Project Details

Logipartner is a highly secure, end-to-end delivery application designed around the "glanceable at speed" and "one-thumb operation" principles, giving partners everything they need to maximize earnings.

  • Comprehensive Partner Onboarding & KYC: Built a highly secure, multi-step onboarding funnel that allows riders to submit identity documents (Aadhaar, PAN, DL, RC) and capture live profile selfies.
  • End-to-End Order Lifecycle: Engineered a frictionless delivery workflow guiding partners through every step: FCM Order Alert ➝ First-Come Acceptance ➝ Store Pickup ➝ OTP-Verified Drop-off ➝ COD Cash Collection.
  • Dynamic Earnings & Wallet Dashboard: Developed a detailed analytics dashboard allowing partners to visualize daily, weekly, and monthly earnings charts. Includes a complete ledger of delivery fees, COD dues, and instant withdrawal requests.
  • Live Location & Fleet Dispatching: Implemented continuous background GPS synchronization (pinging every 5-10s) to accurately map nearby drivers to incoming orders based on proximity.
  • Offline-First & Distraction-Free UX: Designed entirely around the "glanceable at speed" and "one-thumb operation" principles. The app features robust network error recovery, automated offline banners, and auto-sync capabilities for riders in poor connectivity zones.

Technical Overview

A secure, serverless architecture that handles complex geospatial queries and atomic multi-table transactions in real-time.

  • Atomic Transactions & Race-Condition Safety: Leveraged custom PostgreSQL RPCs (e.g., complete_delivery) to handle multi-table atomic operations safely. This ensures order status updates, partner earning calculations, and platform/seller fee splits occur seamlessly without data corruption.
  • FCM Data-Only Payloads for Background Execution: Engineered background and terminated state handlers in Flutter that parse FCM data-only payloads to trigger immediate, high-priority native pop-up alerts before the user even opens the app.
  • Secure Multi-Part File Handling: Integrated multipart/form-data API endpoints that strictly validate file size (<50KB) and MIME types before piping KYC images securely into Supabase Storage buckets.
  • Optimized Geospatial Queries: Handled real-time geospatial data by updating driver latitude/longitude via PATCH requests, allowing the backend to efficiently query active fleets and dispatch tasks.
  • Client-Side OTP Auth Strategy: Designed a decoupled authentication architecture where the Flutter client natively handles Supabase Magic Links/OTP verification, securely passing authenticated Bearer tokens to the Vercel REST API for protected routes.
