Hi,
I'm new to freelancer.com, but I have over 10 years of experience in software engineering primarily with designing and developing C++ applications with Qt. I have an existing C++/Qt application that reads binary radar data and inserts it into a Sqlite database and provides plenty of options to query and view the data. Based on your project description, I could easily create a C++ application using Qt Creator (or Visual Studio) with an embedded Sqlite database. I would need more information on the communication over serial port and the type of data you wish to read, store, view, etc. Please feel free to contact me with any additional details or questions.
Sincerely,
Bryan MacRae
