    I worked as a headhunter and recruiter for over a decade, in my time recruiting I estimate I have seen over 100,000 resumes and rewritten over 2,000 (over 600 of those are on Upwork, check out my reviews below!). My experience has been gained in a variety of industries, I have expertise in Construction, Pharmaceuticals, Sales & Marketing, IT, Accounts & Finance, Property, Engineering, Healthcare & Education. Each industry has its own style, and a different approach is needed for all; language modifications, tone, formatting all need to be different for each. I never use the same template, your documents will be unique to you. It makes more sense to me to complete the content and then create a format that flows nicely with that information, rather than shoehorn content into an existing template. I will take the time to understand your needs and personality, and make the document fit with those. Research suggests hiring managers spend a matter of seconds analysing a resume before making a gut decision, first impressions count. I can use my experience to re-write your resume, help you land that dream job you've been chasing. Once the resume, CV and cover letter does the job, I'm here to help you through the interview process. Having facilitated thousands of interviews in my career, I know that these can be nerve wracking, the best solution to this is practise and preparation. I have been on LinkedIn for more than a decade, I've organically grown my own network to over 10,000 and had posts reach over 1 million people. I can increase your engagement, manage your profile, grow your network, improve your profile so you appear in more searches or generally revamp the profile to keep it in line with your other professional documentation and profiles. I have recently developed my own 10 point guide to LinkedIn improvement - ask me about it!
