Recommendation for Tech Blogging Platforms

I am a senior developer and I am interested in doing some tech blogging. I would like to get some feedback on what blogging platform would be ideal for tech blogging.

The topics could range from a variety of areas in computer science and mathematics including OS internals, security, programming, algorithms, statistics, calculus etc. My target is a technical audience interested in learning.

I would definitely like to spend more time on content and not have to deal with blogging infrastructure. I would like a platform where dealing with mathematical symbols and highlighting code is not tedious. Finally, I would like to reach out to a wide variety of folks including developers, ops, technical managers etc.

I am aware of github and medium but I am not sure if there are better platforms out there that will meet my needs.
