Built the period tracker module (NestJS + Prisma): cycle predictions, fertility calendar, daily logs, bulk entry operations, and statistics.

Implemented a real-time conversations and messaging system supporting multi-participant chats, attachments, unread tracking, and a Kiki AI chat proxy that routes messages to an external AI service and syncs responses back.

Contributed to the internal admin dashboard (React, MUI, Redux) covering user management, expert profiles, a content CMS, subscriptions, role-based access control, and a clinical data dashboard for the health operations team.

Contributed to migrating the database layer from MongoDB to PostgreSQL across multiple modules, rewriting queries, restructuring schemas, and standardising date handling throughout the codebase.

Designed and built the entire platform as the sole engineer: a NestJS API, a Nuxt 4 admin dashboard, and two React Native apps (customer and rider), covering auth, real-time order flow, payments, and live location tracking.

Built real-time order tracking with Socket.IO; customers see their rider's live location on a map and order status transitions are broadcast to all parties instantly.

Integrated Paystack and Flutterwave for a wallet-based payment system with automated rider payouts, bank verification, retry logic, and fee breakdowns.

Built and published the customer and rider apps to the App Store and Google Play using Expo, with push notifications via FCM, deep linking, OTA updates via EAS, and CI/CD via GitHub Actions, Docker, and Fly.io.

Contributed to the Dumo product suite across three Nuxt 3 apps: Dumo AVA (online learning platform), Dumo Pali (digital marketplace for creators), and Dumo Cloud (account management and auth).

Built the course creation flow: curriculum editor, video/PDF/embed upload, drag-and-drop reordering, drip content scheduling, and multi-currency pricing across Paystack, Stripe, and Flutterwave.

Built the student-facing portal covering course catalogue, cart, checkout, a custom Video.js player, lesson comments, course reviews, and progress tracking.

Implemented server-side Hydra OAuth middleware for login/logout challenge flows and session management across all three apps.

Contributed to building a multi-app edtech platform across a student web portal, admin dashboard, partner school admin, and public site.

Built the student-facing web dashboard (React, RTK Query): course catalogue, quiz view with timer, quiz history, subscription management, profile settings, and school account linking via invitation flow.

Delivered a comprehensive admin portal for managing courses, lectures, quizzes, students, admins, and schools, including lecture sorting, quiz publishing, and platform feature flags.

Integrated LogRocket session tracking and Mixpanel analytics across the student app, admin portal, and public site.
