Yi Lik Tsang

Full stack software developer with 10 years of experience, specialised in web mapping applications. I have extensive knowledge in spatial software design & development, spatial infrastructure design, deployment & configuration, and integration of spatial system into broader non-spatial systems. With an academic background in geomatics engineering and computer science, I have always been technically and conceptually very strong in both spatial and software engineering principles. For me, the core principles in achieving a successful outcome for system development are to understand the business of the systems, engage the users, and design to maximize usability. In the recent years, I have been designing and developing applications with modern web technologies including RESTful service oriented architecture, AngularJS, Bootstrap and NodeJS. My skills include: • Web mapping development using HTML5, CSS, ESRI JavaScript API, LeafletJS • RESTful web service using C# ASP.NET Web API • ArcGIS Desktop / ArcGIS Server / ArcSDE • ArcObjects development using C# .Net, VB6 • COTS Products: Geocortex Essentials / Dekho / MoxiMedia IMF • Advanced python scripting / geoprocessing model • OpenGIS: MapServer / GeoServer / GDAL / MapWindows / GeoKettle ETL • RDBMS: SQL Server / Oracle • Web Server: IIS, Apache, Tomcat • Reporting: SQL Server Reporting Services, Crystal Report
