I have helped companies to generate thousands of dollars of sales and leads from their websites. I have worked directly with founders and CEO’s of fortune 500 companies and have helped them to grow their business online. I’m not just a web developer, but i also have a keen eye for design, and i'm happy to do all kinds of css customization as well. so, here is what i do on the regular basis: • building Woo-commerce stores tailored to your demand • adjusting premium themes to your needs with optimization for performance (fast page load) • custom WordPress / Woo-commerce website • analysis and optimizing your website for performance (fast page load) • e-mail subscription configuration • long-term website maintenance, ongoing WordPress website support, webmaster and virtual assistant • sales and landing page design • marketing automation - a/b tests, email automation • WordPress load time/speed optimization and WordPress ssl/https activation • WordPress multi-site, membership website and multilingual website. • WordPress website and server hosting migration for hosting providers like godaddy, bluehost, hostgator,s1&1, namecheap, wpengine and siteground etc however, my web development & design skills are not the only reason why clients prefer working with me. even though we may be located in different countries and discuss purely technical stuff, the success of any project hugely depends on communication. I like to talk to clients a lot, explain all aspects of what I am about to do to solve their problem. so, if you decide to work with me, I'll try to bring my a-game not only in terms of coding but in terms of communication as well.
