A law firm was spending on Google Ads with no enquiries to show for it. An audit found the cause: 88% of the weekly budget was going to Display banner placements instead of search, and the site had no conversion tracking installed at all — so nothing was measuring the difference. I installed GA4 and Tag Manager with a verified conversion event on the lead form, rebuilt the XML sitemap (it had listed a single URL), and replaced the campaign with a dedicated Search-only build using geo-targeting and phrase-match keywords. Within 30 days the account produced 4 tracked enquiries at a $58.43 cost per lead, a 12.12% conversion rate and a 32.35% click-through rate - every lead traceable to the keyword and network that produced it. The client's own goal was never cheap leads, it was a stable, knowable cost per enquiry he could make business decisions with.

The client had an efficient process on paper. He recorded each customer consultation, put the transcript through ChatGPT, and got a proposal back. The trouble was that it still read like a contractor's quotation, and he was losing hours to tweaking wording and formatting instead of visiting the next customer. The problem was not getting AI to write. It was getting AI to write for a designed page instead of producing a generic document that then has to be forced into one. I built a modular proposal engine. His designer keeps a library of finished A4 pages, one per product, and the engine writes the words for each one to that page's exact length. A generate, count and correct loop asks the model for the page, counts the words, and asks again if it lands outside tolerance, so the copy never overruns the box it was designed for. Every page is personalised from the actual conversation, naming the materials, the boundaries and the details the customer mentioned. The whole thing is mobile

Sourced and delivered 40 net-new decision-maker leads (Founders, MDs, CEOs) at independent Australian PR agencies across Sydney, Brisbane and Victoria. Every contact carried a verified work email (under 5% bounce), plus direct phone and LinkedIn where available. The full list was deduplicated against the client's existing CRM, and global networks, subsidiaries and non-PR firms were filtered out — so the client received only genuinely new, independent, import-ready leads, in their exact column format, with lead generation, b2b leads, data research, apollo, list building, email verification, crm, excel, australia, public relations duplicates flagged for full transparency.

Full-Stack TypeScript Developer for PWA Completion

Excellent developer and a pleasure to work with. He handled the project professionally, communicated clearly, investigated issues carefully, and completed the agreed work with attention to both the Arabic and English interfaces. He was also responsive during testing and provided clear explanations throughout the handover. I would be happy to continue working with him on the next phase.
