job
Android developer
Intelligent Environments.
Financial Services industry. We had one very large and complicated white label app and we
customized it for our clients. I worked on both, mainly as part of agile scrum teams.
• On the white label app:
• Led the migration from Eclipse to Android Studio and introduced Artifactory to our
project which led to the adoption of it by the whole company. Also improved the TeamCity build process.
• Optimized our large Android Studio project with more than forty libraries to build
relatively quickly.
• Worked on a lot of new features and changes like server credentials login, sign in from third party app, pattern login or material design.
• Customized our app to include Emoji sign in, what became quite famous:
• https://vimeo.com/134091434
• Ensured PCI security standard compliance.
• In client delivery projects (mostly parallel to the white label work):
• Liaised with QA, Business Analysts and Project Managers to ensure customer
satisfaction. Became the sole source of information regarding Android development and technical feasibility.
• Customized our mobile financial services platform according to specification. This
includes mainly changing colours and copy text, but also adding new features like Apply
for Thinkmoney.
• Worked on an Android middleware for Atom Bank.
• I was the sole developer for the first deployments of the company on Google Store for
clients like CapitalOne, ING and Swisscard.
• Streamlined the development and the build process.
• App links: I'm afraid the links to Google Play are not relevant anymore.
