    Expert writer and editor

    United States - Last active: 1 day ago - Tests: 2 - Portfolio: 4

    I’m writer and editor, living in the San Francisco Bay area. My 11 years at the San Francisco Business Times made me a fast, accurate writer on many subjects, from starting a small business to complex finance reporting. I was also the newspaper's copy editor for many years. My work includes many years as a digital content producer and web editor, with a focus on financial reporting, breaking news and small business coverage. Working with writers from veteran reporters down to raw interns has given me the ability to learn to polish good writing and overhaul poor writing. My fluency in the AP Stylebook and Chicago Manual of Style makes me an excellent proofreader able to take even the rawest of copy and bring it in to compliance. I am looking for writing, proofing and editing jobs on any subject.
