Problem-first engineering, not app showcases.

Approach

Profiled rendering pipelines and hot paths under realistic load. Optimized cell rendering, prefetching, and image decoding. Modularized the feed into composable, independently testable units.

Impact

• Smoother UX under scale
• Reduced UI jank on long sessions
• Lower memory pressure

Approach

Designed a structured event tracking layer for iOS and Android with shared taxonomy and type-safe contracts. Spearheaded rollout across the entire mobile platform — from definition to dashboard.

Impact

• 300+ events tracked in production
• Decisions moved from intuition to data
• Cross-platform parity at the schema level

Approach

Incremental refactor with abstraction layering. Introduced seams and tests around critical paths so feature work and stabilization could ship in parallel without blocking each other.

Impact

• Stability improved without slowing shipping
• Reduced regressions on touched modules
• Cleared a path for ongoing modernization
