I build secure iOS, Flutter, and tvOS applications for FinTech, emergency management, and real-time communication.
IndiaWhat I'm looking for
I've built five live iOS, Flutter, and tvOS applications, including SingX and SingX Business for international money transfers across 180+ countries.
At SingX, I improved responsive performance and real-time exchange-rate streaming while strengthening fraud protection with Passkeys, SSL Pinning, CAPTCHA, and biometric authentication.
Previously at E2 Infosystems, I delivered eMessenger, CATIE Mobile, and CATIE TV, migrated CATIE TV to the public App Store, and reduced release time by 30% through Fastlane automation. I also conduct technical interviews, train newcomers, review code, and own critical deliverables.
