Project details

You will get a fully custom Chrome extension built specifically for your needs, whether it's for your SaaS product, internal tool, startup idea, or workflow.

I don’t use templates or pre-built scripts. Every extension is developed from scratch based on your exact requirements, with clean architecture and real-world scalability in mind.

I’ve built numerous production-level chrome extensions, so I understand how to create extensions that actually work reliably & get approved in the Chrome Web Store.

Whether you need to integrate APIs, enhance an existing platform, build a custom UI, or create complex logic inside the browser, I can deliver a solution that fits your use case.

The result is a fast, stable, and maintainable Chrome extension that’s ready to use or launch.

About David

Sheffield, United Kingdom - 6:46 am local time
I’m a Full-Stack Developer specializing in building production-ready AI SaaS products, intelligent web & mobile applications, and cross-platform tools that real users love.

I take ownership from idea to launch, delivering fast, scalable systems with clean architecture, minimal maintenance, and excellent user experience for non-technical teams.

Recent production examples:

BallCourt AI - An advanced AI Chief of Staff platform
Built end-to-end: Next.js 15 dashboard with real-time attention surfaces, React Native mobile app (Expo) with offline support and voice features, Chrome extension for Gmail & universal page intelligence, and a FastAPI backend featuring a physics-based obligation engine + Bayesian modelling. The system connects Gmail, Calendar, Slack and more to auto-surface priorities and draft context-aware communication.

QuoteLab IO - Embeddable intelligent booking & quoting engine for service businesses
Full SaaS build including Next.js 15 App Router dashboard, lightweight one-line Shadow DOM widget, multi-dimensional pricing engine with conditional logic, and PostgreSQL + Drizzle backend with Stripe integration.

I also regularly create custom Chrome extensions, WordPress plugins, embeddable widgets, and complex AI-powered workflows and manage a large portfolio of enterpise apps and platforms.

Technical strengths:

- Frontend: Next.js (App Router + RSC), React, React Native (Expo), TypeScript, Tailwind
- Backend: FastAPI, Flask, Python, PostgreSQL, Drizzle ORM, Celery + Redis
- Browser/Integrations: Chrome Extensions, Shadow DOM embeds, API-first architecture
- AI focus: Context-aware agents, intelligent workflows, real-time features, and practical AI integrations that actually deliver value in production

If you're looking for a developer who builds robust, high-performance systems that feel effortless to use while handling real traffic, payments, and scale, I'm happy to discuss your project.
