I have been working at Ladybird Web Solutions since 2021. These are the topics I had better experience1. Oauth • I added oauth authentication feature in Php ews package which helps to connect Microsoft office 365 mailbox and fetch emails from mailbox to our application and create ticket. • Worked on passport application which supports oauth authentication mainly security purposes. This oauth authentication will provide access token and the client needs to pass this token whenever they using api. • I implemented passport client which helps to integrate third party application with our application. Like login with Google, Facebook etc.2. Payment gateway • Integrated Stripe, paypal and Billplz.3. Master/Slave nodes • Implemented one master and two slave nodes in Laravel application. In this case, I used aurora RDS. Whenever I write any data, it will write on master node. While reading, the data will fetch from read nodes. It will improve Better performance throughout application.4.Cache(File, database and Redis) • Cache will an important role in large datasets. Whenever you working on static data. You can use cache to stire data in server level5.Horizon • Recently integrated horizon queues in our application which helps to Monitor supervisor and queues in application level. We can use horizon whenever queue connection in redis. Unfortunately Laravel does bot support horizon for redis clusterLike event and listeners, Listener queue, custom commands, custom service provider and so on
