As an unrivalled website designer, Alex combines Drupal back-end with Bootstrap front-end to create perfect websites that search engines love.

At Cardiff Jobs (December 2015 – June 2018), working with the Cardiff City Council Job Club, he set up a website to help the club promote positions easier. This website beat competitors like Adecco, Randstad, and Broke Street, demonstrating his ability to build high-performing sites that dominate search results. [1]

At Promote.Barcelona (May–July 2018), he helped a local digital marketing agency develop their online presence. He created their website, SEO strategy, and trained them on using Google Ads and creating new organic and paid social network campaigns. Shortly after, they got on the 1st position on Google and Bing for all their goals. [1]

At Blue Trolley (April–July 2016), he helped a UK trolley manufacturer — the second biggest in the UK — open innovative marketing channels that helped their ecommerce efforts and increased sales by 2000% per week.

[1]

Training and Mentorship

Alex believes in empowering teams to become self-sufficient. He has conducted tutorial sessions — both remote and face-to-face — to train in-house teams on web development best practices, SEO audits, and digital marketing strategies. [1] At Autoocupacio, a public government body, he trained the in-house team on SEO, SEM, and social media, also mentoring Barcelona's city council marketing team members. [1]

At Dunster House (October 2020 – March 2021), he trained and supervised the implementation remotely of a team of 7 colleagues on SEO best practices (content and technical). [1] At Cash Finance (June–October 2019), he directed and supervised WordPress website rebuilds to increase landing page quality and trained a team of 7 agency workers face-to-face on best digital marketing practices. [1] His ability to train, guide, and lead teams ensures that websites are not only built but maintained and optimised over time.

Feeder Websites and Off-Page SEO

Alex doesn't just sell "services" — he offers and guarantees results. [1] He is able to create "feeder websites" that help off-page SEO and acquire new traffic and clients, a strategy many businesses are not aware of. [1] These feeder websites create content (off-page backlinks) on personal websites to maximise on-page SEO, strengthening the main website's search presence without risking penalties. [1]

His link-building strategies are ethical and data-driven, focusing on premium white-hat SEO that strengthens search presence. [2] He offers backlink packages ranging from 1000 to 10000 backlinks, designed to build durable authority and support AI search discovery. [2]
