Hi,
We are 7+ years experienced developers and created various web apps and mobile apps. You can just check our portfolio for the products/apps that we built.
We are already experienced with multi-user authentication system with type of following:
1. Core laravel Auth
2. JWT Auth Tokens
3. OAuth
4. BShaffer Auth
5. Auth with Basic header
I have worked on a system where we have done authentication with all these in one and with multiple user types. so we are already experienced with it. And about our laravel experience, you can check our portfolio and even our open source projects.
We have worked with various startups and growing companies to make some really great products. We understand business requirements very well to make a best solution which is required. so when you need more than just a programmer who can put his own inputs on table to make a product better, we can be the best choice.
We are also pretty much contributor in laravel. You will also find one open source project of laravel on my portfolio named "Laravel Generator".
We are familiar with multiple other technologies like Laravel, AngularJS, Bootstrap, iOS, Android, NodeJS. MongoDB, MySQL, Elastic Search, Redis etc. We know how to make a best mixture of technologies and build the best solution.
I think this is a best opportunity for both of us to work together as a long term.
Hope to hear you soon.
