ErrandWaka - On-Demand Errand Management Platform

ErrandWaka is a mobile solution that bridges the gap between people who need tasks completed and verified runners ready to help. Built with Flutter for cross-platform excellence, the app creates a seamless marketplace for errand services with real-time tracking, secure payments, and trust verification systems.

The client needed a robust platform that could:

Handle two distinct user types (senders and runners) with different interfaces

Implement real-time GPS tracking for ongoing errands

Ensure secure, conditional payment processing

Build trust through comprehensive verification systems

Scale to handle thousands of concurrent users

Traditional errand services lacked transparency, real-time updates, and secure payment guarantees - issues that ErrandWaka aimed to solve through technology.

Frontend: Flutter 3.x for iOS/Android cross-platform development

State Management: Riverpod for complex multi-user state handling

Backend: PHP (Authentication, REST APIs)

Maps Integration: Google Maps API for real-time tracking

Payment Processing: Integrated Paystack payment gateway with escrow functionality

Push Notifications: FCM for instant task updates

For Errand Senders

Quick Task Creation: Streamlined flow to post errands in under 60 seconds

Runner Selection: Browse verified runner profiles with ratings and reviews

Real-Time Tracking: GPS-enabled live tracking from pickup to completion

In-App Messaging: Direct communication with runners

Payment Protection: Funds held in escrow until task completion

For Errand Runners

Task Discovery: Smart filtering by location, category, and payment

Earnings Dashboard: Real-time earnings tracking and payout management

Route Optimization: Integrated navigation for efficient task completion

Availability Toggle: Control when to receive task notifications

Performance Analytics: Track ratings, completion rate, and earnings trends

Implemented a sophisticated role-based system that dynamically adjusts the UI/UX based on user type, while maintaining a single codebase. This reduced development time by 40% compared to building separate apps.

Built a custom state management solution combining Bloc with Firebase listeners to ensure all parties see updates instantly - critical for time-sensitive errands.

Developed a multi-layer verification system including:

Government ID verification

Background check integration

Two-way rating system

Dispute resolution workflow

Implemented an escrow-style payment system where funds are held securely and only released upon task completion confirmation, protecting both parties.

Crash reduction through extensive error handling and recovery mechanisms

Sub-2 second load times using lazy loading and optimized asset management

Reduction in data usage through intelligent caching strategies

Battery-efficient GPS tracking using adaptive location update frequencies

The UI/UX leverages my design background to create an interface that's both beautiful and functional:

Color-coded task states for instant status recognition

Smooth animations that guide users through complex flows

As a technical writer, I delivered comprehensive documentation including:

Complete API documentation for future integrations

Detailed code architecture guide for maintainability

User manuals for both sender and runner interfaces

Admin panel documentation for business operations

This project showcased my ability to:

Build complex, multi-stakeholder platforms

Implement real-time features at scale

Design intuitive interfaces for diverse user groups

Write maintainable, documented code

Deliver production-ready applications on schedule

ErrandWaka represents the intersection of technical excellence and user-centered design - exactly the kind of impactful mobile solution I specialize in creating.
