As the requirement demand, i have experience in MEAN stack framework.
Currently i have done 2 projects in mean stack as a full stack developer.
A charity crowd funding and tak manager application.
In both i have worked with angular 3&7, node js, Express and mongo db.
In angular i have worked in firebase, modular, form elements, date elements, http api access, bean access, validation, service class usage, errors, routing, etc
In node using express js, i have accessed mongo db and sent errors to front end and created rest api.
Will capture db errors and user defined errors and sent to front end.
I definitely will meet your requirements and will deliver more than your expectation.
I work in a very professional way, i will create technical documents like db structure, TLD so that in future you can scale the project with anyone without any issue
Looking forward to work with you.
Thank you.
