Real Results, Not Just Likes

While many social media managers focus on vanity metrics, Alex prioritizes business outcomes. His work with Away Days saw weekly leads jump from ~20 to ~600 through integrated social and SEO campaigns. At Oxfam, a single day per week of his social and e-commerce strategy drove a 500% increase in online sales. For Blue Trolley, his multi-channel approach helped boost weekly ecommerce sales by 2000%.

These aren’t outliers—they’re the standard. Alex’s campaigns are built on data, testing, and iteration, ensuring every pound spent delivers maximum return. He doesn’t just post content; he engineers growth systems that compound over time.

Full-Stack Expertise for Integrated Campaigns

One of Alex’s biggest advantages is his ability to connect social media with other critical marketing functions. As a technical SEO specialist, he ensures social content supports organic search visibility. As a web developer, he builds landing pages that convert social traffic into leads. As a graphic designer and video editor, he creates thumb-stopping visuals tailored to each platform’s algorithm.

This holistic approach means clients get more than a social media manager—they get a growth partner who can align social efforts with website performance, paid ads, email funnels, and brand messaging for unified impact.
