I help companies ship production-ready AI and full-stack software faster: AI integrations, workflow automation, data pipelines, React/Node.js/Python apps, and cloud infrastructure built with senior engineering review. If you need more than a demo, I can help you turn an idea or internal process into a working product with clear scope, secure architecture, QA, monitoring, and a practical delivery plan. What I can build: - AI-powered web apps and internal tools - LLM integrations with OpenAI, Anthropic, or self-hosted models - AI-assisted software delivery workflows for product teams - Workflow automation and data pipelines - React / Next.js frontends and Node.js / Python backends - APIs, dashboards, admin panels, and SaaS features - Cloud deployment, CI/CD, monitoring, and production hardening Where I create the most value: - You have an AI idea but need a senior engineer to turn it into a real product - Your team wants to speed up development with AI-assisted SDLC without losing code quality - You need to integrate AI into an existing SaaS, CRM, marketplace, or internal platform - You need a fast MVP, pilot, or technical roadmap before committing to a larger build My delivery approach is pragmatic: - Quick discovery to define the business goal, users, risks, and success metrics - A clear technical plan with architecture, milestones, and trade-offs - AI-assisted implementation for speed, with senior human review for architecture, security, and critical logic - Automated QA, code review, and release practices so the result is maintainable - Production-minded deployment with monitoring, cloud infrastructure, and documentation Recent relevant work includes AI-assisted development process consulting, AI infrastructure planning, scalable React/API product development, and senior Salesforce/AppExchange code review advisory. I am a good fit if you want a reliable senior engineer who can move fast, communicate clearly, and deliver production-grade software instead of experiments.

I help founders and small teams take products from idea to launch. If you've got an idea, maybe some designs, and no one to build it, that's where I come in. I cover the whole build: the app itself, payments, admin dashboards, integrations, hosting. You'll get plain-English updates the whole way through, and if I think something in the brief could be done better, I'll say so. Over the last few years I've co-founded an AI SaaS, shipped a platform that's now in 300+ UK schools, and built an app solo for a £96m-turnover UK enterprise. Some work: 👉 Reputation Genie. AI SaaS I co-founded and built end to end. Helps businesses challenge unfair Google reviews. Next.js dashboard, queued AI analysis with Node and BullMQ, Google OAuth and Google Business Profile integration, full Stripe billing. 👉 DanceToSchool. Teaching platform now in 300+ UK schools. Full Next.js build from Adobe XD designs: admin dashboard, multi-tier Stripe subscriptions, Pipedrive CRM, AWS S3. 👉 Fuel Finder. My own iOS app, one of the first on the UK's new fuel pricing scheme. React Native and Expo on a Cloudflare Workers backend. 4.7K downloads with no paid marketing, 4.5 stars, and App Store conversion 3x the platform average. 👉 B2B assessment platform. Built end to end for a UK SaaS, now used by 1,000+ employees across several large UK organisations. Next.js on Vercel, Supabase, automated email reminders, and personalised PDF action plans generated on completion. I'm probably a good fit if: - You're a founder with an idea or designs and need the whole thing built - You've got an MVP or half-finished build that needs taking the rest of the way - You're a small team that needs someone to own features end to end - You want AI features added that actually do something useful If you're after one developer who can take your product from idea to launch and keep you in the loop the whole way, I can help you get there.

I’m a full-stack developer specialising in web and mobile applications, working across both front end and back end. I build complete, production-ready systems using React, Next.js, and Node.js, handling everything from UI and user flows through to APIs, databases, and deployment. A big part of my work involves web applications and custom platforms, including dashboards, admin panels, client portals, and job or data-driven systems. I’m comfortable owning a project end to end - planning the logic, building the architecture, and delivering something that’s clean, reliable, and easy to maintain. Alongside application development, I also work with Shopify and e-commerce projects where customisation, performance, and clarity matter. This includes theme customisation, custom features, and integrating external services, rather than just setting up templates. I also have experience working in Web3 and DeFi-adjacent projects, building interfaces and systems that interact with blockchain data and require careful handling of logic, security, and user experience. I’m detail-oriented, communicate clearly, and prefer to work closely with clients so expectations are aligned from the start. My goal is always to deliver something solid and practical that genuinely solves the problem, not just something that looks good on the surface.
