Software engineer at Wirecard
I joined the Wirecard in October 2014 as software engineer. Since then I've worked on several projects:
WebUIThe WebUI is fronted application (SPA) to manage financial account/s (similar to PayPal but better ;)). This was the first project I joined in Wirecard. When I joined the team, the project has not been on production and it haven't had a lot of features yet. The application is built as whitelabel and branded for B2B clients. The brands are produced in build time and therefor any change to it requires new deployment. The frontend app is built using EmberJS framework. I personally was involved in implementation of many application features and together with my colegues we delivered branded application to production for 10+ B2B clients.
Some highlights of my contributions I am proud of:
- components for forms - I created generic components for building forms which increased our team productivity when building new pages and it also standardized how we build the forms
- Grunt -> Gulp - Originally the frontend project was built using Grunt and the build took 40 seconds when file in whitelabel was changed. For brands it could reach up to 1 minute. I refactored whole build process into Gulp and now build takes 6-8 seconds no matter if it is whitelabel or brand.
- branding architecture - together with my colleague we created concept how whitelabel is branded and later we extended it with many features. Basically now there is possible to change anything in whitelabel brand with only little effort.
It is one of the WebUI brand for Wirecard itself. It shares 90% code with the whitelabel WebUI but as addition it contains runtime branding engine which serves hundreeds of clients whose have limited customization options which are made online (it does not require new version deployment). For example clients can change logo, texts, static content, some configuration. I can say that I drived the architecture of this project. I designed how app should fetch the configuration from server, how login to multiple tenants should work, how app will brand itself after login or based on url, I designed the process how configuration can be changed. Besides design of arhitecture I was part of development team and together with my colegues we successfully delivered this product to production on time and now it serve tousands of Wirecard users.
Main technologies used: BFF - Java, Spring, Kotlin (configuration change service - batch job), ReactJS (configuration UI), plus same technologies used as for Whitelabel WebUI.
Brand ServerThis project was not in our team ownership but we used it as payout configuration provider backend app. Me together with my collegues successfully contributed to it where we developed services needed for our needs, like storing and getting the payout configuration and static content like images or pdf files. It was great experience for me because we collaborated with external (remote) team and we needed align decision process, code reviews or releases together.
Main technologies used: Java, Spring, Oracle DB
Transaction BankingAfter spending 4 years on WebUI/Payout project I took the challenge on new project as software architect. We are building totally new product (from scratch) for banking industry (I cannot tell more from business side). I am personally responsible for designing frontend solution for this product and I am also part of architecture group which takes technical decisions how the product will be developed. Since we started (1 year ago) I designed architecture of our frontend apps with code sharing (monorepo) and app build time branding with strong contract between brands (using custom Webpack loader + TypeScript). I decided to use TypeScript as a main programming language and ReactJS as a main applications framework but I am investigating options how we can better handle scaling of the development team and one of the option I am considering is to build the apps using microfrontends. We are not on production yet, but after one year we have fully working MVP.
Main technologies used: TypeScript, ReactJS, JSS, Webpack, Jest
BrandUIThis was side project where I designed and developed tool by which we were able to create whitelabel brands. It supports online changes of design (from changing SASS variables to changing static content like images), it also supports changing of multilanguage texts and it even supports importing brands which has custom JS code. The best about this tool is that it has live preview (including responsive preview) and the changes are visible immediatelly. It was sold to some clients and clients created brands by themself. We also provided this tool to our marketing department and they created design using this tool for 5 clients. The tool works only offline - it does not have any backend, it works on import/export phylosophy.
Payout mobile appI took this as another side project and as a challenge to prove to management that React Native is good technology for Payout mobile app. I created fully working concept just within 2 weeks and proved to management that RN is good choice. Then the new team was created which developed final app and delivered it to app store. I was not part of that team because I needed to continue with Payout web app but I continued as tech. consultant for that team.
Tool for estimationsThat was funny :). I received more than 100 subprojects which I needed to estimate for higher management. I was not happy with the structure of subprojects therefor I created simple tool in 2 days where together with BA we split these subprojects into more than 400 features, we categorized them and estimated every feature. It was success and now we have clear road map :).
It is possible to try that tool online: http://affinity.devfl.com
