Choosing the Best Web Developer London can make a significant difference to your website’s performance, visibility and ability to generate enquiries. Alex Costin is a full-stack digital marketing expert and web developer with more than 17 years of experience creating fast, responsive and SEO-optimised websites for businesses in the UK and international markets.

Alex combines website development with technical SEO, content strategy, conversion optimisation, analytics and digital marketing. This integrated approach means your website is not treated as an isolated design project. Instead, it is developed as a practical business asset designed to attract visitors, provide a smooth user experience and support measurable growth.

Fast, SEO-Ready Websites

A visually attractive website is only effective when customers can find it, use it and take action. Alex creates websites with performance, accessibility, security and search visibility in mind. His work focuses on producing responsive websites that function properly across desktop, tablet and mobile devices while offering a clear experience for users and search engines.

Alex’s technical skills include HTML, CSS, JavaScript, React, Drupal, Bootstrap, WordPress and custom CMS solutions. This broad experience allows him to select an appropriate technology for each project rather than forcing every client into the same template or platform. Whether a business needs a new website, a rebuild or improvements to an existing site, the development process can be aligned with its goals, audience and budget.

Page speed is another important part of Alex’s approach. His website highlights a focus on high-performance websites, including pages capable of achieving excellent PageSpeed results. Faster pages can make it easier for visitors to browse, interact with forms and complete purchases, while also supporting a stronger foundation for SEO and paid advertising.

Development Guided by SEO

Many website projects are designed first and optimised for search later. That can create unnecessary problems, including poor site structure, duplicate content, slow templates, confusing navigation and landing pages that are difficult to improve. Alex brings technical SEO into the development process from the beginning.

With more than 17 years of SEO experience, he can review how a website is structured, how important pages are discovered and how content supports customer searches. Development decisions can therefore support crawlability, page quality, mobile usability and conversion goals. The result is a website designed to provide a stronger experience for both visitors and search engines.

Alex’s CV describes his experience conducting SEO audits, defining content strategies and creating websites that support organic growth. He also creates off-page SEO strategies and backlinks where appropriate, helping businesses connect website development with wider authority-building and marketing activity.

Experience Across Industries

Alex has worked on websites and digital campaigns for a wide range of organisations, from local businesses and start-ups to major brands and public-sector projects. His professional experience includes Oxfam, the Cardiff City Council Job Club, the UK Government’s Unboxed 2022 event and international businesses across multiple markets.

At Cardiff Jobs, he created a website to help the organisation promote vacancies more effectively. The website reportedly outperformed competitors such as Adecco and Randstad, while his broader social media work increased outreach by 10,000 percent. At Promote.Barcelona, Alex created a website, developed its SEO strategy and helped the agency reach first position on Google and Bing for its target objectives.

His earlier experience also includes creating a website and brand identity for Construction Crew after teaching himself HTML and CSS. At Worcester Nightlife, he researched the market, developed a website that reached first-page search visibility and used social channels to promote alternative nightlife options. These examples show how Alex connects technical implementation with audience research and business promotion.

More Than Website Design

Working with Alex means gaining access to a wider range of digital marketing expertise. In addition to development, he can support market research, branding, photography, graphic design, video editing, SEO, PPC, social media, email marketing, analytics, marketing automation and conversion rate optimisation.

This wider perspective can be valuable when a website needs to do more than present information. Alex can help plan landing pages for advertising campaigns, create content for organic search, improve calls to action, connect social platforms and review analytics to identify opportunities for improvement. Every part of the website can be considered in relation to the customer journey.

Alex also has experience training in-house teams. His CV includes remote and face-to-face tutorials covering SEO, social media and paid advertising. This means he can provide a complete service, collaborate with an existing developer or help your team understand how to maintain and market the website after launch.

Multilingual and International Capability

Businesses that serve different regions need websites that communicate clearly with diverse audiences. Alex has experience working across English, French, Italian, Spanish and other international markets. His background in multilingual marketing can support companies expanding beyond London or targeting customers in several countries.

International website projects can involve more than translating text. They may require market research, local search considerations, appropriate messaging and content adapted to customer behaviour. Alex’s combination of development and marketing experience helps ensure that websites are planned around the needs of each audience.
