Next.js 15, TypeScript, Python FastAPI, Cloud Microservices & Distributed Web Systems
Master modern full-stack application development. Build resilient cloud backends, high-performance web frontends with Next.js App Router, secure REST and GraphQL APIs, distributed database schemas with PostgreSQL/Supabase, and automated CI/CD deployment pipelines on Vercel and cloud compute.
Built for practical execution across African operating realities. Study online or export complete lesson guides for offline learning.
In Nigeria, mobile internet (MTN, Airtel, Glo) suffers from packet loss, high RTT (>120ms to foreign regions), and sudden drops. Frontends must implement optimistic updates, offline caching, and aggressive compression rather than assuming constant gigabit fiber.
Sudden cellular handovers between 4G and 2G (EDGE) cause API requests to hang indefinitely. Service Workers intercept outgoing payloads and persist them locally in Dexie.js / IndexedDB before background sync attempts.
Develop a type-safe, high-concurrency in-memory key-value cache engine featuring Least Recently Used (LRU) eviction and TTL expirations.
