Frequently asked questions

Can voice AI work on noisy audio?

Yes, with the right engineering. QuickComm reaches 94%+ transcription accuracy on compressed, push-to-talk hotel radio by preprocessing the audio and running two speech engines.

How fast can a voice agent respond?

My voice agents complete the speech-to-reply round trip in under 800ms using streaming at every stage.

How much does it cost to hire you as a voice ai developer?

Every project is scoped on a free 30-minute call. Because I work remotely from Islamabad, you get senior, award-winning experience at rates well below US and UK senior market rates, and the prototype phase is quoted at a fixed price so your risk is capped.

Do you work with clients in the US, UK and UAE?

Yes. I have shipped for clients in UAE, UK, Australia and Pakistan, and work remotely with overlap for UAE, UK, EU and US East Coast hours.

Do you write the code yourself?

Yes. I architect the system and write the critical code myself. For larger builds I also lead engineers from my team at Quickgen Technologies, where I am Co-Founder & CTO.
