I’m building a custom Android application whose entire business logic will flow through remote APIs, and I need someone who can own both sides of that interaction. On the mobile front, you’ll craft a clean, responsive Android app (Java ) that consumes the endpoints I provide. On the tooling front, I rely on POSTMAN for every stage of the back-end integration, so your day-to-day will include importing the collection, refining environments, and, most importantly, running the automated test suites inside Postman to make sure each call performs exactly as expected. The scope is straightforward: create the app screens, hook them up to the API, then validate the whole flow by executing and, where needed, extending my existing Postman tests. If you’re comfortable living in both Android Studio and Postman, we should be a great fit.
