I've built AI tutoring, automated quiz generation, and structured content delivery for Temaribet's PrepX platform, serving thousands of Ethiopian high-school students. I designed REST APIs with average response times under 100 ms and Python automation that shortened content-production cycles.

At Apex Dynamics, I built GDPR- and DIN 33430-compliant reporting interfaces for a multi-tenant assessment SaaS platform serving DACH enterprise customers. My reusable table framework supported 50,000-row datasets within a p95 render budget of 800 ms, while accessible, localized interfaces served English, German, French, and Italian users.

I've also delivered offline-first learning systems, high-concurrency order management, subscription automation, and real-time collaboration tools using Go, Python, React, Next.js, and PostgreSQL. I own work end to end, from specifications and schemas through APIs, UI, testing, and CI/CD.
