When you work with me, you keep full ownership of everything. I am a full stack developer, SaaS developer, and dashboard developer in the UK — Top Rated Plus on Upwork, top 3% globally. I build systems that run businesses — working platforms with real users, real transactions, and business impact. As a full stack developer I own the entire stack — PostgreSQL design, Node.js and Nest.js backend, React and Next.js frontend, REST API integrations, Stripe payments, and Vercel deployment. Need a full stack developer, SaaS developer, or dashboard developer who owns the technical side — architecture, payments, integrations, deployment, security? Let's talk. My recent full stack developer work includes a SaaS platform for trades businesses — a Next.js app with job management, client records, quoting, and role-based access. I also built a B2B admin dashboard across PostgreSQL, Node.js, and React — the tool a team of 20 depends on every day. 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 — fully documented, repo transferred on handover. I led a full platform rebuild migrating a legacy PHP and WordPress stack to a modern Next.js and Nest.js architecture — 40% improvement in user engagement post-launch. Backend developer. Nest.js. PostgreSQL. As a backend developer I build production Nest.js and Node.js APIs on PostgreSQL with TypeScript end to end. My recent backend work includes a Nest.js and PostgreSQL backend for a raffle SaaS platform — secure JWT authentication, OAuth provider integration, password reset and recovery flows, and a clean REST API layer for a Next.js and React frontend. Backend work that has to be correct: every endpoint authenticated, every role enforced, every PostgreSQL query written with isolation in mind. Security audit. Supabase RLS. Multi-tenant isolation. As a full stack developer and technical consultant I run pre-launch security audits for SaaS founders — the review that must happen before real customer data goes live. My security audit work covers Supabase Row Level Security (RLS), multi-tenant isolation, PostgreSQL policy design, and authentication flows. I've audited a multi-tenant property maintenance SaaS on Supabase, reviewing RLS policies and tenant data separation. On another platform I found RLS policies that lived only in discarded migrations, never applied to the database — the silent multi-tenant data 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. Dashboard developer. Data that changes decisions. As a dashboard developer with a KendoReact commercial licence I build enterprise-grade interfaces standard React developers can't replicate — advanced data grids, real-time charts, and complex forms that perform under load. My dashboard developer portfolio includes a marketing analytics dashboard with AI insights that cut campaign review time by 60% for a British agency, and a SaaS analytics dashboard with Chart.js and PDF export that replaced a weekly manual reporting process. Integrations. Authentication. Infrastructure. OAuth integration and API authentication developer portal config — credential flows for Google, GitHub, and custom providers using NextAuth, Nest.js, and JWT. Google Tag Manager setup with GA4 and Meta Pixel across complex Next.js applications, with GTM as the management layer for non-technical teams. Transactional email wired to Resend and Brevo, plus Next.js blog and CMS setup with Sanity Studio. Stripe. Payments. Automation. Payment systems are a core part of my full stack developer work. I built a Stripe internal payment interface with role-based access on Next.js — PaymentIntent flow, full audit log, zero card data stored. I delivered Stripe payment integration with webhooks and subscription billing handling upgrades, downgrades, and failed payment recovery. I wire Stripe with Make, GoHighLevel, and Google Sheets so every transaction triggers the right email, CRM tag, and notification. Technical consultant. Architecture. Audit. I work as a technical consultant for non-technical founders. My tech stack and architecture audit with written report shows founders what they have, what's broken, and what to build next — vendor selection, architecture decisions, developer estimate review, security and multi-tenant isolation review, and a roadmap. As a Next.js performance optimization specialist I audit and improve Lighthouse and PageSpeed results — render-blocking resources, Core Web Vitals, and measurable gains for user experience and search ranking.

I'm a full-stack developer based in Manchester. I architect, build, and maintain web and mobile apps end to end — from data model and infrastructure to the interface. Most of my work is in Nuxt 4 and Vue, with Supabase and Postgres behind it (Auth, Row-Level Security, Realtime), on Vercel. I designed and built a complete platform on this stack for my own business: I planned the architecture, built the backend and the frontend, and run it in production. It handles booking, payments, a custom CMS, a live video classroom with a realtime collaborative whiteboard, and an automated pipeline that transcribes lessons and generates reports. I also built the native iOS app on top of the same backend. I also architect systems for clients — including a multi-event ticketing and payments system with automated Stripe reconciliation, and a full site build currently in progress. I've integrated Stripe and other payment processors, transactional email APIs, video, and AI for audio transcription. I build iOS apps in SwiftUI and have taken them through TestFlight and Apple's review process. For WordPress work I use Oxygen Builder and WooCommerce, usually on Cloudways. Because I run a whole stack myself, I also handle the unglamorous parts — payment reconciliation, RLS and security audits, debugging webhooks and cron jobs, and getting a site back online after it's gone down. I'm also a native English speaker with a Master's in translation, so I can handle copy and on-page SEO if a project needs it. Tell me what you're working on and I'll tell you how I'd approach it.

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.
