What I'm looking for

I’m looking for a role where my app development and team leadership skills help scale an influencer marketing and AI-driven marketplace, supported by reliable, scalable engineering systems.

I’m an engineering leader with 10 years of app development and team leadership, specializing in mobile and frontend engineering. I focus on scalable engineering systems that help products grow reliably while keeping release quality high.

In my recent role as Engineering Lead (Mobile Apps) at SHEIN India, I spearheaded end-to-end mobile delivery and launched the iOS and Android application in India within a compressed 3-month timeline. I also optimized app launch times and improved operational visibility by integrating tools such as CRM systems, Firebase, Google Analytics, and performance monitoring frameworks.

At Zivame, I improved iOS launch time by 40% and Android by 35%, while achieving 100% security audit success through SSL Pinning, encrypted storage, and OWASP-aligned practices. I led CI/CD automation for iOS and Android, cutting deployment time by 50% and maintaining over 98% lint compliance, while driving product impact through payment and checkout enhancements.

Across roles at Zivame and earlier engineering positions, I’ve consistently improved conversion and user experience—whether by revamping checkout flows, remodeling home pages for offline support, or reducing code redundancy through reactive and MVVM/MVC-aligned architecture. I enjoy building cross-functional momentum with Product, UX Research, QA, marketing, growth, and CX teams, and I aim to keep engineering execution tightly connected to business outcomes.
