Cover image for RandaLogs Rider — Mobile Delivery
RandaLogs Rider — Mobile Delivery Rider App Overview RandaLogs Rider is a cross-platform mobile application built for delivery riders and courier drivers in Nigeria. The app manages the complete rider journey from phone verification and document approval to receiving nearby delivery jobs, navigation, real-time tracking, customer communication, delivery completion, and cash collection. The application was delivered for both Android and iOS using Flutter. Problem Statement The delivery platform needed an efficient way to assign orders to available riders based on proximity and track each delivery until completion. Riders needed a mobile-first workflow that allowed them to quickly accept jobs, locate pickup and drop-off points, navigate between locations, update delivery status, communicate with customers, and manage Cash on Delivery orders without relying on multiple tools. Solution RandaLogs Rider brings the full delivery workflow into one application. After verifying their phone number, riders complete registration by uploading identity and vehicle documents for approval. Once approved, they can go online, continuously share their location, receive nearby orders in real time, view routes on a map, complete deliveries, and update payment and delivery statuses. Key Features OTP Authentication: Firebase Phone Authentication verifies riders through SMS before account creation. Rider Verification: Riders upload ID and vehicle documents, with access to orders restricted until approval. Online Availability & Live Tracking: Riders can switch online while foreground location services continuously send their position. Nearby Order Assignment: Current rider location is sent to the backend, which assigns nearby delivery requests. Real-Time Order Updates: Socket.IO (http://Socket.IO) keeps location, order state, and delivery activity synchronized. Maps & Navigation: Google Maps SDK and Directions API display pickup/drop-off locations and route polylines. Delivery & COD Management: Riders update pickup and delivery states and record cash collection at the required stage. Customer Chat: In-app messaging allows riders to contact customers without leaving the delivery workflow. Push Notifications: Firebase Cloud Messaging and APNs notify riders about new jobs and order updates. Technical Highlights The app was built with Flutter and Dart, using GetX for state management and dependency injection. A custom REST API handles backend communication, while Socket.IO (http://Socket.IO) supports real-time events. Firebase provides Phone Authentication, Cloud Messaging, App Check, and Crashlytics. Device location is captured through Geolocator, with foreground services maintaining updates while riders are travelling. Challenges & Solutions A key challenge was maintaining reliable live location while handling different Android and iOS permission requirements. The implementation combined native permission flows with foreground location services and required additional work to satisfy Apple’s review requirements. Real-time synchronization between rider location and order status also required careful Socket.IO (http://Socket.IO) handling. Results & Impact The two-person team completed the project in approximately two months and shipped the rider application on both Android and iOS. The finished product supports the complete operational flow from rider onboarding and verification through order assignment, navigation, delivery tracking, communication, and cash collection. Key Takeaway RandaLogs Rider demonstrates how real-time location, logistics workflows, mapping, authentication, and payment-status handling can be combined into a focused mobile experience built for riders working continuously on the move.

Making real progress on the Dart & Flutter learning app! 🚀 I’ve been heads-down architecting the core curriculum structure and building out the topic data models in VS Code. Instead of just surface-level theory, the app is built around interactive code snippets, deep-dive video integrations, and real-time knowledge checks covering core mechanics like implicit animations, layout rendering, and state management. Current Dev Milestone: Structured clean Topic and QuizQuestion models with strict type safety. Built out over 1,000+ lines of interactive curriculum data. Integrated direct YouTube video bindings for multi-format learning. Next up: Connecting the state management and building out the interactive UI components.

Cover image for A secure, cross-platform FinTech mobile
A secure, cross-platform FinTech mobile application built to digitize the traditional "Ajo" or "Esusu" rotating savings and thrift contributions. This application provides users with a seamless platform to manage collective group savings, fund digital wallets securely, track cycles, and withdraw payouts directly to their bank accounts. Key Features & Architecture Implemented: Digital Wallet & Gateway Integration: Developed custom wallet interfaces featuring transaction logic, balance privacy toggles, and live payment processing wrappers (utilizing Paystack integration for secure local and international card funding). Automated Ajo Board Tracking: Engineered a dynamic rotation dashboard showing member statuses (e.g., "Collected", "Next to Collect", and "Pending") with custom progress tracking gauges showing completed cycles. Financial Ledger System: Designed clean user dashboards for tracking transaction histories, separating "Wallet Funding," "Contributions," and "Withdrawals" with explicit visual color coding for credits and debits. State Management & Fluid Navigation: Built using modern mobile design principles, ensuring seamless page-to-page navigation, rapid micro-interactions .
