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.

Cover image for VEDV
One app, four roles, turning

VEDV One app, four roles, turning printed textbooks into a connected school platform. Overview VEDV is a Flutter app (iOS, Android, web/desktop) that serves as VEDV Publication's all-in-one school platform. From a single codebase it presents four different experiences based on login , Student, Teacher, School Admin, or Guest/Parent with UI gated by role flags. At its core, it turns printed textbooks into connected digital lessons: students scan a QR code on a physical book and land directly on the matching video, PDF, quiz, or test. Around that sits a full learning library, three Gemini-powered AI assistants, and a School Hub that auto-generates school documents all layered over one educational-safety policy that keeps AI responses age- and subject-appropriate. For teachers and admins, the same app doubles as a school-operations backbone: attendance, marks, marksheet and ID-card generation, certificates, fees, notices, calendars, and real-time 1:1 chat. The Problem Schools run on disconnected tools one system for content, another for attendance, spreadsheets for fees, WhatsApp for parent updates with no link between a printed textbook and any digital follow-up. A publisher's book is a dead end once printed. The result is duplicated data entry and no single, trustworthy view into a child's attendance, results, or fees. VEDV bridges that gap: one role-aware app where the QR scan turns a static book into an interactive lesson, and the same platform runs the school's day-to-day operations so content and operations reinforce each other instead of living in silos. Key Features QR Book Scan — Scans a printed textbook's QR code and opens the exact matching content (video, PDF, quiz, audiobook), filtered by role, students see learning material, teachers additionally get lesson plans and answer keys. AI Assistant with Chapter-PDF & Multi-Format Export (Unique) — Type, speak, or photograph a question; the AI answers grounded in the actual chapter PDF and can export a real downloadable worksheet, lesson, or presentation as PDF, PowerPoint, or Word. School Hub AI Design Generator (Unique) — Describes a poster, ID card, or notice in plain language, asks smart follow-up questions, then generates a print-ready design using the school's real logo and brand colors. STEAM-L AI Tutoring Suite (Unique) — Six subjects (Science, Tech, Engineering, Arts, Math, Languages), each with an AI tutor, auto-generated quizzes, an English corrector, and a full voice-mode conversation gamified with streaks, XP, and hearts. Tech Stack Mobile: Flutter · Dart · GetX (state, routing, DI) · GetStorage (local persistence). Backend: REST API via Dio · Laravel · MySQL · Firebase (Auth, Realtime Database for chat/presence, Cloud Messaging). AI: Google Gemini (routed through a shared safety-guardrail layer). Infra: GitHub · Sentry (crash/performance monitoring). Results & Key Takeaways AI responses are unreliable in raw form the real fix was building a robust clean-up layer that recovers useful content even from malformed AI output, rather than trusting the model directly. Never hard-wire a single AI model each request tries a preferred model and falls back through alternatives with retries, since models get updated or retired often. Security gap flagged for next iteration: AI API keys currently live inside the app itself and should move server-side before wider distribution. The same AI-handling logic (retries, fallbacks, safety rules) was duplicated across features next step is consolidating it into one shared component. The "one app, four roles" model worked well but role-permission logic is scattered across screens recommend centralizing role management into a single control point.

Cover image for New one is up: Kreis.
It

New one is up: Kreis. It came out of my cycling club near Salzburg. Every family bike day ends the same way - a few hundred photos scattered across phones and chats, and afterwards nobody can find anything. So we built one private album for one group. In September we tested it on the real thing: people scanned a QR code at the stations and their photos went straight into the shared album — no app to install, no account. A hundred by the evening. 154 now, because people kept adding theirs afterwards. It sorts photos by day on its own, keeps likes and comments next to the pictures, and holds everything in full quality. No ads, no tracking. Two of us built it: I do product, releases and support, my partner does web. On the App Store and Google Play — and the next features I'm building with my clubmates first. https://apps.apple.com/us/app/kreis-private-photo-groups/id6803855914 https://play.google.com/store/apps/details?id=com.enidev.kreis

Cover image for MushTrail helps you never lose

MushTrail helps you never lose your way in the forest. It records your path over GPS and always points you back home — fully offline, using just GPS and a compass. Built for mushroom foragers, it works for anyone who wanders off the trail. The idea and most of the engineering are Ivan's @Ivan Lukichev . I owned the part that takes a strong product and gets it into people's hands: • Localization into 8 languages (EN, DE, PL, FR, CS, FI, SV, RU) • Full ASO — names, subtitles, keywords, descriptions per locale • App Store Connect setup, subscriptions, and submission • Handling the App Review process end to end, including a Guideline 2.1 review round Result: approved and live on the App Store 🌲

Cover image for I went through it as

I went through it as if I were a founder deciding whether to hire you. This is the version I would publish. While testing Expirel as a public user, I identified a usability issue in the email verification flow that resulted in a confusing authentication error after successful verification. I documented the issue with clear reproduction steps, expected behavior, actual behavior, and testing environment details before submitting it to the product team. The team successfully reproduced the issue, acknowledged the UX concern, and later confirmed that the reported bug had been fixed. This case study demonstrates my approach to identifying reproducible issues, communicating them clearly, and contributing to product quality through structured QA and UX testing. If you’re building a SaaS, mobile, or Web3 product and want critical issues identified before your users find them, I’d be happy to help.
