Jean-Francois 'Jeff' Moy



I believe in Software Craftmanship; I am passionate about Software. I design and implement well structured, robust, and maintainable software.

I value agility, adaptability and proactivity: to new requirements, to new needs, to new technologies, to new environments.

I learn from others: from my team, from my peers, from the community.

I believe in sharing my knowledge and promoting these values through technical leadership.

Technical Lead - Ksubaka - London, United Kingdom

January 2015 - December 2015

Working as Technical Leader with a team of developers, DevOps and QA engineers across the whole Ksubaka platform.

My main focus was around designing and developing the Ksubaka platform that serves MoJos (Moments of Joys) to thousands customers across Asia (notably Singapore, and China). I served as interface and coordinator between the different technical teams and coordinated the development across the platform.

In terms of software development, I mainly contributed to the Android platform that powers our in-store devices. We followed the best practices and ensured our code was of very high quality and stability with a test driven approach. We relied on reactive programming (RxJava) for handling complex multi-threaded operations, and modern libraries such as Dagger 2 & ButterKnife for dependency/views injection, Picasso, etc. Cucumber and Robotium composed the foundation of our automation and integration testing.

I also sporadically contributed to the the backend platform that runs on a traditional J2EE stack (Hibernate, SpringMVC, etc.) and to the design and development of our internal web applications based on AngularJS.

I also led the recruitment and interviewing of candidates for our software developers and quality insurance job openings.
