I contributed a mature tooling environment in VSCode for software engineers developing for Huawei's Internet of Things platform and mainly worked with JavaScript and TypeScript

11/2015–07/2017
Design and development of new services like Same Day Delivery, Sunday Delivery, and making a precise delivery date calculation for cross-dock items
Backend: Mainly using Java Spring to develop high performant and resilient webservices that use Oracle or Postgres databases
Frontend: Using AngularJS and Angular 2+ for client-side applications
20% Project: At bol.com I initiated the start-up of a group which provides tech trainings internally. I developed a Java Spring training myself and guided several senior developers in making trainings about their expertise. These trainings were then published in the "bol.com academy" which I developed as a 20% side project. The code for the academy was written in Go and the trainings were written in Asciidoc. All trainings have a continuous deployment pipeline to make sure they can be updated easily. Some trainings, including my Spring training, are open-sourced on Github. The academy was a great success, all new junior engineers at bol.com take several of the trainings on the bol.com academy as part of their onboarding process.
Listed below are some examples of programming languages and technologies I have gained experience with through my work in software engineering and academic research:
At UC San Diego I conduct research in CS Education on how we can better prepare CS students for careers in industry. At National Taiwan University I conducted research in Mobile HCI.

During this term I integrated my tech stack for auto grading student test quality into the C++ programming assignments. At the end of the term, the 415 students reported writing an average of 10.00 tests per assignment (median = 10, sd = 6.59).
