Real-Time Voice PHP/WebRTC Workflow Platform Development
Budget: $250 – $750 USD
Senior PHP + WebRTC Engineer Needed for Real-Time Voice Workflow Platform
We’re looking for a highly experienced PHP/WebRTC developer to help expand a multilingual real-time communication platform used in operational environments.
This project focuses on improving voice-driven workflow efficiency for mobile teams through lightweight speech accessibility features layered into an existing Push-to-Talk (PTT) infrastructure.
Please read carefully before applying:
This is NOT an AI assistant project
This is NOT a chatbot or autonomous agent system
This is NOT an always-listening voice platform
The goal is practical operational usability:
voice dictation instead of typing
audio playback instead of reading
multilingual communication support
fast mobile-first interaction
Current Stack & Environment
PHP backend architecture
Existing WebRTC/PTT infrastructure
Existing async transcription pipeline
Provider abstraction layer already implemented
Mobile-first thin-wrapper application architecture
We need someone comfortable working inside an established architecture without overengineering or replacing core systems.
Scope of Work
Phase 1 - Speech-to-Text Accessibility Layer
Implement lightweight dictation support across operational text areas including:
task notes
comments
service requests
chat inputs
operational forms
transcript assistance
Requirements:
tap-to-speak or hold-to-record UX
asynchronous processing
mobile/tablet optimized
editable transcript preview before submission
graceful failure handling
provider-agnostic implementation
Phase 2 - Text-to-Speech Playback
Add operational narration support for:
instructions
agenda items
translated content
notes/comments
operational communications
Requirements:
one-tap playback
pause/stop controls
visible playback state
multilingual playback compatibility
lightweight execution with minimal workflow interruption
Important Technical Constraints
You MUST:
work within existing provider abstraction architecture
avoid vendor lock-in
maintain async/non-blocking behavior
preserve responsiveness of core PTT workflows
support mobile wrapper permission handling
ensure no tenant data leakage
You MUST NOT introduce:
conversational AI
autonomous workflow logic
wake-word systems
always-on listening
floating assistants
employee monitoring/scoring
complex voice-command engines
Ideal Candidate
We’re specifically looking for someone with strong experience in:
PHP backend systems
WebRTC and real-time communication
mobile-first architecture
async processing
speech/transcription integrations
scalable multi-tenant systems
operational SaaS products
Bonus if you’ve worked on:
hospitality systems
workforce communication tools
multilingual communication platforms
accessibility-focused UX
Deliverables
Successful completion includes:
functional speech dictation
functional narration playback
mobile/tablet validation
graceful failure handling
provider abstraction compliance
non-blocking workflow verification
To Apply
Please include:
Relevant PHP/WebRTC projects
Experience with speech APIs or transcription systems
Mobile wrapper/native container experience
Architecture examples involving async workflows
Availability and preferred hourly rate
We’re looking for a senior engineer who can move fast, communicate clearly, and respect existing system architecture.
