Simon is a dream consultant, he can interpret product vision into actual product roadmap, plan, technical architecture and finally manage the execution to build the product. We worked w/ Simon for almost a year on an AI / machine learning project and he became a trusted part of our team. I highly recommend Simon and his team, happy to be a reference anytime. - Juefeng Ge, CMO/CPO @ Ylopo

Simon is definitely a rare find. I don't think I've ever encountered anyone as good as he is. He's definitely CTO material and his background from working at companies like Amazon definitely has given him experience in building complex, scalable applications. He not only thinks about implementation details from an engineering point of view, but also always helps evaluate the practicality of the solution from a product side. He and his team did an excellent job and we are honored to have worked with them for our project. - Ricky Ho, CEO @ Treelab

Neco has been my go-to guy as we needed complicated features developed on a tight deadline for a new business opportunity. He has been flexible and able to catch the ball and run with it even when I don't have time to provide detailed specs. Neco built a product for us from the ground up using state-of-the-art technology, and was also highly capable in moving a legacy project forward and making important architectural improvements even in a framework that he was initially less familiar with. It's always a pleasure to work with Neco and I'm grateful to have had the opportunity to do so! - Nathan Keyes, CTO @ InitialView

Osman is an amazing full stack developer. He is very detailed oriented and implements solutions both quickly and effectively. I think he's probably one of the most senior developers our team has ever had the honor of working with. I'm confident that he can be a tech lead for almost any project no matter its complexity as he's quick to pick up any new stack and is able to evaluate different solutions from both a product and engineering standpoint. I highly recommend him to anyone who needs someone to take lead and develop amazing, scalable web applications. - Derek Chan, CTO @ Treelab

Osman is a very talented architect and BE. He has led the development of our MVP and delivered his part within proposed billable hours. He is highly responsible. To help us to keep to schedule, he resumed his work immediately after he was recovered from COVID. I'm very grateful for having Osman in this project and would highly recommend him for any startup team. - Eric Zhang, CTO @ ClassAIR

Simon and his team at Xanthous Tech have raised the bar for a development firm. They consistently deliver incredible results and at lightning speeds. They're also a joy to work with. Unlike other development firms, you have complete transparency into their process, and can see every code commit and track every minute. They have deep experience with Serverless framework, React, Next.JS, GatsbyJS, APIs and Modern DevOps that I haven't found anywhere else. I've almost wanted to keep them a secret because they're that good. You can stop looking for developers, Xanthous is the best you'll find anywhere. - Zack Franklin, CEO @ AMZKungFu

Simon and his team are the most professional I've worked with. Their professionalism and commitment to our contract helped us retain clients and revenue. They were flexible when we needed it, and they truly became part of our team. Probably the best Upwork experience that we've had so far. - Lou Rabon, CEO @ Cyber Defense Group
