Google Play | 10M+ Downloads | 1.5M+ DAU | 4.6/5 Rating Cross-Platform Batch Listing (KMM) Took full ownership of rebuilding the batch listing using KMM — fixed the drop-off and confusion issues that were hurting conversion at 1.5M+ DAU scale. Shipped event-based listings, seasonal sales, topper highlights, and offline event discovery — features that made the product work for a much wider range of students. The changes led to an estimated $2.4M+ revenue impact from just a 0.10% conversion uplift, within 2-3 months of going live. Onboarding Optimization – PW App 2.0 Ran A/B tests and cleaned up the onboarding flow — moved signup success from 83% to 89%, touching around ~550K users. Got 3% more users into the right cohort and reduced same-day switching by 3% — small numbers, real retention impact. AskDoubt – Real-Time AI Tutoring Revamped AskDoubt from one-time API calls to a persistent WebSocket connection, unlocking real-time 1:1 student–AI teacher conversations and scaling to ~1.5K daily active users. Built a gamification layer with XP and leaderboards — in 5 weeks it pushed +211% DPP usage, +206% test participation, and +64% video watch time.

Integrated fingerprint biometric SDKs to enhance authentication reliability across MDM-managed enterprise devices. Built an Analytics SDK from scratch covering session management and event tracking, intentionally kept it under 50 KB by using Android's built-in APIs so the host app stays lean. Prevented data loss and duplicate submissions in poor network conditions by implementing offline-first submission with local persistence and WorkManager based background retry. Grew the Android team from 0 to 3 engineers through recruitment and onboarding, resulting in noticeably improved sprint velocity, PR throughput and code quality.
