Olga Convey, SVP Software at RMS
FJ exhibits extreme bias for action, while developing innovative and relevant solutions with minimal guidance. He truly understands customer needs, dives deep to analyze target application and edge cases, and delivers beyond expectations. While developing reference applications for the new wearable platform, FJ provided both client side and core components that made the platform easy to use and position as a core building block. FJ is a great simplifier and a key contributor to any project.

Miril Chheda, Senior Software Developer at Netflix
To describe FJ in two words , he is a “Go Getter” . No matter the problem in front of him, FJ will always find the solution. His resilience is unmatched . I had the privilege to work with FJ while at Intel. He is a skilled iOS developer who is always able to deliver on time no matter the time zone he is currently in. Along with technical skills I also valued FJs meaningful UI insights. He understands a product inside out and always strive to make it perfect to the best of his ability. He is destined for great things and would be an invaluable addition to any team. I am grateful to have worked with him and hope our paths cross again in the future.

Gabriel Cartier, CTO at Samsao
FJ is a smart software developer and was a great asset to our team on the projects he worked on. He is capable of building complex applications and uses librairies, patterns and everything that a senior software engineer should use. FJ is always on the edge with the latest trends, librairies and technologies, I would recommend him to anyone in need of a senior software developer.

Awane Jones, CEO at Merchlar
