  I had the opportunity to work with Neil, who was cooperative and understanding throughout the process. They maintained good communication and delivered the required work in a satisfactory manner.

  He did great in terms of coding and understanding the issues. It was a product finder bot. The product that was delivered was as promised. It was written in Python and Next.js. The only issue was the delivery time, but that was partially due to the embedding taking a while because of a large database. He clearly knows what he is doing, and you can easily communicate with him. He follows up and ensures everything works, which is nice.

  I'm very happy to have found this specialist. He built a RAG system for my project with great attention to detail and a clear understanding of the task. I plan to continue working with him to further develop and scale the system, and I hope for a reliable long-term collaboration.
