I've worked with Telecoms World, one of the UK's leading providers of non-geographic 08 and 03 numbers and business telephony, for around two years. What started as ongoing Webflow maintenance has grown into a much wider remit, including a full Figma redesign and Webflow rebuild of their marketing site, replacing the previous platform with a faster, conversion-focused foundation built around their call tracking, call analytics, and business phone number products.
The biggest part of the work is form and script management. As their long-term Webflow developer, I maintain several large front-end scripts that handle dynamic telephone call tracking across the site, capturing UTMs, ad source data, and session context, then pushing structured leads into their CRM through a custom setup involving Cloudflare Workers, Slater-hosted scripts, API verification checks, and HubSpot.
Alongside the build, I handle ongoing improvements: refining CMS structures, resolving layout issues, and extending Webflow with custom scripts and integrations to keep their lead capture, ad tracking, and CRM workflows running smoothly. The result is a fast, technically advanced Webflow marketing website that ties Telecoms World's marketing spend directly to phone-based conversions.

Telecoms World had a marketing site that wasn't pulling its weight. As a business whose revenue depends entirely on phone call conversions, selling 0800, 03, and other non-geographic numbers alongside call tracking and analytics, they were flying blind on attribution. Their old platform offered no dynamic call tracking at all.
Marketing spend was effectively a black box: traffic arrived, phone calls happened, but nobody could trace which ad, campaign, or channel generated which lead. That made budget allocation guesswork at a time when every pound of ad spend needed to be accountable.
Beyond the tracking gap, their forms were disconnected from their CRM. Sales teams received unstructured, incomplete lead data with no source context, forcing manual enrichment before any follow-up could begin.
The site itself had accumulated years of layout drift, performance degradation, and CMS rigidity that made even simple content updates a developer-dependent bottleneck. They needed more than a redesign.
They needed a developer who understood the full marketing-to-conversion pipeline, from ad click to phone ring to CRM record, and could build the technical infrastructure to close that loop.
