Experience Highlights

2Talk – Chat & Voice Call Platform for Emotional Support

2Talk is a VC-backed platform connecting users with supportive listeners via chat or voice calls. Users can top up seamlessly using e-money integrations, and even apply to become a “talent” to earn while helping others. I led the mobile development using Flutter, architected the system to support real-time communication, and implemented smooth onboarding, payment, and profile management flows. The app empowers emotional expression while creating side-hustle opportunities for everyday listeners.

Coffee Farm – Loyalty App for F&B Businesses

I led the end-to-end mobile development for a loyalty system designed for F&B businesses. The app allows users to collect points from transactions and redeem them for rewards directly through the platform. It features WhatsApp OTP login, a clean and intuitive UI, and is fully integrated with our custom backend. I was also involved in product and system design, collaborating with the backend engineer to craft scalable API contracts and optimize the user flow. The app is published on the Google Play Store.
