I’m in the middle of architecting a full-scale logistics and shipping platform—think along the lines of what DHL or Aramex run internally—and I need a hands-on developer / tech lead to push the web component over the line. Current scope • Web-based control centre that shows real-time shipment locations, status updates, and ETA calculations. • Dispatch management tools so operators can create, assign, and reroute jobs on the fly. • Robust API layer and webhook system for integrations with e-commerce storefronts, ERP/WMS solutions, and any future mobile courier apps we spin up. Where you’ll step in I already have early wireframes, a feature backlog, and sample data feeds from telematics partners. Your job is to turn that groundwork into a production-ready web application: design the architecture, pick the tech stack you’re most productive with, write clean code, and set up CI/CD so deployments stay painless. If you’re comfortable mentoring a small in-house team as we scale, that’s an extra win. Tech highlights I expect to see • Real-time data streaming (Socket.io, SignalR, MQTT, or a similar approach) • Solid mapping/geo-services experience (Google Maps, OpenLayers, Mapbox, etc.) • RESTful and/or GraphQL APIs with token-based security • Scalable database design (PostgreSQL with PostGIS, MongoDB, or equivalent) Acceptance criteria 1. A running web MVP deployable on a clean cloud instance. 2. Shipments update live on the tracking dashboard with sub-second latency under expected load. 3. Dispatch board supports bulk job import, drag-and-drop reassignment, and status auditing. 4. Public API docs (OpenAPI/Swagger) covering the integration endpoints. 5. Automated tests covering the core business logic. Timeline is flexible enough to let you do it right, but I’d like an initial milestone—tracking dashboard + basic dispatch—in about six weeks. If all goes smoothly we can later branch into iOS/Android courier apps, and you’ll have first refusal on that work. Let’s talk through your relevant experience and outline a roadmap together.
