
Created documentation for the various services used within the app's API infrastructure to ensure smooth
collaboration between the development team members.
