I'm a systems engineer and a technical communicator with over 15 years of experience of producing technical documentation for software/hardware certification (ISO, federal, state and in some cases based on RFPs). That includes user guides, training material (written and multimedia), technical specifications (functional, software, hardware, APL), QA specifications and policies. I specialize too in content architecture and usability in apps and all related written material.
My bid wourld vary depending on the type of documents you require and whether you prefer to measure the project by deliverables, or by invested time.
Thank you.
