I help businesses fix slow, underperforming websites and turn speed into measurable revenue. Most sites I take on are losing sales to slow load times, failed Core Web Vitals, and years of plugin and theme bloat. I strip that back and rebuild it fast, clean, and built to convert. Recent results: » Shopify store: custom development + speed optimization → $49K additional monthly revenue (42% increase) » Corporate WordPress site: migrated to headless Next.js → 67% faster load, 38% more leads » SaaS platform: performance optimization → now handles 25K+ concurrent users smoothly » Average client outcome: 35–50% revenue increase within 90 days of launch or optimization 100+ web development and optimization projects delivered. 100% Job Success on Upwork. Based in London (UK), working across UK, EU, US and global timezones. WHAT I DO WordPress Speed Optimization & Development » Core Web Vitals and PageSpeed optimization (LCP, CLS, INP) » Plugin and theme cleanup, database optimization, caching setup » Custom theme and plugin development (ACF, Gutenberg blocks) » WordPress migration with full SEO and ranking preservation » Vercel and Cloudflare CDN deployment Shopify Speed Optimization & Development Shopify store speed and Core Web Vitals optimization Liquid theme development and custom templating Conversion rate optimization (CRO) audits and fixes Custom Shopify app development and Shopify Plus customizations Checkout extensibility, Shopify Functions, metafields Klaviyo / Omnisend email and GA4 conversion tracking Headless Architecture (WordPress & Shopify) » Headless WordPress with Next.js, React and WPGraphQL » Headless Shopify storefronts (Hydrogen and custom Next.js front-ends) » Decoupled / API-first CMS integration (Contentful, Sanity, Prismic) » WordPress-to-headless migration with SEO and rankings preserved » Vercel and Cloudflare edge deployment for sub-second load times This is where my best results come from: the headless Next.js migration above delivered 67% faster load and 38% more leads.

Hey there! 👋 I'm Charlie, and I've been building websites for over a decade now (yes, I started when flip phones were still a thing). What began as a side hobby quickly turned into my passion when I realized how much I love solving problems through clean code and thoughtful design. Here's the thing – I don't just build websites, I build digital solutions that help real businesses grow. Whether you're a real estate professional, a business owner, or an entrepreneur, I get genuinely excited about bringing your vision to life. What I Actually Do (Beyond the Tech Jargon) WordPress Websites That Don't Give You Headaches I create WordPress sites that are fast, secure, and – here's the kicker – you can actually update them yourself without calling me every time you want to change a photo. I'll even teach you how (and I promise to be patient if you ask me to explain it twice). Shopify Stores That Turn Browsers Into Buyers Building an online store isn't just about making it look pretty (though mine do). It's about understanding why someone clicks "add to cart" but then abandons their purchase. I design the entire customer journey with psychology in mind, so your visitors actually become paying customers. Custom Solutions When Standard Won't Cut It Sometimes you need something that doesn't exist in a template. That's where my background in HTML, CSS, JavaScript, and React comes in handy. I can build exactly what you're imagining, even if you're not quite sure how to explain it yet. The Platforms I Work Magic On: - WordPress (my bread and butter) - Shopify (for serious e-commerce) - Wix (when you want something different) - Webflow (for the design-conscious) - Custom development (when you need something unique) Why Choose Me Over the Other 47,000 Developers on Here? I Actually Answer My Messages Seriously. I'm available 7 days a week, and I won't leave you hanging when you have a question. Good communication isn't a bonus feature – it's the foundation of every successful project. I Speak Human, Not Just Code I'll explain everything in plain English. No confusing technical terms, no making you feel silly for asking questions. If you don't understand something, that's on me to explain it better. 10+ Years = I've Seen It All Over 100 websites later, I've encountered pretty much every challenge you can imagine. That weird plugin conflict? Fixed it. The mysterious mobile bug? Squashed it. The "it was working yesterday" scenario? Been there, solved that. I Include Training (For Free) After I hand over your shiny new website, I don't just disappear. I'll walk you through how to use it, answer your follow-up questions, and make sure you feel confident managing your own content. What My Clients Say ⭐⭐⭐⭐⭐ MyThirdPlace "Charlie did a great job putting together the website for my small business. He turned my messy drafts into a professional looking product and he understood the vision behind the business very clearly. He kept me in the loop regularly about the progress of the project and any additional requirements needed on my end. As I am inexperienced with WordPress and website design, this meant explaining the functionalities to me with clarity, which he did. I intend to continue working with Charlie and am strongly recommending his services." ⭐⭐⭐⭐⭐ West of Center "Charlie was great - His work is phenomenal, as well as his customer service! He was super attentive and crushed timelines for multiple different projects. I highly recommend him as a freelancer for all your website and marketing needs, and am excited to work with him in the future." ⭐⭐⭐⭐⭐ Fans and Blowers "Charlie built a fantastic website for our business, Fans and Blowers. It's professional, easy to navigate, and truly reflects our brand. We've seen a significant increase in leads since the launch. Highly recommend!" ⭐⭐⭐⭐⭐ UnderTheStairs "I needed a WooCommerce store built on WordPress, and Charlie delivered exactly what I needed! The site is not only beautiful but also converts visitors into sales. Thanks, Charlie!" ⭐⭐⭐⭐⭐ TransformSites "Charlie created a stunning and user-friendly website for our agency, TransformSites. He was a pleasure to work with - professional, responsive, and always available to address our concerns. We couldn't be happier!" Ready to Build Something Amazing Together? Send me a message and let's talk about your project. I promise to give you straight answers, realistic timelines, and a website that makes you proud to share with the world.

100+ AI agents shipped · 10+ voice AI products · Top Rated Plus · 100% JSS. I was building conversational AI before LLMs made it easy. Not just an AI Engineer — I scope like a consultant, plan like a product manager, and ship like a full-stack AI Engineer. 5+ years in chat and voice, now LLM-native: RAG, multi-agent systems (LangGraph, MCP), production voice agents (Vapi, LiveKit, FastRTC). I architect and ship complete systems, not prototypes. ___________________________ 👥 WHO I WORK WITH 👉 Founders who need their first AI product built right the first time — not a demo that falls apart in front of real users. 👉 Startups scaling a voice agent or RAG system from MVP to real production traffic. 👉 Teams adding AI to what they already run — phone agents, document search, internal copilots — without breaking what works. ___________________________ ⭐ WHAT MAKES ME DIFFERENT ✅ Conversational AI since before LLMs 5+ years building chat and voice systems — so I know what actually breaks in production: turn-taking, escalation, latency, context. Not just how to call an API. ✅ Consultant + PM + engineer in one I scope the problem, decide what's worth building, then ship it. No three hires, no handoffs, nothing lost in translation. ✅ End-to-end ownership Working systems in production — with docs, support, and a plan to scale. Never half-built prototypes. ✅ Top Rated Plus · 100% Job Success The track record speaks for itself. ___________________________ 🛠️ WHAT I BUILD → AI Products & MVPs RAG systems, multi-agent workflows, AI copilots, and document intelligence — idea to working product, not a demo. → Voice AI & Conversational Systems Production voice agents and phone systems, from IVR to complex multi-agent voice. Vapi, LiveKit, FastRTC, Twilio. → Full-Stack AI Apps The whole product, not just the model — Next.js + FastAPI + Convex/Postgres, built to run in production. → Workflow Automation Connecting AI to the tools you already use — FlowXO, n8n, Make, Zapier — so it fits your process instead of replacing it. ___________________________ 📦 WHAT I'VE DELIVERED A few systems I've shipped to production: 1️⃣ Voice AI for Healthcare — ThriveLink (Roger) A multi-agent voice agent that replaced clunky web forms with natural conversation. 24k+ conversations handled, 35%+ of users prefer voice over typing, 80%+ return rate. (LangGraph · Vapi · Twilio · OpenAI) 2️⃣ Enterprise Knowledge RAG — Knobi A RAG platform over internal docs and wikis with hybrid search and cross-encoder re-ranking — accurate, cited answers. ~80% of routine questions deflected, 10k+ docs indexed. (LangChain · Qdrant · FastAPI · Next.js) 3️⃣ AI Legal Assistant — PanteraGPT (Antonio) A multi-agent LangGraph pipeline for contract review, clause extraction, and compliance Q&A. ~60% less manual review time, 3k+ documents processed. (LangGraph · OpenAI · Bedrock · PostgreSQL) 4️⃣ Coaching Bot Platform — Coachendo A chatbot trainer-and-loader that lets non-technical teams spin up and deploy coaching bots in minutes. Plus voice and RAG systems for Doña Justina, Shopperfix, PRMediaLabs and more. ___________________________ 🧭 HOW I WORK 1️⃣ Discovery — your problem, your users, your constraints. I tell you honestly if I'm the right fit. 2️⃣ Plan & Architecture — a clear plan, timeline, and milestones before any code. 3️⃣ Sprint Delivery — 2–4 week sprints with progress you see weekly. Working software, not status updates. 4️⃣ Launch & Support — production deployment, docs, and a support window. Optional retainer. ___________________________ ⚙️ TECH STACK AI / LLM — LangGraph, LangChain, MCP, OpenAI, Bedrock Voice AI — Vapi, LiveKit, FastRTC, Twilio Vector & Search — Qdrant, OpenSearch Backend & Product — Python, TypeScript, FastAPI, Next.js, React, Convex, MongoDB, PostgreSQL, Redis Cloud & Automation — AWS, Vercel, FlowXO, n8n, Make, Zapier ___________________________ 💬 NEXT STEP Four ways to work together — every project quoted up front, no surprise invoices. Figures are starting points: 1️⃣ Consultation · £120/hr — architecture reviews and direction before you build the wrong thing. 2️⃣ Scoped Build · £6k+/project (most common) — fixed scope, fixed quote: builds, integrations, POCs. 3️⃣ Fractional · £350/day — part-time AI engineering at a set weekly cadence. 4️⃣ Embedded · Let's talk — open to the right full-time or contract role, owning systems architecture to production. Send me your idea with a rough budget. Within 24 hours you'll get: - whether I can help (I say no to ~40% — a bad fit wastes both our time), - a rough scope and timeline, - and 2–3 clarifying questions. No sales pitch, no pressure — just a straight answer.
