You have a bold idea for your new product. You want people to notice it instantly. You need packaging that stands out on the shelf, feels incredible in the hand, and instantly conveys your brand’s promise. This is where I come in. I design labels and packaging that demand attention: vibrant colours, textures that feel almost tactile, and details that invite customers to pick up your product, add it to the cart and check out. Your packaging isn’t just artwork. It’s the first physical handshake with your customer. It needs to speak to them before a single word is read. And it needs to comply with FDA, UK and EU regulations, perfectly print-ready. Here’s how I make your product irresistible: • Communication that’s fast, clear, and always tailored to your needs. Tailored to your timezone. • Striking fonts, harmonious colors, and imagery that leaps off the screen, starting with the first concept and mockup. • Expert knowledge of labelling regulations, so your product is ready to ship and sell. • Custom dielines, PANTONE inks, shimmering foils, deep embossing, and tactile varnishes, so your package feels as good as it looks • Print-ready files precision-built to your supplier’s specs. Your final files are hand-crafted in the latest Adobe Illustrator and delivered as a flawless, print-ready PDF. Your label and packaging come out crisp, vivid, and touchable on the very first print run. Who Am I? With over 12 years in FMCG and cosmetic packaging design and print, including hands-on experience at three top UK print companies, I know what it takes to make your product leap from concept to shelf, turning heads and sparking sales.

Content is supposed to do a job. It should show up when buyers search, get picked up in AI-generated answers, and move the right person closer to a decision. If it’s not doing that, the problem usually isn’t the writing itself. It’s the strategy underneath it. I start with keyword research, search intent, and E-E-A-T alignment before a single word gets drafted, because that is what shapes whether a piece has a real chance to rank or just gets published and goes nowhere. Over the last 7 years I've seen the same pattern: brands invest in content consistently, performance stays flat because the structure, targeting, and intent behind the content is not aligned with how people actually search. That's the work I do. I identify what's underperforming, find the gaps competitors are quietly owning, and build content that closes them. Structured for Google, readable, positioned to surface in LLM-powered results like Perplexity and SGE. I work with SaaS companies, B2B brands, and content teams that need content driving real outcomes organic traffic, lead generation, and search authority. Not just output. You won't need to walk me through basic SEO or manage the process step by step. I take ownership and deliver content that earns its place on the page. ━━━━━━━━━━━━━━━━━━━━━━━━━━ ⟣ WHAT I DELIVER REGULARLY ⟢ ━━━━━━━━━━━━━━━━━━━━━━━━━━ • SEO blog posts built around keyword research and search intent • Long-form content designed for organic traffic growth • On-page SEO optimization (titles, meta descriptions, headers, internal linking) • Clear H1–H3 structure with strong readability and flow • Content aligned with EEAT and Google’s Helpful Content standards • Blog optimization and content updates for better ranking performance • Research-backed articles with fact-checking and real value ━━━━━━━━━━━━━━━━ ⟣ SEO & CONTENT APPROACH ⟢ ━━━━━━━━━━━━━━━━ I combine content writing with SEO strategy using tools like Ahrefs, SEMrush, and Google Analytics to: • Perform SEO keyword research and content gap analysis • Improve search engine ranking through structured content • Optimize content SEO and on-page SEO performance • Align content with user intent and conversion goals ━━━━━━━━━━━━━━━━ ⟣ WHO I WORK WITH ⟢ ━━━━━━━━━━━━━━━━ ✔ SaaS companies building organic traffic through blog content ✔ B2B brands focused on lead generation and authority ✔ Startups and agencies scaling content marketing efforts ✔ Teams that need structured, strategy-driven SEO content ✔ Personal brands that need real engagement ━━━━━━━━━━━━━━━ ⟣ TO GET STARTED ⟢ ━━━━━━━━━━━━━━━ Send me: 📌 Your topic or target keywords 📌 Your content goals (traffic, ranking, leads, etc.) 📌 Your target audience 📌 Your timeline 📌 Any references or competitors If you’re building a blog strategy, scaling SEO content, or trying to turn your content into a real growth channel, I can help you create content that actually performs.
