You will get ElevenLabs voice in your app — TTS, voice cloning, or realtime speech

Project details
ElevenLabs produces the most natural AI-generated speech available. I integrate it into web and mobile apps properly — streaming audio that starts playing immediately, voice cloning pipelines, real-time conversational speech, and audio player UI that doesn't fight the browser.
Audio integrations are trickier than they look. Streaming TTS requires careful buffer management. Real-time speech needs WebSocket handling and latency optimisation. Voice cloning requires a proper audio upload and processing pipeline. I've built all three for production apps and know where each breaks.
What I build:
• Text-to-speech with streaming audio playback
• Voice selection and voice settings UI (stability, similarity, style)
• Voice cloning pipeline (audio upload, clone, use in TTS)
• Real-time conversational speech (WebSocket-based, low latency)
• Audio player component (play/pause/progress/speed)
• ElevenLabs API cost management and character usage tracking
• Mobile audio support (React Native Expo AV or similar)

Flutter mobile build and ongoing upgrades
Sailesh is one of the best engineers i have ever worked with. He has deep skills across many software engineering practises. We could leave major technical decision making to him, as well as lean on him to lead the build and launch of multiple products.

Flutter Mobile App Debugging for App Store Submission
I've troubleshot my Flutter app for some weeks and there were a few different and unexpected bugs. Sailesh was an amazing support throughout this process because he always knew how to solve these niche issues in a matter of hours. It's been a pleasure working with him and I appreciate the communication and relationship established along the way.

iOS - UI Unresponsiveness Error
Trust is very important when working with someone from Upwork and I am very happy for the relationship I have with Sailesh. For this project, he provided assistance beyond the scope and assisted in providing alternative solutions. Always a pleasure working together

Sailesh was a great! He helped us fix some issues with our Android App. From the moment we started chatting I knew he would be good. He was able to understand instructions clearly and provide critical feedback. He was quick in his work and ongoing communication was excellent. Completed the job 100% successfully. Would highly recommend.

Dhulikhel, Nepal - 10:56 pm local time
I've been the sole mobile/full-stack engineer on products that went from nothing to real users — React Native, Flutter, Expo, Vite, Express, Hono, MongoDB, PostgreSQL — so you're not waiting on five different people to ship one thing.
WHAT I'VE BUILT
→ OneTake — mobile lead for a year. Every pivot, every weekend bug, handled.
→ Solas Compliance — policy-to-rules compliance review for finance and iGaming, with a full audit trail back to source clauses
→ Rayu — an AI nutritionist paired with a wearable, grounded in live health data
→ Palete, Sambad — AI agents running customer operations over WhatsApp and omnichannel inbox
→ Sajilo Sewa — Nepal's home-services marketplace, 50+ services
→ Flexera — connected fitness hardware + app
AI WORK
→ RAG pipelines, eval suites that gate deploys, cost/latency budgets
→ Agents and internal workflows with typed tools, permissions, audit trails
→ OpenAI, Gemini, Claude API integration — production use, not demos
→ Claude Code, Codex — daily use
STACK
→ Mobile: React Native, Expo, Flutter, Dart
→ Web: React, Vite, TypeScript
→ Backend: Express, Hono, Node.js
→ Database: MongoDB, PostgreSQL
→ Cloud: Firebase, AWS, GCP
I reply within 12 hours. Scope is clear? I can usually start the same day.
Drop me a message — glad to take a look at what you're building.
