Alex Costin is an experienced web developer and digital marketing specialist who builds responsive, accessible, secure and SEO-optimised websites for businesses in London, the UK and international markets.

With more than 17 years of experience across website development, SEO, content strategy, performance marketing and digital operations, Alex offers a broader perspective than a developer who focuses only on code. He understands that a successful website must combine technical quality with clear communication, strong user experience, effective content and commercial objectives.

Whether you need a new business website, an e-commerce platform, a website rebuild, a faster landing page or technical improvements to an existing site, Alex can create a practical solution built around your goals.

Why Choose Alex Costin?

Alex Costin combines hands-on development skills with experience in SEO, analytics, paid advertising, market research and conversion rate optimisation. This means that every website can be planned with visibility and performance in mind from the beginning, rather than trying to add SEO after the development work is complete.

His CV describes him as an experienced website designer who combines Drupal back-end development with Bootstrap front-end design to create high-performance websites that search engines can understand. Alex also works with HTML and CSS and has experience creating responsive interfaces that function across desktops, tablets and mobile devices.

Alex’s main objective is not simply to deliver a website that works. He builds websites that are fast, accessible, secure, maintainable and enjoyable to use. He tests forms, buttons, menus and interactive features before launch, helping reduce the small technical problems that can damage user trust and lead generation.

Responsive Website Development

Many customers first discover a business through a mobile device. A website therefore needs to adapt naturally to different screen sizes while remaining easy to navigate and read. Alex uses responsive front-end architecture and Bootstrap-based development to create layouts that work consistently across modern devices and browsers.

A responsive website should do more than shrink desktop content. It should provide clear navigation, readable typography, appropriately sized buttons, fast-loading images and a straightforward journey towards an enquiry, purchase or booking. Alex balances visual design with functionality so that the website feels professional while remaining practical for real users.

His experience in creative design, photography and content production also helps him understand how visuals and messaging affect the overall digital experience. The result can be a website that reflects the brand accurately and communicates its value within seconds.

Drupal, Bootstrap and Custom Websites

Alex has master-level experience with Drupal and Bootstrap, as well as strong HTML and CSS skills. Drupal can provide a flexible foundation for businesses that need structured content, custom functionality, editorial control or a website capable of expanding over time. Bootstrap can support a consistent and responsive front-end experience when implemented carefully.

Alex can create custom themes, components and page structures designed around the needs of each organisation. Instead of forcing a business into an unsuitable template, he can plan a website architecture that supports its services, products, content and marketing campaigns.

His CV records website development work for businesses and organisations in the UK and Europe. His experience includes creating websites for marketing purposes, rebuilding WordPress websites, developing online platforms and supporting teams responsible for ongoing digital improvements.

Fast and SEO-Ready Websites

Website speed affects usability, engagement and the ability of a page to perform in search results. Alex’s website describes his work creating “Perfect Websites” with strong PageSpeed performance and maximum landing-page quality. His development approach is closely connected to technical SEO, helping businesses avoid common problems such as slow pages, poor mobile experiences and unclear site structures.

SEO-aware development may include clean HTML, logical headings, crawlable navigation, descriptive metadata, accessible content, optimised images, responsive layouts and effective internal linking. These elements help search engines interpret a website while making it easier for visitors to find information and complete actions.

Alex also understands the importance of testing and continuous improvement. After launch, performance data, user behaviour and conversion rates can reveal where visitors encounter friction. These insights can then be used to refine page layouts, forms, calls to action and content.

Web Development Combined with SEO

Alex’s combination of web development and SEO is particularly valuable for businesses that want their website to attract organic traffic. His CV records more than 17 years of experience conducting SEO audits, defining content strategies and working with teams to build search-focused content.

He can review an existing site to identify technical barriers and opportunities for improvement. This may involve assessing indexing, page structure, on-page elements, internal links, website speed and landing-page quality. By addressing development and SEO together, businesses can create pages that are easier for search engines to discover and more persuasive for potential customers.

Alex also has experience developing feeder websites that can support off-page SEO and introduce new sources of traffic. Any supporting website strategy should be carefully planned, relevant and aligned with quality standards. The aim is to build a useful digital presence rather than create unnecessary websites with no genuine value.

His wider professional background includes serving as Digital Operations Manager for Unboxed 2022, a UK Government initiative. In that position, he oversaw digital team operations, monitored performance, collaborated with content, social, creative and photography teams, supported quality assurance and helped improve digital processes.

Alex’s CV also highlights experience rebuilding WordPress websites, improving landing-page quality, training internal teams and creating digital platforms for local and international organisations. This range of work gives him a strong understanding of how websites need to support marketing teams, business owners and everyday customers.

A Reliable Web Development Process

Alex begins by understanding the business, audience, objectives and technical requirements. He then plans the website structure and user journey before developing the required components. Testing is carried out to identify errors and confirm that the website works correctly across devices.
