Dhamodaran Narayana Perumal — Mobility Product Lead & Technology Consultant

About

Product leadership meets low-level performance.

I lead cross-functional squads delivering mobile-first digital banking across 10+ global institutions, blending hybrid (Ionic/Cordova/Capacitor) and native (Android/Java/Kotlin) mobile engineering with ultra-efficient backend modernization using Java 21, GraalVM AOT, Helidon, and Spring.

My work sits at the intersection of AppSec and performance engineering: RBI-compliant guardrails, SSL pinning, RASP integration, Burp Suite–led VAPT closure, monolith-to-microservices migrations, and cold-start optimization via Closed World Assumption builds and Native Images.

Based in Chennai, India · consulting engagements welcome.
