    Nothing could be better, really great job in understanding the requirments and getting the job done on time. Had a very pleasant experience working. A true professional in the field. I had very urgent deadline and with very minimum information from me, He delivered it within the time constraints . This was a tough GNN model update and it was done perfectly. His level of expertise and execution is well beyond what you are paying for. I would highly suggest many times over.I am looking forward to working with him again, thanks Waruna!

    My experience with Waruna was great! He was able to comprehend the complex neural network design that I had envisioned and created a visual representation as discussed in our scope of work. His skills in this niche are quite exceptional, especially considering he hasn’t finished his degree yet! I can only imagine better things to come and I would definitely recommend him and the future
