I am an Accountant, Financial Modeller, and Automation Expert for Windows & MAC (Excel & Access, Outlook, PowerPoint) primarily using VBA, SQL, Google Sheets, Slides & Docs, and Python. I have produced hundreds of automated spreadsheets, databases, and IT solutions for clients over the years since 2005. I've been a professional Excel Financial Modeller and VBA Developer since 2005, working with numerous accountants and actuaries to produce mainly VBA automation tools and integrated financial models. I have also written a number of business plans for start-ups over the years and secured funding for them. In 2009 I produced my own Excel-based financial forecasting software (FD4Cast) which allows users to quickly build dynamic integrated financial models driven by VBA, and which got ICAEW approval as an accredited software platform. Since then I have built many dynamic, customised models for the Construction, Healthcare, FMCG, Automotive, Entertainment, and Financial sectors, but also completed many varied (non-financial) automation solutions for clients where the needs have been complex. I work well under minimal supervision and I always provide excellent support for previous projects where needs may have changed and modifications required.Big Data

If you're in search of advanced PPC campaigns, in-depth analytics or even expertise in paid and organic social, we should have a conversation. I bring to the table leadership experience from MediaCom and Zoro.co.uk, as well as hands-on roles at Wayfair and Flipdish. While my specialism lies in Google Ads, my tenure as a Facebook Business Support representative has given me a nuanced understanding of paid social. Across a range of sectors, including B2B, film, cosmetics, furniture and MRO, I've consistently delivered positive ROI via Google and Meta Ads. Specifically, one of my B2B clients, in a highly niched-down, hard to advertise in industry, saw an ROI of 12.7x, and another B2B client in the cosmetics industry saw a cost per lead of <£10, at a high volume. My technical skill set is comprehensive, featuring Python, Google Apps Script, SQL, SA360 and BigQuery, all of which enable me to automate and optimise PPC management effectively. When it comes to data, my approach is holistic. I employ Google Analytics and Google Tag Manager to ensure a complete understanding of every user touchpoint from initial visit through to conversion. Moreover, I use Google Looker Studio to transform your data into compelling stories. I'm open to new opportunities and keen to elevate your digital marketing efforts.
