VBA - Excel & web scraping, WordPress speed

My main areas of expertise are VBA macros (Excel, web scraping) and WordPress speed optimization, where I regularly achieve 95+ score in Google PageSpeed Insights / GTmetrix. I also develop WordPress plugins, mostly WooCommerce-related. In Excel VBA I like to work on big data sets, for example, stock market and Forex data, where code performance matters. I'm proficient in standard Excel tools: formulas, charts, graphs, pivot tables, conditional formatting, Solver, etc. VBA: - over 8 years of experience - Excel automation - web scraping - passing data between Excel, Word, text files, etc. - rearranging data structure - sending e-mails based on Excel data - operations on files and folders - UserForms - custom formulas - macro speed optimization WordPress (PHP, jQuery, JavaScript, HTML, CSS) - over 3 years of experience - website speed optimization (Google PageSpeed Insights, GTmetrix) - fixing websites, small customizations - plugin development, mostly for WooCommerce

Nothing but praise for Ryszard. He completed not only in time and budget but exceeded expectations. He refactored the script making it more concise and clear. His communication is thorough and on point. I can recommend him to anyone.
