* iOS App UI Automation Testing with RobotFramework and Python* App maintenance to include new features, bug-fix and integration with third-party’s* Generate a variety of tools for the team to optimize the development process like Fastlane, Makefile... etc.* Using TDD (Test Driven Development) to create main features like GraphQL API, streaming player sdk (from Objective-C to Swift)* Non-stop learning on new technologies like SwiftUI, Widget, Combine, Sign In With Apple... etc. in order to facilitate more apps in different platform* Good in Xcodegen to split big projects into small or well-maintained SDKs to minimize the trouble-shooting or development resources.

* Lead the mobile team, 7 engineers excludes myself, to finish the integration between two apps, digital e-ticket and Opay. * Develop and maintain two apps, one is to publish the ticket and the other one is to buy the ticket. * Develop the live video streaming app, "wwlive".* Recruit new person to join my team.

* Port the ICE, Interactive connectivity establishment, onto the ARM-based main board.* Customize the Chromium OS* Customize the Ubuntu OS* Python GTK application

* Build the app, mydlink+, for the iPad device from the beginning less than two months. This app connects all the devices under one user ID either through the local LAN, or the DNS(all name), or the UDP hold punching. All the devices will be bound into the mydlink server which is a cloud server. There are four kinds of devices and functions I used to program for IP-CAM, Router, NVR and NAS * Co-ordinate with the use experience team to define a user friendly interface. * Co-ordinate with the firmware team to achieve the required functions or the issues. * Define the process to improve the quality of the multiple channel video streaming. * Assist the colleagues to get familiar with the Objective-C architecture.
