01 // THE PROBLEM

In Ethiopian secondary schools, students consistently face severe academic barriers due to fragmented textbooks, lack of centralized curriculum materials, uneven educational resource access, and absence of structured self-testing tools across Grades 9-12.

02 // LOCAL CONSTRAINTS

Most secondary students access the internet through low-cost mobile smartphones with limited monthly data quotas and periodic network drops.

03 // ENGINEERED SOLUTION

Built a comprehensive high school educational platform paired with an automated Telegram bot delivery engine and high-performance microservices. Serves complete curriculum notes, digital textbooks, weekly credit-based mock exam sessions, and automated scoring analytics. Architected with custom PHP on a Laravel-based architecture, HTML & Tailwind CSS, a high-throughput REST API, an integrated custom-built AI Gateway, MySQL on cPanel, and Node.js & Fastify services to handle concurrent student submissions without expensive cloud scaling.
