Hi,
As from the short description of the project, i can see you want a mobile app, cross platform, with inventory and map/GPS capability.
I can work on this project and we can work on technology like react native to make it cross platform from single code base. For backend we can choose NodeJS or asp.net core.
I have 5+ years experience in web application development. I have mostly worked with Asp.net Core, Asp.net MVC 5, Web API, MS SQL Server, including frontend and backend both parts. I have done many third party integrations like TransUnion, Google Maps, Stripe Payments, Velocify, RigCentral etc. From last two years i am working on projects using AngularJS, Angular 4+ and React based front end technologies with backend technology as asp.net core API and NodeJS.
Please let me know more about this project in chat.
Thanks,
Siddharth S Mishra
