Hello. I am interested in this project. I have gone through document and I am confident that I can do it. All we need is a perfect reliable solution which will ensure that data files are compressed correctly and uploaded successfully.

Brief Info About Me I am a "Full-Time" Individual freelancer having 8.5+ years expertise over MS Technologies(C#). Apart from having relevant technical skills, I have good analytic skills and strong grasping power. I have 3~ years of experience of working as a full time freelancer and in that span I have worked over various Windows & Web Project ranging over various domains in different sub technologies. Please have a look over my profile to gain trust on me and my work In my opinion having a verbal discussion fetches far good results then textual chat? If you also feel so then Can we discuss things over call?

Hi. I'm a programmer from Russia with strong skills in Python. You can see the full list of my skills on my profile page. I have good experience in developing applications using databases and SQL queries. Mostly I worked with SQLite, but I'm also familiar with MySQL. I'm good with version control systems, I worked with Git and Bazaar, but I'm able to learn other systems as well. My knowledge in this field includes simple actions like staging changes, commiting them to a local repository, pushing them to a remote one, merging changes, branching, and more complex actions like resolving the conflicts etc. I can work up to 40 hours a week and I'm looking forward to long-term work, few months are also good for me. If you're interested, feel free to contact me. All the best, Sergey.

Dzień dobry Thanks for this interesting project. It is very challenging but familiar project. I would be honored to help friendly Poland. Here is my proposal. Client application will generate one time 256 bit key. After that it will adjust file for supplied XSD Schema. Then it will calculate SHA-256 for each file, then compress with tar and BZip2 and divide files by 60 MB. After that files will be encrypted with supplied cryptography. Also we will sign metadata according XAdES BES algorithms. All functions will be working and all exceptions and bad requests will be handled. A main language of program will be either C++ or C# or Python. It is up to you but I recommend C++ for working with encryption also it is cross-platform and performance effective. Estimated time is 25 working hours. Libraries needed: Tar, Cryptography (you mentioned supplied cryptography algorithm. otherwise there are some trusted libraries to use) and XAdES-BES As for me, I am a veteran software developer working with multiple government organizations in Georgia, Kazakhstan, Azerbaijan etc with over 10 years experience in C#, C++ and Python programming. Please do not hesitate to contact with questions, you will be answered ASAP. I look forward to work with you. Thanks for your attention Archil

Hi, Wow, what a great job at writing a clear and detailed specification for this job. Good work! And it has inspired me to bid on the project. As I have worked in the public sector in the past, I can understand the thoroughness of the work as well as the efforts into an upfront specification. I also have 10 years of C# under the belt, making me a very good candidate with this job. I strongly believe I can deliver the work in 40hrs. In the hopes that we can collaborate on this job, Louis-Philippe Carignan
