    Experienced, meticulous proofreader

    United Kingdom - Last active: 22 days ago - Portfolio: 9

    I am a perfectionist English proofreader with a wealth of experience in a wide range of material, including fiction and non-fiction books, articles, web copy, and - in particular - academic papers such as theses and dissertations. I work with both native speakers, and those for whom English is their second language. I am passionate about the written word and helping to create text which is fluent, clear, and a pleasure to read. Proofreading is, by necessity, slow and meticulous work, and I never 'cut corners', get software packages to do the work for me, or speed-read scripts. Over the years, I have also acquired strong copy-editing skills; I routinely check for inconsistency, unnecessary repetition, contradiction, or shifts in style. Throughout the editing process, however,I remain sensitive at all times to the 'voice' and intention of the author. In brief: I am reliable, communicative, skilled and dedicated - and have never yet missed a deadline!

    Custom MS Access database development

    Croatia - Last active: 9 days ago - Tests: 2 - Portfolio: 6

    Twelve years of experience with Microsoft Access. Tell me exactly what is that itch you can't scratch with combined efforts of Excel, Word and Outlook. What tasks take away tremendous amounts of your time and nerves? I will create the database structure in such a way to solve your biggest problems first. My motto in database development is: No guessing! We will communicate your problems until it is crystal clear where are the bottlenecks. And remember, there's no database like custom made. What good of dozens of fancy features in e.g. cheap cloud based CRM systems, if you lack these few you need the most? Every single database I have created is unique, tailored exactly to the customer's needs. I don't use any templates, because "one size fits all" is philosophy good enough only for summer T-shirts. Your new database will fit you like a fine hand-made suit!
