Natural AI Voice Call Optimisation

Worked with Zohaib again to refine the system and, as always, he delivered on time. Clear communication, quick with changes, and extremely persistent whenever we hit a roadblock—he stayed on it until everything was working exactly as needed. Great guy to work with. The only thing he still hasn’t figured out is when to stop working and get some sleep.

I worked alongside Zohaib on the Urdu/English voice-banking deployment for a first-tier Pakistani bank. He owned the voice agent end-to-end — the real-time pipeline, the RAG layer over the bank's knowledge base, and the integration work inside a closed network with no outbound access. That last part is where most engineers stall; he worked through the firewall and whitelisting process with the client's security team himself instead of escalating it. The system is in production handling heavy daily volume. He's steady on long-running enterprise work, which is a different skill from shipping fast.

I have worked alongside Zohaib at Fortanixor Technologies for almost an year now, and he is one of the most capable engineers I have worked with. His expertise covers machine learning, NLP, computer vision, model deployment, Generative AI, Dynamic RAG Pipelines; basically anything AI, and he approaches every problem with a clear, structured mindset. He doesn't just build models; he understands the business problem behind them and designs solutions that actually work in production. Beyond his technical skills, he is reliable, communicative, and easy to collaborate with. He meets deadlines, raises issues early instead of hiding them, and is always willing to help teammates. Any client would be lucky to have him on their project. I recommend him without hesitation.
