Am an experienced MEAN stack developer, gained this experience from a startup whereby I single-handedly developed and maintained the web site. Using angularjs for smooth routing experience of users, mongodb to store the data and making the data available for the appplication as data is the most important factor in single page application. Because whatever you see and experience on front comes from database and goes through html templates and css styles. While you can alwats rely on single threaded node server handled by express for all the api calls to fetch data from mongodb. Have experience of deploying or Migratingthe same on aws in minutes on an ec2 instance. If you are a tech guy, then you already know by now how I am the best candidate. If not google mean stack and see how could summarize the entire core part in so few words and typing within 5 mins.
