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.
