The most amazing...
...project I've developed was an upload web client with compression and multiple upload threads showing the upload speed to be faster than the local file copy.
Employment
Experience
- Silverlight UI to HTML5 Conversion
The project was to convert a Silverlight user interface to HTML based on Angular2+. The new UI was successfully built, more responsive, and had a modern look and feel. Additional features were also implemented.
- New UI Framework
I designed the architecture and implemented an extensible UI framework to replace an outdated web UI for the existing enterprise-scale application. A new JavaScript framework was utilized with a custom, client-side model layer reflecting the server-side API, cross-frame, and window communication for multiple display UI. The rendering was based on Knockout.js templating, and modular structure with dependency resolution.
- Multiple UI Integration
I integrated UI's for multiple applications hosted on different domains in a single unified UI. The new interface provided a unified sandbox environment, and allowed communication among different applications using cross-domain messaging.
- Upload Client
I implemented a web-client for upload application. Using browser FileSystem API, parallel HTTP requests, web-workers, and compression, the new client supported pause, resume and error recovery, showed good stability and effective speed exceeding the speed of a local file copy and the network bandwidth.
