Web Developer London

Web Developer London

A website should do more than look professional. It should load quickly, work on every device, support search visibility, communicate the value of a business and guide visitors towards meaningful actions. Alex Costin is a Web Developer London businesses can work with to create fast, responsive and SEO-optimized websites that support long-term growth.

Alex combines more than 17 years of website development experience with over 17 years in digital marketing. His expertise includes HTML, CSS, JavaScript, React, WordPress, Drupal, Bootstrap, custom content management systems, technical SEO, PPC, analytics, content strategy, social media, email marketing and conversion rate optimization.

Web development connected to marketing

Many websites are built separately from the marketing activities intended to promote them. This can create problems when a site is visually attractive but difficult to find, slow on mobile devices or unclear about the next step. Alex takes a broader approach by considering development, SEO, advertising, content and conversion performance together.

Before recommending a solution, he can review business goals, target audiences, competitors and the role the website needs to play. A service website may need to generate qualified enquiries, while an ecommerce website may need to improve product discovery, checkout completion and repeat sales. The technical structure should support the commercial objective.

Alex’s CV describes meeting business owners, recording their goals, carrying out market research and competitor analysis and creating detailed marketing plans. This strategic foundation helps ensure that development work solves practical business problems rather than adding unnecessary complexity.

Fast, responsive websites

Visitors expect websites to load and function smoothly across phones, tablets and desktop computers. A slow or difficult-to-use page can discourage potential customers before they understand the offer. Alex’s website focuses on fast, responsive and SEO-optimized websites, with 100/100 PageSpeed targets highlighted as part of his service proposition.

Performance improvements may involve reducing unnecessary scripts, optimizing images, improving code, simplifying page structures and reviewing hosting or content management configurations. Speed should be considered alongside accessibility, layout stability, mobile navigation and the ease with which users can complete important actions.

Responsive development ensures that content, menus, forms, images and calls to action adapt to different screen sizes. This is particularly important for businesses that receive traffic from paid advertising, social media and local search, where a large proportion of visitors may use mobile devices.

Technical SEO built into development

SEO works best when it is considered during development rather than added as an afterthought. Alex’s background as an SEO specialist allows him to examine how site architecture, page templates, internal links, content structure, metadata and performance can support organic visibility.

His CV records more than 17 years of SEO experience, including on-page audits, content strategies, competitor research, backlink development and team training. A website can be built with clear, logical structures that help search engines understand its pages and help users find the information they need.

Technical SEO reviews may identify indexation problems, broken links, duplicate content, missing metadata, weak internal linking or pages that do not reflect search intent. Resolving these issues can improve the foundation for future content and digital marketing campaigns.

Development technologies and platforms

Alex’s website describes full-stack development using HTML, CSS, JavaScript, React, WordPress and custom CMS solutions. His CV specifically highlights Drupal and Bootstrap website development, including the creation of websites designed to perform well in search engines.

The appropriate platform depends on the website’s requirements, internal skills, budget and long-term plans. WordPress may suit businesses that need a manageable content platform, while Drupal or a custom solution may be considered for more complex content structures, permissions or integrations. Front-end technologies such as HTML, CSS, JavaScript and Bootstrap help create adaptable interfaces.

Alex can help businesses assess these choices in relation to maintenance, performance, security, content publishing and marketing requirements. A platform should be practical for the people responsible for updating the website after launch.

Websites that support conversions

Attracting visitors is only the beginning. A successful website should make it easy for users to understand the offer, trust the business and complete a relevant action. Alex’s conversion rate optimization experience supports the creation of landing pages, forms, calls to action and customer journeys designed around user needs.

His website reports conversion-rate increases of more than 137% and cost-per-lead reductions of up to 79% through systematic testing and funnel optimization. These are claims published on his website and are not guaranteed outcomes for every project. Results depend on the existing website, traffic quality, market, offer, implementation and testing data.

Conversion-focused development may include simplifying navigation, improving page messaging, adding relevant proof points, reducing form friction and creating dedicated landing pages for SEO or PPC campaigns. The most effective changes should be prioritised using analytics and customer behaviour evidence.

Websites for SEO and paid campaigns

A website often serves visitors from several marketing channels. Organic search users may arrive looking for information, while paid visitors may respond to a specific advertisement and expect a matching landing page. Social media users may need stronger visual content and a clear introduction to the brand.

Alex’s experience across SEO, PPC, email marketing and social media helps create more consistent journeys between channels. His CV records Google Ads Partner experience across Search, Video, Mobile, Shopping, Display and Analytics, as well as Microsoft Advertising qualifications. This knowledge can inform landing page structure, tracking and content alignment.

His website also reports more than 2,000 first-page Google keywords, more than 100 successful projects launched and more than 60 successful websites created. These published figures indicate experience building and promoting websites for a variety of commercial objectives.

International and multilingual experience

Businesses that operate internationally need websites that reflect different languages, markets and customer expectations. Alex’s CV records campaign experience in English, French, Italian, Spanish, Russian and Chinese, with projects involving markets including Spain, Portugal, Germany, France, China, Russia and the United States.

International web development may involve multilingual content, regional landing pages, local terminology, market-specific navigation and different conversion paths. A direct translation is not always sufficient, because users may search differently or require different trust signals in each market.

Reliable project delivery

Good development requires communication, testing and quality assurance. Alex worked as Digital Operations Manager for the UK Government’s Unboxed 2022 project, overseeing digital team operations, performance monitoring, cross-functional collaboration, troubleshooting, process improvement and regular website QA checks.

This experience supports a structured approach to project delivery. Requirements can be clarified before work begins, technical issues can be investigated systematically and the finished website can be reviewed across devices, browsers, forms and key user journeys.
