Architectural Decisions

Key technical decisions that shaped platforms

Feb 26, 2013

Decentralized Database Architecture

E70 EdTech Platform
platform Active

Monolithic database was becoming a bottleneck for 30+ applications with independent release cycles and scaling needs

Implement decentralized database architecture where each application maintains its own database, with ContentProviders for cross-app data sharing

Enables independent module scaling, reduces coupling, allows apps to evolve independently, and improves overall system resilience

My Ownership 100%

Adopted as standard pattern across all 30+ E70 applications, enabling independent release cycles and horizontal scaling

AES-256 Encryption via JNI

E70 EdTech Platform
platform Active

Premium educational content needed enterprise-grade protection from unauthorized access and piracy

Implement AES-256 encryption in native C code via JNI for performance and security

Native implementation provides better performance and is harder to reverse-engineer than pure Java

My Ownership 100%

Protects premium content for Samsung, Cambridge, Britannica partnerships worth millions in licensing
