What does an Agora.io developer do?
An agora.io developer builds real-time communication features into web and mobile applications using Agora’s software development kits and application programming interfaces. This specialist codes the logic that allows users to join voice or video channels, publish their own media streams, and subscribe to streams from other participants. The work focuses on integrating specific Agora tools to create stable, low-latency audio and video experiences without building the underlying network infrastructure from scratch.
- Integrate the Agora Web SDK into a front-end application by installing the package via npm or loading it through a content delivery network. Write code that initializes the client, creates local audio and video streams, and manages the user interface for displaying remote participants. Handle events such as stream subscription, playback errors, and device permissions to ensure the call interface behaves predictably for end users.
- Implement secure access controls by setting up token generation flows for real-time communication, real-time messaging, and chat services. Connect backend services to Agora’s authentication endpoints to produce time-limited tokens that validate user identity before they join a channel. This step prevents unauthorized access to live sessions and protects the integrity of the communication network.
- Extend core calling capabilities by configuring server-side REST APIs for advanced features like cloud recording and real-time transcription. Write scripts that trigger recording sessions when a call starts and stop them when the session ends, saving the output to designated storage. Use these APIs to manage real-time transcription controls or integrate with RTMP services for live streaming to external platforms.
How to hire an Agora.io developer on Upwork
Step 1: Post a job
Define your real-time communication needs clearly to attract qualified candidates. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description in seconds. Describe your requirements in a few sentences, and Uma constructs a tailored post for this role. You can write a new post, update a saved draft, or reuse an existing post.
- Specify whether you need WebRTC-based calls, token generation flows, or REST API integrations for cloud recording.
- List required SDK experience, such as implementing the Agora Web SDK via npm or CDN for front-end apps.
- Clarify if the project involves managing local and remote stream playback UI or handling SDK errors.
Step 2: Evaluate candidates
Look for proof of working video-call features that join channels and publish media streams. Uma runs instant video interviews and builds shortlists with side-by-side comparisons to speed up your review.
- Check for code samples showing client initialization, channel joining, and stream subscription logic.
- Verify experience generating access tokens for RTC, RTM, or Chat access to authenticate sessions securely.
- Review past work integrating server-side APIs for extensions like real-time transcription or RTMP streaming.
Step 3: Interview your top choices
Discuss technical approaches to latency management and stream quality during live sessions. Schedule and conduct interviews within Upwork Messages, which generates an immediate transcript and summary after each one.
- Ask how they handle view creation and removal for remote users to maintain a clean call interface.
- Question their strategy for debugging SDK errors when publishing local streams fails.
- Explore their method for securing token generation endpoints to prevent unauthorized network access.
Step 4: Agree on scope and begin work
Set clear milestones for delivering functional call features and backend integrations. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.
- Define deliverables such as a working video-call feature that renders subscribed remote streams correctly.
- Agree on integration code standards for front-end SDK setup and call UI behavior.
- Confirm backend tasks, including token-generation integration for authenticated RTC sessions.
