Good2Go is a peer-to-peer marketplace app for Nigeria where users can buy and sell secondhand or new items (clothes, electronics, home goods, etc.).

• Designed and built a cross-platform marketplace app using Flutter & Firebase, enabling users to buy and sell clothing and items.
• Developed core features, including real-time chat, notifications (FCM/APNs), search & categories, payments, and admin tools.
• Led technical architecture and integrations with Firestore, Firebase Auth, Storage, and Cloud Messaging.
• Drove product vision and execution, ensuring the app is optimised for Nigerian users and localised market needs.
• Liaised with key stakeholders to translate technical needs into product development strategies.

Identity & Access Control System (Flutter + Firebase)

Developed a cross-platform mobile application for government–citizen access management to regulate entry into subsidised food shops. The system ensures fair use by enforcing one-person-one-use rules and weekly spending limits.

• Built multi-screen flows (login, registration, check-in, completion, error handling)
• Designed validation logic for Identity inputs: Citizens can check in with their NIN ( National Identity Number), which is strictly 11 digits or their Voter's Card, which is an alphanumeric 9-digit serial with the first character as a letter.
• Implemented conditional navigation. New and existing users interact differently with the system.
• Developed a database that houses citizens' data on Firestore and created a shared identity layer so multiple identifiers (NIN, VC) map to the same citizen.
• Designed schema for identity data, access tracking, and cross-linking IDs.
• Implemented 7-day lockout mechanism across both NIN and VC identifiers (enforcing one-week entry regardless of ID used).

This system can be seen on my GitHub, which I initialised with .gitignore.
