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
