At DevCache, I architected a Redis distributed caching layer with event-driven invalidation, cutting database load by 50% and achieving sub-50ms response times. I also built a Dockerized CI/CD pipeline that achieved 99.9% production uptime.
At LEWO, I built a monetization system with RevenueCat, in-app purchases, and A/B-tested paywall and onboarding flows that grew subscription revenue by 20%. I also architected a shared monorepo for four apps and implemented OTA updates, FCM push, and deep linking.
At Hashstackdevelopers, I architected SSR Next.js applications with optimized data fetching for sub-second page loads. I also built a Stripe transaction system with verified webhooks and live order tracking for a multi-vendor marketplace.
Across FinTech, SaaS, and e-commerce, I’ve built and launched 5+ iOS and Android apps with 15K+ downloads and 1K+ active users. VaultPay reached 10K+ downloads with multi-currency wallets, virtual cards, and live social commerce; I also contributed full-stack inventory features to Versa Cloud ERP.
