We are developing the fully integrated system for vessel companies, it consists of a HeadQuarter (onshore) server, Vessel Servers, and an iPad application.
You can find and test it in AppStore: BL4SEA.
BL4SEA is an online and remote service for inspections and surveys onboard all kinds of vessels and units. Using iPad offline app allows vessel crew to handle inspections while in the sea and later sync with the server through a satellite channel, with guaranteed delivery service.
Inside a system there is a custom survey engine we developed, which allows HQ Users to set up inspections as a set of Pages and Questions of different type (Text, Number, Date, Freeform, GPS Coordinates, Taking pictures with iPads, etc). A robust workflow engine we developed is used for remote inspection results verification by the auditors, who are located onshore.
Headquarter Admin Section: ASP.NET MVC, Kendo UI MVC, SQLServer 2014, MongoDb, EntityFramework(CodeFirst), Ninject, AutoMapper, DocX and PDF Rendering. Mobile app for iPad: Xamarin iOS, C#, JSON, MVVMCross, MsgPack, PCLCrypto.
