Technical Mentorship: Provided expert guidance to a network of digital entrepreneurs on scaling store operations, automating order fulfillment, and navigating Fintech compliance requirements (KYC/AML). System Automation: Leveraged ADB and custom automation scripts to monitor transaction success rates on mobile devices, ensuring 100% compatibility across various Android-based payment apps. Vendor & API Coordination: Collaborated directly with third-party Fintech providers to customize checkout experiences and troubleshoot real-time network driver issues affecting transaction stability. Project Management: Led the transition of static web apps to fully dynamic commerce platforms, integrating secure passcodes and multi-tenant backend architectures for diverse client needs.
