Senior AI Engineer – Healthcare Chatbot with Guardrails, RAG & Automation (Production-Level System)
We were facing key issues with our AI intake system, and Mubsher stepped in and handled them very professionally. He not only solved the problems but also proposed a much better approach than what our team initially had in mind.
He took full ownership, brought clarity to the architecture, and delivered a solid, well-structured solution. Highly reliable and easy to work with, would definitely hire again. Highly recommended.

Client Portal – Teams Communication Bridge (Prototype)
I had a very positive experience working with this developer. Communication was clear and consistent throughout the project, and they were responsive whenever clarification or adjustments were needed.
They demonstrated solid technical knowledge, especially around Azure, Bot Framework integration, and backend deployment. Even when we encountered configuration and authentication challenges, they remained proactive and solution-oriented until everything was properly aligned.
Overall, the collaboration went smoothly, deadlines were respected, and the final result met expectations. I would definitely recommend working with them again on similar projects.
