I build full-stack SaaS apps, dashboards, APIs, and AI automation systems for businesses that need clean, reliable, production-ready software.

What I help with: • Full-stack SaaS platforms • Internal dashboards and admin panels • CRM-style tools and business operation systems • REST APIs and backend services • Authentication, roles, and secure user flows • Webhooks, payment flows, and third-party integrations • AI automation, RAG systems, and workflow automation • Support automation, email workflows, document processing, and reporting tools Relevant work I’ve built: • Logistics SaaS platform for a 3PL company with seller portal, backend workflows, file uploads, email automation, carrier investigation tracking, and case management • Warehouse operations dashboard with admin panel, employee/task tracking, live TV view, exports, and operational reporting • AI support dashboard with RAG chatbot, real-time human handoff, backend APIs, ticket escalation, and workflow tracking • SEO automation platform for multiple websites with AI content workflows, publishing support, translations, and review flow • AI website automation system that turns business ideas into structured website outputs and deployable web experiences • n8n-style feedback automation with AI classification, Airtable records, Slack alerts, and automated follow-up emails Tech stack: Frontend: React, Next.js, TypeScript, JavaScript Backend: Node.js, Express.js, Python, FastAPI Databases: PostgreSQL, MongoDB, Firebase APIs & Integrations: REST APIs, API integration, webhooks, Stripe-style payment flows AI & Automation: OpenAI API, Claude AI, Gemini, LangChain, RAG, n8n, Make, Zapier Deployment: GitHub, Docker, AWS S3, Vercel Why clients work with me: • I understand the business workflow before writing code • I can work across frontend, backend, AI, database, and integrations • I build real production systems, not just demos • I write clean, maintainable code and think about long-term use • I can take ownership of features without needing every small instruction If you need a full-stack developer for a SaaS platform, dashboard, API system, automation workflow, AI integration, or internal business tool, send me an invite and I’ll help you build it properly.

I solve business challenges with custom software and automation. Recent projects include reducing manual email handling by 90% for a Netherlands-based logistics company, reducing SEO and content-management work by 60%, and building real-time warehouse operations dashboards. As an AI automation and full-stack developer, I can build the complete solution—from the frontend and backend to databases, APIs, AI integrations, automation workflows, and deployment. Services I provide: • AI automation and workflow automation • Business process automation • Custom SaaS application development • Internal business tools • Operational dashboards and admin panels • API and third-party integrations • Full-stack web application development Primary stack: Next.js, React, Node.js, TypeScript, Python, PostgreSQL, Supabase, MongoDB, Redis, Prisma, OpenAI API, Anthropic API, Stripe, Airtable, and REST APIs. I work best with businesses that have a repetitive manual process, fragmented workflow, or SaaS product idea and need someone who can build both the software and the automation behind it. Share your current workflow, bottleneck, or product requirements, and I’ll help you identify the most practical technical approach.

Funded startups hire me to take a mobile app from plan to a revenue-generating launch on the App Store and Google Play. The last app I led as mobile developer now does $10.8M ARR with 80,000+ paying subscribers and a 5.0 rating on both stores. In 7+ years on iOS and Android, apps I've built have generated $15M+ in revenue for my clients, serve 110,000+ paying users, and hold 5.0 ratings across 10,000+ App Store and Google Play reviews. You might be shipping your MVP, rebuilding a V2 your first version outgrew, or holding an AI-built prototype that's stuck before launch. Anyway, I take it the rest of the way: architecture, build, store approval, and the payment, compliance, and edge-case work that decides whether an app survives real users. 𝗣𝗿𝗼𝗼𝗳 (𝗮𝗹𝗹 𝘃𝗲𝗿𝗶𝗳𝗶𝗮𝗯𝗹𝗲 𝗼𝗻𝗹𝗶𝗻𝗲) - PawSquad: pet care subscription app. Lead mobile developer. 80,000+ paying users, 3,300+ reviews, 5.0 on both App Store and Google Play. $10.8M ARR. - Jasomi: fintech app, built end to end. 10,000+ active users. - ConnectingKnox: local business discovery app. 193 paying businesses onboarded in month one. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 1. Blueprint. Every feature, cost, risk, and timeline on paper before any code. You know exactly what you're paying for. 2. Weekly builds. You see and test a working app every week. No black box, no "it's almost done." 3. Launch. I handle App Store review, Google Play, servers, and monitoring, so the tech side runs without you. Along the way I catch the things first builds usually miss: bad UX, subscription edge cases (failed renewals, refunds, family sharing), and compliance gaps, before they become expensive. 𝗦𝘁𝗮𝗰𝗸 * React Native, Expo, and Flutter for one codebase on both platforms; * Swift and Kotlin when native is the right call. * Node.js, Supabase, and Firebase backends. * In-app purchases and subscriptions with RevenueCat and Stripe. * Push notifications, live chat, maps and geofencing, and AI features with the Claude and OpenAI APIs. 𝗠𝗲𝘀𝘀𝗮𝗴𝗲 𝗺𝗲 𝘄𝗶𝘁𝗵 where you are now: idea, designs, AI prototype, or a live app. You'll get an honest answer on whether I'm the right fit and what to build first.

Some business need their Shopify or WooCommerce store built right the very first time. While others have one that is grown fast - and now orders are not syncing, inventory is off, or integrations are quietly failing. Some businesses want to improve their existing systems. Others are ready to use AI automation to save time and work more efficiently. No matter where you are in that journey, I can help. I am Jeroen, founder of Brightness Group in Amsterdam. For more than 18 years, I have been helping e-commerce businesses and SaaS companies build and grow their digital products. I work on Shopify and WooCommerce stores, custom Laravel applications, and AI-powered automations that solve real business problems and make day-to-day operations easier.

They want to build something from scratch, improve a system that is not working well, or find practical ways to use AI in their business. Before starting any project, I take the time to understand the business, identify the real problems, and recommend the right solution. My goal is to build something that works well today and continues to work as the business grows. I do not try to be the cheapest option. I focus on delivering results and building long-term relationships. That is why many of my clients come back for future projects.
