ABOUT ME
Senior Full-Stack Developer ( Java / ReactJs / Android )
Senior Full-Stack Developer ( Java / ReactJs / Android )
20+ years in IT development on object oriented technologies ( Java , .NET and web technologies ) ,from small to blue chip companies,as consultant.I also successfully experience the digital nomad experience with 5 stars rating an 6400 hours on the upwork platform.
My vocation started very young , at the age of 14 years old so i have been trough quite a few different time area of computer science.
While i used to be focused on coding , i now have a growing desire about knowledge transfert.
I am still quite busy on the coding side but teaching strategies and workshops are something i am curious about. So besides a one to one assistance on the code , feel free to ask about a workshop ( ie. i would like to know about ORM , or multithreading ) Choose a time frame ( i.e. i would like it to last 1,2, or 3 hours ) and i can handcraft a workshop so that we efficiently spend your budget , leaving asides issues like environement setups for a more streamlined experience.
Offline chat is free so feel free to send a message to enquire. If i am available i will be happy to reply.
I am also available for freelancer activity , please contact me to discuss further about the project scope. That is a different workflow.
I appreciate you took the time to read my profile.

He has a wealth of experience and was able to zoom out on my project and point out flaws in my design and approach that led me to the technical problems I was having https://xyproblem.info/ ! Where most focus on the solution they believe is best as fast as possible, Perez tried to deeply understand the problem first. Highly recommended.

Philippe knows his stuff about database architecture and was able to help me fill the knowledge gaps that I had prior to speaking with him. He was able to identify what I wasn't understanding and explained things in ways that were easy for me to grasp. If you're reading this review because you're thinking about hiring him, I can tell you that I do NOT regret working with him.
