As a result, the application broadened its user base through engaging features that cater to both advanced and novice users. ● Established a virtual currency system decoupling AI training costs from image production costs, increasing revenue flexibility and simplifying the purchase journey. ● Integrated multiple payment methods (in-app purchases on iOS/Android and mobile money solutions) to broaden market reach and remove barriers for a global user base. 3) Technologies employed: Flutter and Dart, Firebase (Authentication, Firestore, Storage, Messaging, Cloud Functions), Replicate API (Flux, SDXL), Riverpod, RevenueCat, In-App Purchases, Mobile Money APIs.

1) Context Abemi emerged from my personal experiences in Mali, where I encountered challenges in discovering and accessing local businesses without prior guidance. Designed to revolutionize user interaction with small enterprises in Africa, Abemi is an innovative mobile application that enhances the discovery of local information, thereby improving accessibility and engagement with these businesses. Abemi embodies my enthusiasm for creating innovative solutions that address specific needs, alongside my capacity to manage a complex project from inception to completion. My dedication to technical excellence and positive social impact is central to this initiative, which I am honored to present to you. 2) Achievements ● Launched the Abemi mobile application to tackle the lack of accessible local information in Africa, empowering users to quickly discover and connect with small businesses (restaurants, entertainment venues, etc.). ● Developed intuitive search and navigation features (including direct contact integration), streamlining the user journey and boosting overall engagement with local enterprises. ● Fostered a user-driven community where members actively contribute and verify business details, ensuring a constantly evolving and reliable database of local information. ● Deployed a scalable backend (BunJs, Prisma, ElysiaJs, AWS S3, and PostgreSQL) with a Flutter front-end, ensuring a resilient infrastructure and a smooth user experience across platforms. 3) Technologies employed: Frontend: Flutter facilitates cross-platform development, guaranteeing a seamless and responsive user experience. Backend: BunJs and Prisma facilitate efficient data management and backend queries, while Elysia Js handles server query processing. PostgreSQL serves as the database, ensuring robustness and scalability, and Amazon Web Services S3 is utilized for file storage.

1) Context An increasing number of African creators are emerging on social media platforms such as YouTube, TikTok, and Instagram, generating substantial content and cultivating communities of millions of followers. Despite these large audiences, views from African users are typically not monetized, greatly limiting creators’ income. Moreover, African fans often lack viable ways to support their favorite creators, as many global platforms do not integrate region-specific payment methods like mobile money. The YELEN app addresses these gaps by offering a dedicated platform where African creators can monetize their work and where local supporters can directly engage and contribute using payment methods tailored to the continent. 2) Achievements ● Conceived and launched the YELEN app to bridge the monetization gap for African content creators, allowing them to earn revenue directly from their passion and content. ● Implemented user-friendly features (phone number authentication, direct messaging for premium subscribers, multi-language support) to enhance engagement and strengthen creator-community interactions. ● Established robust user management and moderation tools (account restriction, reporting system) to foster a secure environment and maintain platform integrity. ● Deployed the application on iOS and Android using Flutter, optimizing the user experience through an intuitive interface (dark/light mode) and integrating Sentry for rapid issue resolution. 3) Technologies employed: Flutter, Firebase, TypeScript.
