Freelance Job: Technical content writing

I'm looking for a content writer that has experience in writing around topics software, SaaS, IT security and peripheral technology topics but for us and for some of our clients who are also in the tech sector.

I need a tone of voice that sounds comfortable talking from a B2B perspective, not over professional but technical enough. Our audience are people who are C-Suite, Director and Senior level management and business owners.

There are about 30 - 40 pieces around 800 words each. We will brief each piece but it the tone needs to be right.

Please can you give me some examples of pieces you have written before.

Thanks
