Hi there! 👋 I’m an Upwork veteran with over 10,000 hours delivered, 200+ successful projects, and $1M+ earned helping U.S. companies secure and scale their cloud and hybrid environments.

Miami, United States
Expert writing assistance for policies & procedures, safety manuals & plans, user guides, SOPs, instructional materials, whitepapers / content marketing,, and more... I am known for 100% accurate and high-quality content with quick turnaround, including projects which are complex and/or highly technical.
Thank you very much for visiting my profile. In my relatively short tenure with Upwork, I have been extremely successful, having achieved the Top-Rated Plus ranking which requires significant accomplishments on the platform. I also have and maintain a 100% Job Success Score; this comes from carefully selecting projects which I know that I can perform perfectly 100% of the time.
I owe my Upwork success in large part to my seventeen years of experience working for the world’s wealthiest company, Saudi Aramco - which is also the world's largest oil company. While at Aramco, I ran several prestigious programs within my 2,000-person department, including maintaining international accreditations. Because of my writing skills, I was the de facto technical writer for my department, responsible for creating policies, procedures, training manuals, SOPs, articles, press releases, and testing instruments.
Since departing Aramco, returning to the U.S., and joining Upwork, I have successfully assisted many clients with myriad and diverse projects, ranging from fairly straightforward tasks to highly complex and technical jobs. Some general examples are as follows:
• All manner of policies and procedures
• Safety courses / guides
• User guides / owners' manuals / installation guides (equipment, software, automotive, etc.)
• Whitepapers / blogs / website content / content marketing
• ASPICE documentation
• SOC2 documentation
• Amazon 2/6 Pagers - editing support
• E-learning content development
• Product descriptions (technical and otherwise)
... essentially professional and proficient editing of any written documentation/communication
Further, I bring an unparalleled aspect and asset to each project - a business partner possessing a PhD in English and JD (law) degree, with extensive editorial experience at a large publishing house. She provides a unique second layer of professional review to every project prior to submission, ensuring that the client receives a perfect product.
