MS-DOS 1.0 was originally a clone of the then popular CP/M 86 operating system by Digital Research, called QDOS (= Quick and Dirty Operating System) by its programmer Tim Paterson. Rumour has it that MS, looking for an operating system with which they could fulfill a contract they had with IBM to provide the OS for the upcoming PC, bought the rights to QDOS for mere $50,000.

Bill Gates purchased an existing DOS program called 86-DOS written by Tim Paterson from Seattle Computer Products and modified it for use on the original IBM PC in 1983. So the answer is Paterson, not Gates.

You would have to define what you mean by DOS system.
It was first developed at Seattle Computer Products by Tim Patterson as a variant of CP/M-80 from Digital Research, but intended as an internal product for testing SCP's new 8086 CPU card for the S-100 bus. It did not run on the 8080 (or compatible) CPU needed for CP/M-80. It was called QDOS, among several other names. Microsoft licensed it from SCP, made changes and licensed the result to IBM (sold as PC-DOS) for its new 'PC' using the 8088 CPU (internally the same as the 8086), and to many other hardware manufacturers. In the later case it was sold as MS-DOS.
Microsoft bought non-exclusive rights for marketing QDOS on December 1980. On July 1981, Microsoft bought exclusive rights for 86-DOS, which was the next version of QDOS.
Bill Gates NEVER wrote a version of DOS, or any other operating system for that matter.
Bill Gates never was a good coder. Matter of opinion, he's a way better thief than code writer.
