About the Project

We are building a mobile logistics and transport app. The app connects customers with transport providers (drivers, crane operators, container carriers, etc.) for local and national delivery of goods. .

Our mobile developer (working in Kotlin with Jetpack Compose) is already building the frontend with Firebase and Supabase. We now need a backend developer to help structure and implement a reliable, scalable backend system that supports real-time transport requests, bidding, document uploads, verification, and more.

Your Role

You will be responsible for:

Designing and implementing the backend architecture
Creating RESTful or GraphQL APIs for use in the mobile app
Setting up and managing PostgreSQL (Supabase or self-hosted)
Implementing user roles (Customer, Transporter, Admin)
Handling document upload logic and secure storage
Integrating OTP (via SMS/WhatsApp) and optional email login
Supporting future features such as B2B accounts, analytics, and in-app payments

Tech Stack We Prefer

Node.js / NestJS (preferred)
PostgreSQL / Supabase
Firebase (Auth / Cloud Messaging)
REST API (GraphQL is a bonus)
Docker / Railway / Vercel / Render (optional deployment tools)
Experience with Firebase Functions (nice to have)

Collaboration

You will work closely with our Android developer. Clear communication, accountability, and efficiency are key. We use Trello, Google Docs, and WhatsApp for coordination.
