Hire the Best Google Apps Script Freelancers
in the United Kingdom

When you work with me, you keep full ownership of everything I build. A top 3% Upwork developer — and your site is in expert hands. I am a full stack developer, SaaS developer, and dashboard developer in the UK. 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 end to end? 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 — and a B2B admin dashboard on PostgreSQL, Node.js, and React that a team of 20 depends on every day. 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, developer estimate review, security review, and a roadmap. As a Next.js performance specialist I improve Lighthouse and Core Web Vitals — measurable gains for users and search ranking. 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 platform rebuild from legacy PHP and WordPress to a modern Next.js and Nest.js architecture — 40% lift in user engagement post-launch. I also build multilingual B2B platforms — Next.js with Sanity CMS, localised content and routing, editorial workflows non-technical teams actually use. Backend developer. Nest.js. PostgreSQL. Data pipelines. As a backend developer I build production Nest.js and Node.js APIs on PostgreSQL with TypeScript end to end. Recent backend work: a Nest.js and PostgreSQL backend for a raffle SaaS platform — JWT authentication, OAuth providers, password recovery, and a clean REST API layer for a Next.js and React frontend. I also engineered a web scraping and data aggregation engine: Nest.js cron pipelines with adapters for multiple third-party sites, anomaly detection, stale-data cleanup, and webhook alerting — thousands of records refreshed daily on Railway, Prisma, and Neon. Every endpoint authenticated, every role enforced, every query isolation-aware. Security audit. Supabase RLS. Multi-tenant isolation. As a technical consultant I run pre-launch security audits for SaaS founders — the review that must happen before real customer data goes live. My audits cover Supabase Row Level Security (RLS), multi-tenant isolation, PostgreSQL policy design, authentication flows, and exposed API keys in client code. I've audited a multi-tenant property maintenance SaaS on Supabase, and on another platform found RLS policies that lived only in discarded migrations, never applied to the database — the silent 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. AI features. 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, complex forms under load. My 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 weekly manual reporting. I integrate LLM APIs (Anthropic Claude, OpenAI) into production apps — AI insights, content pipelines, and matching features, keys secured server-side. Integrations. Authentication. Infrastructure. OAuth integration and API authentication — credential flows for Google, GitHub, and custom providers using NextAuth, Nest.js, and JWT. Google Tag Manager with GA4 and Meta Pixel across complex Next.js apps, GDPR cookie consent and Consent Mode included. Transactional email on Resend and Brevo, plus Next.js blog and CMS setup with Sanity Studio. Stripe. Payments. Automation. 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 subscription billing with webhooks 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.
