My role

Sole backend engineer and mobile developer

DealerFlow mobile feed showing newly published wholesale inventory.

Problem

Wholesale vehicle buyers and sellers lose time when fresh inventory, offer status, and lifecycle changes are spread across slow manual workflows.

What was built

Built as a production-lean mobile system with a NestJS API, BullMQ-backed worker processing, persisted notifications, and lifecycle-safe inventory transitions. Buyers get scored matches and alerts, while sellers manage inventory, offers, and inbound inquiries from a mobile workflow.

Result

Beta pilot with working mobile workflows for buyer matching, seller inventory management, and real-time notification delivery

How the system was structured

This section shows the operational logic behind the build, not just the user-facing surface.

Key system pieces

Worker pipeline computes match scores and notification fan-out.

Vehicle lifecycle rules keep buyer and seller state transitions safe.

Mobile-first flows make the software operational instead of dashboard-only.

Core constraint

State consistency: vehicle lifecycle transitions must keep buyer and seller state safe across concurrent offer and inventory workflows

Proof status

This page separates what is already visible from what is still being prepared, so the proof layer can grow without pretending unfinished artifacts already exist.

Proof surfaces

Real artifacts stay visible. Missing artifacts are labeled directly so this page stays honest and ready for stronger proof later.

System Walkthrough

Available now

The mobile workflow shown on this page is still the clearest existing proof surface for DealerFlow.

Buyer-facing inventory feed and match workflow are visible through the mobile screenshot.
Pilot status is real, but the fuller walkthrough needs stronger artifact coverage than it has today.

Architecture / Flow (to be added)

In progress

The system architecture is real, but the dedicated diagram and lifecycle artifact still need to be added.

Notification pipeline diagram is still to be added.
Lifecycle-safe inventory model artifact is in progress.

Operational Surfaces

Available now

This system already has real operational surfaces even though the proof set is still thinner than it should be.

Mobile buyer workflow for incoming inventory.
Seller inventory and offer management flow.
BullMQ-backed notification handling for match and lifecycle changes.

Artifacts & Evidence (to be added)

In progress

DealerFlow still needs stronger embedded artifacts to become a more believable flagship.

Dedicated lifecycle diagram to be added.
Notification and queue artifact to be added.
More complete mobile workflow proof to be added.
