Unify a Logistics Driver App and Add Bluetooth Vehicle Telematics
Overview
What this challenge is about.
Unify a Logistics Driver App and Add Bluetooth Vehicle Telematics. Advanced challenge in code. Writing production code that solves real engineering problems,...
The Brief
What you'll do, and what you'll demonstrate.
Decide whether one React Native app with Bluetooth On-Board Diagnostics telematics can reliably replace Meridian's three legacy driver apps, and prove it through a ten-driver, two-week pilot.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Consolidate fragmented mobile workflows into one coherent React Native application without losing any existing capability
- Integrate Bluetooth Low Energy telematics from a generic On-Board Diagnostics adapter, handling pairing, reconnection, and operating-system background limits
- Decode raw diagnostic responses into meaningful signals and detect events such as harsh braking from noisy sensor data
- Design offline-first sync that survives multi-hour connectivity gaps with no data loss
- Run a structured field pilot and translate measured results into a defensible operational recommendation

Careers
Career paths this challenge builds toward
Completing this challenge demonstrates skills that transfer directly to these roles:
Mobile Engineer
Consolidating three production workflows into one resilient React Native app mirrors the core mobile-engineering job: shipping a cross-platform application that holds up in the field, not just in the simulator, while preserving every capability users already depend on.

Connected Vehicle / IoT Mobile Engineer
Reading live diagnostics over Bluetooth Low Energy from vehicle hardware and turning noisy signals into reliable events is exactly the work of connected-vehicle and Internet-of-Things mobile teams, who must reconcile flaky wireless links with strict data-completeness expectations.

Field Reliability Engineer
Designing offline-first sync and proving it through a measured pilot bridges to field reliability roles, where the deliverable is evidence that a system survives real-world connectivity gaps and a clear recommendation that operations leaders can act on.
