    I have busied my time the last ten years with projects of various types, from academic writing to blog writing, from web site development to writing web copy. Though these may seem to be on polar opposites, I entered into web development and found myself writing for websites. I have a passion for both. I have since gone on to assist companies and students and, in general, people from all walks of life who may need help with their writing projects or web development and design. I am versatile, dedicated, and experienced in these areas. I consistently strive to meet and exceed the expectations that my clients and customers have of me. I know my limitations. If there is anything I would be unable to assist you with, I won’t waste your time (or mine!). Please check out my portfolio below and reviews. Rest assured that if you do choose me for your project, I will finish it to your complete satisfaction. I am eagerly looking forward to working with you! menos
