App Platform 

 Performance , Observability & Instrumentation  

Performance Foundations

• Defined core mobile metrics: TTI & TTP

• Built custom performance measurement library

• Integrated metrics into Datadog dashboards with alerts

Performance Impact at Scale

• Home Page TTI ↓ 69% (1.6s → ~500ms)

• Checkout WebView load ↓ ~50% (6.5–7s → ~2.5s)

• System-level improvements:

  • 60 FPS scrolling

  • CPU ↓ 16–41%

  • RAM ↓ 2–5%

• High-traffic surfaces impacted:

  • CLP (~8.3M weekly visits)

  • Search (~2.6M)

Garuda SDK — Analytics at Scale

• Unified analytics SDK (Android & iOS)

• ~100M IA + ~64M Mixpanel events/week

• Zero event loss with automatic buffering & recovery

• Zero performance impact, as calculations are handled natively.

Reliability Lifesaver

• Despite a 3-day IA services outage, all events were buffered and recovered automatically by the Garuda SDK.

Tooling

&

In-House Solutions

Release Automation & Branching

• Automated release branch creation via CI

• Auto-sync to keep develop as single source of truth

• Custom Forge merge checks

  • Ensures hotfix/betafix commits exist in develop

  • Auto-syncs safe commits, blocks risky merges

• Improved iOS versioning logic

Impact

• Fewer release-time errors

• Faster, predictable releases

• Company-wide platform reuse

In-House Build System

• Reduce build time by 50% (currently ~10 min per build time)

• Added capability for parallel builds (currently 5 builds can be extended to 10)

• Integrated with bitbucket CI 

Impact

• Faster CI feedback

• Lower infra costs

• Scales with org growth

Developer Options (Internal Tooling)

• Network Logger

  • Live API visibility inside app

  • Removed external tooling dependency (Charles)

• Preview Mode Toggle

  • Prod ↔ preview without new builds

  • ~50% build cost reduction per release

Presentation Layer

                 &

Growth Enablement

Presentation Layer (PL)

• Widget-based, backend-driven UI system

• Dynamic UI updates without app releases

• Version-based controls for safe rollouts

• Reduced BFF risks (caching, tight coupling, dependency churn)

Current

• Collection Page rendered via PL

Marketing & Deep Link System

• Centralized deep link routing with slug-based resolution

• Supports:

  • Universal links / app schema

  • Deferred deep linking across install states

• Integrated with AppsFlyer

  • Email (Iterable), SMS (Attentive), Affiliate (Impact)

• Attribution, UTM & channel-level insights

Impact

• ~39% of app orders driven via deep links

• ~$70M of $180M app revenue

Core & Foundation 

React Native upgrade

• Reduced risk from deprecated or unsupported libraries

• Improved app stability across devices

• Future-ready platform that scales with product growth

• Improve memory usage

• Unblock future RN ecosystem upgrades

New Architecture

• Faster app startup → better first impression & higher conversion

• Smoother user experience 

• Improve memory consumption

• Better FPS 

What Next 

Tooling & In-House Solutions

• Eliminate third-party OTA dependency

• Full control over rollout, delivery & security

Developer Options

• Slug-based search

• Feature gate toggles

Core & foundational
