I'm a new freelancer, so allow me to introduce myself. My name is Mark Heindl. I'm an American who moved to Sydney in June 2014. I've worked in the IT industry for 30 years, most recently developing intranet websites and managing a data warehouse and associated interfaces for a Capital Markets company (SunTrust Robinson Humphrey) in the southeastern United States. I have over a decade working with C# .NET and, due to my past data warehouse responsibilities, have extensive experience processing .csv files (and data in other formats) for consumption by other parties. In fact, one of my recent projects was not unlike this one, where the goal was to consume a file containing general ledger data and create a new output file in the format required by the General Ledger application.
Thank you in advance for considering me for your project. If you have any questions, please feel free to contact me.
