Hello, I'm an agile Back and FrontEnd developper who worked on large scale projects. I can advise you the good technological and architectural choices early on so you save time. I'm precise and can figure problems out quickly. I love to have a deep understanding of the tools I use. I also enjoy writing simple, clean, efficient, maintainable and re-usable code. I wrote several AngularJS apps and designed REST API's. When I design a new service, I keep qualities like scalability, performance, responsiveness, user-experience, and SEO in mind. I love to streamline workflows with tools like Grunt, Git and PM2 to deploy new releases several times a day, making use of best practices and setting up both Unit and End to End tests. I also have skills in system administration, and can setup a server, different environments, databases, email servers, certificates and so on. In the past, I used to work with Php, JQuery and MySQL.

I will help you refactor controller code in a nice shared service, where it should be. We can also create a service from scratch together.

I will help you implement ui-bootstrap or any other angular library's directives in your project. Also I will give you explanations about what I do and answer your questions add the script tags, wire it all together with a scope and make your data available to the directive, and finally customize and use the directive as you would like!

I will help you build functions that make use of the power of asynchronous modern javascript. promises and callback based functions will have no more secrets for you. learn how to intercept errors even in deep function "nesting" do local and global error handling to make your users happy and build services that dont break randomly. The async library for nodejs or the $q for angularjs will be your friends.

I would love to teach you master lodash/underscore javascript toolbelts as they are very powerful to make concise code. I will make up the examples or we will apply these amazing tools in your app.

Awesome mentor!
Pretty good
Could've been better
Needs improvement

Outstanding knowledge of Node and Angular. Was able to quickly understand the problem and showed me exactly how to fix it. Then took time to explain things to me. Would highly recommend.
Jennifer Oct 04, 2016

Romain is very professional. He creates an honest and friendly environment where you can feel relaxed. He is patient and persistent when it comes to dealing with the problem. He thinks logically, works methodically and comes up with creative solutions! He would also pause the session if he needs to look up something, which I though was quite sincere and honorable. I am glad I got serviced by him and would definitely seek his help again, if I have other issues. Thank you Romain!

Romain was fantastic. He helped me solve a Mongoose problem that had been nagging me for too long to admit, and he was friendly, methodical, and collaborative.
