Design and Development of the Hello Engineer Android and Web-Based Construction Consultation Application

Information from the abstract

Access to qualified construction experts is often constrained by location, scheduling, and fragmented service channels. This study designed and developed Hello Engineer, an integrated construction-consultation platform consisting of a web-based administrative application and two Android client applications for clients and consultants. The system supports consultant registration and verification, expertise-based discovery, chat consultation, appointment scheduling, laboratory-test ordering, location-based services, ratings, and payment processing. Development followed the Dynamic Systems Development Method because the project required iterative prototyping, continuous product-owner involvement, and priority-based adjustment of features within fixed time and resource constraints. Functional black-box testing covered nine scenarios across authentication, account management, consultant selection, appointment booking, chat consultation, laboratory-test ordering, and logout. All nine scenarios passed, producing a functional-test success rate of 100%. The result demonstrates the technical feasibility of integrating previously fragmented construction advisory services in one role-based mobile and web architecture. The evaluation is limited to functional verification; standardized user-based usability, performance, security, and scalability tests remain necessary before production deployment.
