I'm a full-stack software developer and technical problem-solver who helps businesses build, fix, deploy, and scale their web and mobile applications — quickly, reliably, and with clear communication throughout the process. 🔧 Web Development & CMS I build and maintain custom web applications using React, Node.js, Golang, and PostgreSQL, and I'm equally comfortable working inside WordPress environments — Elementor Pro customization, WooCommerce setup, theme/plugin troubleshooting, CSS/JS fixes, page-speed optimization, and WordPress SEO. Whether it's a small fix like a broken login flow or guest access error, or a full redesign, I treat every task — big or small — with the same level of care because I know first impressions on trial tasks matter. 🔌 Integrations, Portals & APIs I regularly build custom portals and internal tools that connect to CRMs (Google Sheets, databases), automate data syncing, and eliminate manual data entry. I have experience with REST APIs, webhook-based automation, and building admin dashboards that "just work" without a client babysitting them. ⚙️ DevOps & Server Management On the infrastructure side, I manage Linux servers, configure Nginx, deploy Dockerized applications on AWS EC2 and VPS platforms like Coolify, and resolve production performance issues. I've worked on real-world problems like runaway RPC retry storms causing high CPU usage, implementing circuit breakers, exponential backoff with jitter, request cancellation (AbortController), and centralized health-state management — the kind of deep debugging that goes beyond "restart the server and hope." 📱 Mobile App Development I build cross-platform mobile apps with React Native, including AI-integrated SaaS applications, and I support Android developers with Android Studio environment configuration, emulator setup/troubleshooting, and full Google Play Store publishing — compliance checks, technical requirements, and submission walkthroughs included. 🤖 AI-Assisted Development & Automation I actively use AI coding tools (ChatGPT, Claude, Codex) to accelerate development without sacrificing code quality — but I always take full ownership of understanding, testing, integrating, and documenting whatever is delivered. I've also worked on MCP (Model Context Protocol) server builds and AI memory/retrieval systems that unify scattered conversation history into a searchable, queryable knowledge base. Why work with me: Responsive communicator across time zones (I regularly work with US, EU, and Middle East clients) Transparent about scope, timelines, and technical limitations — no overpromising Comfortable with both fixed-price trial tasks and long-term hourly engagements Deliver clean, documented, production-ready code — not just something that "works on my machine" Experience managing freelance teams, so I understand both sides of the client-freelancer relationship If you need something fixed fast, built from scratch, deployed properly, or maintained long-term — let's talk about your project and how I can help you get it done right the first time. Suggested skill tags to add: React, Node.js, PHP, WordPress, Elementor, WooCommerce, MySQL, PostgreSQL, Golang, React Native, Android Studio, Docker, AWS EC2, Nginx, API Integration, AI App Development, Google Play Store Publishing, DevOps, Circuit Breaker Patterns, Performance Optimization

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.

Have you ever wondered why your brand doesn’t show up in ChatGPT’s answers, even when you rank well on Google? That’s because ChatGPT and similar AI engines don’t use traditional ranking signals. They rely on context, authority, and data structure. Most websites simply aren’t optimized to be found, interpreted, and referenced by these models. This is where AI SEO strategies such as GEO, Generative Search Optimization (GSO). As a ChatGPT Ranking Expert, I specialize in helping businesses gain visibility within generative ecosystems like ChatGPT, Claude, Gemini, and Perplexity. My expertise in AI SEO, GEO, and Generative Search Optimization (GSO) helps ensure your content becomes a part of AI-generated answers, not left behind in static search results. My ChatGPT Ranking Process Includes: ✔︎ Auditing how ChatGPT perceives and references your website’s content. ✔︎ Creating AI-friendly content frameworks that increase the likelihood of being cited in AI outputs. ✔︎ Optimizing for LLM-based ranking signals, including semantic relevance and contextual clarity. ✔︎ Tracking visibility and refining strategy based on generative response patterns. In today’s AI-led search environment, I help your business become part of the conversation, not just another search result.
