I help founders and teams build and ship reliable production ready apps quickly. Most projects I work on don’t start from scratch they’re already in progress, but stuck. Maybe the MVP works but feels fragile, the code is messy, or you’re not confident putting real users on it yet. That’s where I come in. I focus on moving things forward fast, while making sure what we build is stable, maintainable, and ready for real use not just demos. With 6+ years across startups, agencies, and public sector teams, I’m comfortable jumping in at any stage and bringing structure, clarity, and momentum. What you can expect working with me: • Fast turnaround without cutting corners • Clear communication and consistent progress • Clean, maintainable code that won’t cause problems later • Thoughtful UX that actually improves usability • A clear path from MVP → real product I work across both AI driven builds and traditional full stack development, so whether you’re starting from an idea, an AI generated prototype, or an existing app, I can help you move forward with confidence. If you need to build or ship something quickly and want it done properly feel free to reach out. Happy to take a look and point you in the right direction.

I help businesses build clean, modern, high-performing websites using Shopify, WordPress, Webflow, Wix, Squarespace, BigCommerce, and Framer with practical AI workflows and automation added where they can save time, capture leads, and improve customer experience. Most clients come to me when their website looks outdated, loads slowly, does not convert well, or is not connected properly with the tools they use every day. I focus on fixing the structure first: layout, speed, mobile experience, user flow, SEO basics, and conversion points. After that, I add automation or AI only where it makes sense for the business. My core services include: Custom CMS website design and development Shopify store setup, customization, and conversion improvements WordPress websites using Elementor, WooCommerce, ACF, and custom code Webflow websites, landing pages, CMS collections, and responsive builds Framer landing pages and modern marketing websites Wix, Squarespace, and BigCommerce website builds and redesigns AI chatbot setup for lead capture, customer support, and FAQs AI workflow automation using Zapier, Make, APIs, and custom integrations Fast MVP builds using tools like Lovable for testing new ideas quickly I work best with business owners, startups, agencies, consultants, eCommerce brands, and service-based companies that need more than just a nice-looking website. My goal is to build websites that are easy to manage, fast on mobile, clear for users, and designed around real business outcomes. What makes my work different is that I combine CMS development, UX thinking, SEO-friendly structure, and AI automation in one workflow. That means fewer people involved, faster execution, and a website that is built with both design and function in mind. I keep the process practical and clear. No overengineering. No unnecessary complexity. Just clean websites, smooth user experiences, and smart systems that help your business run better. Send me your website or describe what you want to build, and I’ll share a clear step-by-step plan or a few practical improvements you can use right away.

I build production AI and SaaS products end-to-end for founders. Co-founded my own AI SaaS, shipped a Next.js platform to 300+ UK schools, and solo built a mobile app for a £96m-turnover UK enterprise. 👉 Reputation Genie - Co-founded and built end to end. AI-powered SaaS that helps businesses challenge unfair Google reviews. Next.js dashboard, Node and BullMQ for queued AI analysis, Google OAuth and GBP API integration, and full Stripe billing. 👉 DanceToSchool - Teaching platform now used by 300+ UK schools. I led the full Next.js build from Adobe XD designs: admin dashboard, multi-tier Stripe subscriptions, Pipedrive CRM integration, AWS S3. 👉 B2B assessment platform - Built end to end for a UK SaaS, with 1,000+ employees using it across several large UK organisations. Next.js on Vercel and Supabase, with email reminders and personalised PDF action plans generated on completion. 👉 Mobile app for a £96m-turnover UK enterprise - Client guide app built solo for executive visits to their South Africa offices. Location-based recommendations, venue information, and push notifications for live alerts. Live on the App Store. 👉 Fuel Finder - Personal project, one of the first iOS apps on the UK's new fuel pricing scheme. React Native and Expo on a Cloudflare Workers backend. 4.7K downloads with zero paid marketing, 7.56% App Store conversion (3x platform average), 4.5 stars. What I'm best at: Shipping production web and mobile apps end to end, solo or in a small team. I've co-founded a SaaS, shipped client apps to UK enterprises, and built my own products solo, so I know what separates a prototype from a product that holds up. Comfortable across the full stack: payment flows, OAuth, queue processing, edge and VPS deployed backends. How I work: I take the time to figure out what you actually need, not just what you've written in the brief. I'll ask questions when they're worth asking, and I'll tell you if I think there's a better way. Regular async updates while we're building. The projects I enjoy most are the ones where we're figuring out the product together, not just executing a brief. If you're a founder or small team building something real, I'd love to chat.
