Book delivery
Instant and scheduled booking flows backed by an Express API that creates deliveries, prices them, and routes them into payment and dispatch states.

Logistics operations · Realtime dispatch
Evoke Logistics turns booking, payments, dispatch, and rider verification into one controlled system.
A production-grade logistics platform with instant and scheduled delivery booking, secure payment confirmation, NIN-gated riders, real-time dispatch, and route-aware operational workflows.

What I built
A logistics workflow engine, not just a booking form.
The product combines transaction integrity, dispatch operations, rider verification, and realtime status updates inside one operational flow.
02
Track delivery
Realtime delivery tracking via Socket.IO with a state machine covering payment, assignment, acceptance, transit, arrival, and completion.

03
Dispatch board
Dispatcher-facing assignment workflows with admin override so operations stay in control even when automated dispatch does the first pass.

04
Payments
Paystack initialization, verify, and webhook handling tied directly into delivery state transitions and post-payment dispatch automation.

05
NIN verification
Rider verification gates so unverified users cannot go online or be eligible for assignment in production workflows.

Geospatial routing
Leaflet, OSM/Nominatim, and OSRM wired together so route and distance data can support rider matching and dispatch decisions.

Paystack / NIN / Maps
External systems integrated into core workflow logic.
Engineering challenges
Integrity and operational control were the core challenges.
Area
Payment integrity
Problem
Deliveries should not complete or move forward on untrusted payment events.
Solution
Server verification and HMAC webhook checks ensure delivery transitions only happen on trusted payment confirmation.
Area
Auto-dispatch logic
Problem
Dispatching the wrong rider breaks logistics efficiency and trust.
Solution
Nearest eligible online rider selection uses vehicle matching, radius rules, and verification status.
Area
Realtime authorization
Problem
Tracking data should not leak across sessions or unauthorized listeners.
Solution
JWT-based Socket.IO authentication restricts realtime updates to valid users.
Area
Provider hardening
Problem
Production cannot silently accept invalid payment or identity states when provider keys are missing.
Solution
Production paths require real keys and fail loudly instead of pretending success.
Outcomes
Why the system is valuable.
Realtime operations
Dispatch and tracking work as a live operational flow rather than a static booking experience.
Secure payment pipeline
Payment correctness is embedded into delivery state transitions.
Verified rider control
Operational safety improves when assignment depends on trusted rider verification.
About
I like products where correctness matters operationally.
Evoke Logistics reflects the kind of product work I enjoy: payment integrity, role permissions, realtime status flows, routing, and operational correctness under live usage.
I build for what happens after launch, when data, users, and edge cases start colliding.
