A top 3% Upwork Senior Full Stack Developer, your project is in expert hands. You keep full ownership of everything I build. I am a full stack developer, SaaS developer, React developer, and dashboard developer in the UK. Recent full stack developer work: a SaaS platform for trades businesses with job management, quoting and role-based access, plus a B2B admin dashboard on PostgreSQL, Node.js and React that a team of 20 uses daily. As a full stack developer I own the entire stack: PostgreSQL database design, Node.js and Nest.js backend, React and Next.js frontend, REST API integration, Stripe payments and Vercel deployment. Looking to hire a full stack developer, web application developer or dashboard developer who owns the technical side end to end? Let's talk. Technical consultant. Architecture. Audit. For non-technical founders my tech stack and architecture audit with written report shows what you have, what's broken and what to build next: vendor selection, estimate review, roadmap. As a Next.js performance specialist I improve Lighthouse and Core Web Vitals: one client went from 54 to 98, page weight from 2.4 MB to 610 KB. Backend developer. Nest.js. PostgreSQL. Data pipelines. As a backend developer I build production Nest.js and Node.js APIs on PostgreSQL with TypeScript. Recent work: a Nest.js and PostgreSQL backend for a raffle SaaS platform with JWT auth, OAuth providers and a REST API layer for React. I engineered a web scraping and data aggregation engine: Nest.js cron pipelines with adapters for multiple sites, anomaly detection, stale-data cleanup and webhook alerting, thousands of records refreshed daily. On the same platform I moved 4,563 hotlinked images onto Cloudflare R2 with content-hash deduplication and three sizes per asset, cutting card weight seven times. SaaS developer. Multi-tenant. Production-ready. As a SaaS developer I delivered a multi-tenant SaaS starter on Next.js with Stripe subscriptions, PostgreSQL via Neon, role-based access, billing portal and team invites, repo transferred on handover. I led a platform rebuild from legacy PHP and WordPress to Next.js and Nest.js, 40% lift in engagement post-launch. I also take Lovable and other AI-generated apps to production: on one, 14 tables let any signed-in user read every row, so I replaced the policies across all 31, moved the role claim server-side and added tests, keeping 82% of the code. Security audit. Supabase RLS. Multi-tenant isolation. As a Supabase developer I run pre-launch security audits for SaaS founders before customer data goes live. My audits cover Supabase Row Level Security (RLS), multi-tenant isolation, PostgreSQL policy design, auth flows and exposed API keys in client code. On one platform I found RLS policies that lived only in discarded migrations, never applied to the database, the silent leak an audit catches before a breach. If you're a SaaS founder on Supabase, Next.js or PostgreSQL and aren't certain your tenant data is isolated, that's the audit I do. Database migration. Schema design. Zero data loss. As a database developer I move data between databases without losing any of it. On a recent database migration I mapped 67 tables column by column, backfilled 4.8 million rows in resumable batches, then ran row counts, checksums and sampled comparison before cutover. Twelve minutes downtime, nothing lost. Stripe. Payments. Automation. I built a Stripe internal payment interface with role-based access on Next.js: PaymentIntent flow, audit log, no card data stored. I delivered Stripe subscription billing with webhooks handling upgrades, downgrades and failed payments. I wire Stripe with Make, GoHighLevel and Google Sheets so every transaction triggers the right email and CRM tag. Dashboard developer. AI integration. Data that changes decisions. With a KendoReact commercial licence I build enterprise-grade interfaces most React developers can't replicate: advanced data grids, real-time charts, complex forms under load. My portfolio includes a real-time operations dashboard on React, Redux and WebSockets, plus a SaaS dashboard with Chart.js and scheduled PDF export. AI integration is core to my work: I wire LLM APIs (Anthropic Claude, OpenAI) into production apps for insights, content pipelines and matching, keys secured server-side. API integration. Authentication. Infrastructure. OAuth integration and API authentication: credential flows for Google, GitHub and custom providers using NextAuth and JWT. Third-party API integration and webhook handling with signature verification and idempotent writes, so retries never duplicate records. Google Tag Manager with GA4 and Meta Pixel across Next.js apps, GDPR consent included.

I design websites in Figma and build them in WordPress, Shopify and Webflow. Most of my work is around business website redesigns, CMS builds and ecommerce websites that need better structure, stronger UI/UX and a clean mobile experience. For WordPress projects, I handle the full process from Figma design through development using Elementor, Gutenberg, Bricks, Oxygen or Divi depending on the site. I also work with ACF, WooCommerce, forms, migrations, technical SEO and Core Web Vitals when the project needs them. For Shopify, I work on store design, theme customization, Liquid/front-end changes, product and collection structure, PDPs, cart flows, responsive design and ecommerce UX. I can work with an existing theme or build out a more custom design depending on the scope. For Webflow, I build CMS-driven websites with reusable components and a backend that stays easy to update after handoff. I normally start with the design and structure first. That means wireframes, page flow and Figma before development when the project calls for it. This helps us get the direction right before time is spent building. I also stay involved through responsive testing, QA, performance checks and final handoff. My main areas of work: • Website redesigns and new business websites • Figma UI/UX and developer-ready website design • WordPress design and development • Shopify ecommerce design and development • Webflow CMS websites • Ecommerce PDP, collection and mobile UX improvements • Website migrations and rebuilds • Core Web Vitals and on-page SEO setup I work mainly with ecommerce, healthcare, fitness and wellness, SaaS, professional services and B2B businesses. If you already have a site, send me the link and a little background on what you want to improve. I can usually tell you pretty quickly what I would keep, what I would change and which platform or approach makes the most sense.

I’m a Full-Stack Developer with 10+ years of experience building and improving web and mobile applications. Most of my work has been around business applications where there is more to the project than just creating a UI. I’ve worked on financial applications, ERP and accounting systems, CRM platforms, booking systems, dashboards, APIs and custom software. My main stack is React, Next.js, Node.js, Express, TypeScript and JavaScript. I also work with MongoDB, PostgreSQL, MySQL, REST APIs, GraphQL, AWS and Docker. On the mobile side, I’ve worked with Flutter as well as native iOS and Android applications. A big part of my experience is working with applications that have complex business rules. For example, I’ve worked on loan and debt management systems with payment plans and financial calculations, ERP systems covering accounting, inventory, sales, purchases and reporting, and booking platforms with payments, wallets, scheduling and notifications. I’ve also worked on existing and legacy applications where the goal was to improve the product without breaking what is already working. One example was a Windows-based CRM application that was recreated for iOS and Android, including CRM synchronization and offline-to-cloud synchronization. The client later continued working with us on the Android version and ongoing development and maintenance. Another project was a jewellery e-commerce platform where the existing system was upgraded to a more scalable architecture and connected with inventory management. The reported results were a 40% increase in site speed, 25% increase in conversions and 35% improvement in order fulfillment. I’m comfortable working on a project from the beginning, joining an existing development team, or taking over an application that needs new features, performance improvements or modernization. I also work with OpenAI and Gemini APIs when AI is actually useful for the product rather than adding AI just for the sake of it. If you have an application that needs to be built, improved or maintained, feel free to share the details. I’ll look at the existing setup and requirements first and then suggest the most practical way to approach it.

I help businesses fix, improve, and scale web applications, SaaS platforms, ecommerce systems, APIs, and CRM integrations.

If you need a reliable developer who can understand your business problem, work independently, and deliver clean practical solutions, send me a message and I’ll help you figure out the best next step.

I’m a UK-based full-stack developer with 20 years of experience building mobile apps, SaaS products, fintech platforms, and AI-enabled systems. My main stack is React Native, React, NestJS, Node.js, and .NET. I’ve also worked extensively with Stripe, PostgreSQL, Supabase, AWS, Azure, Cloudflare Workers, and production-grade API integrations. Most of my work involves taking a product from an early idea or an unstable codebase to something reliable, scalable, and ready for real users. That includes architecture, development, deployment, App Store and Google Play submissions, payment flows, third-party integrations, and production troubleshooting. A few examples of my work: Dalmore Group — Built backend systems for an investment platform processing more than 10,000 transactions per day. The platform included complex trade workflows, KYC/AML processes, AI document extraction, BullMQ queues, XState state machines, and audit-ready reporting. Gymnastrio — Developed a gym management SaaS using React, .NET Core, PostgreSQL, and Stripe Connect for class bookings, personal training, and multi-party payments. Swake — Built a customer feedback SaaS using React and NestJS, with SDKs for React Native, Ionic, and web applications. Docomi — Developed an AI customer support platform with RAG, workflow-based chatbots, semantic search, and knowledge ingestion from websites, Notion, Zendesk, SharePoint, and uploaded documents. MyDiabeticHealth — Built and launched a React Native app using Expo, Supabase, and RevenueCat on both iOS and Android. Vontrix VPN — Worked on a consumer VPN app connected to a 1,000-server WireGuard network, with subscriptions, AdMob, RevenueCat, and automated server updates. I can help with: • React Native and Expo apps • Full-stack SaaS platforms • .NET and ASP.NET Core development • React, Next.js, NestJS, and Node.js applications • Stripe, subscriptions, marketplaces, and payment flows • AI integrations, RAG systems, and LibreChat • API development and third-party integrations • App Store and Google Play submissions • Architecture reviews, performance issues, and production bugs I lead the technical direction and client communication myself. For larger builds, I work with a small senior team through my agency so we can move faster without lowering the quality of the work. Share your product idea, existing codebase, or technical problem, and I’ll give you an honest view of the best way to approach it.
