MARKEM Corp. San Diego, CA Jan 2003 – Feb 2008
Software Engineer
Assumed full ownership and responsibility to design, develop, implement, test and maintain application software on WinForms platform to support SmartLase® laser coder embedded system:
Data Movement utility. This application decompresses data files received from user email, creates files that correspond to files on a user’s workstation, saves and organizes the files into disk based flat file database, and uses the flat file database to populate a relational database containing over 40 tables. Used a hash algorithm to derive folder names to ensure that no duplicate data file is stored. Developed using C# on .NET, SQL Server as database and embedded SQL statements to interact with database. Programming techniques involved data decompression, cryptographic hash calculation, raw byte stream and character stream manipulation, and data access with ADO.NET.
File Transfer utility. This application works like Windows Explorer, which performs managem...
