HOW I APPROACH YOUR PROJECT I don't start with “Which framework should I use?” I start with the product. What problem are we solving? Where does AI create value? What belongs in mobile versus backend? What can break at scale? For existing apps, I identify the real bottleneck before recommending a rewrite, whether it is poor architecture, performance, AI integration, technical debt, crashes or third-party API issues. For new products, I build an architecture that can evolve with users, features and AI usage.

100% Job Success · 42 AI projects shipped. I build AI voice agents and automations that run in production not demos. Vapi/Retell voice receptionists, n8n & Make workflows, and RAG systems on your own data, with clean tested code that keeps working after launch With 12+ years in software engineering and the last 5 focused on AI agents, workflow automation, and LLM applications, I build solutions that reduce manual effort, improve response times, and connect seamlessly with your existing tools. My work includes: - n8n, Make, and Zapier automations for lead routing, data sync, reporting, and support triage - AI agents with GPT-4, Claude, and open-source LLMs for smarter decision-making and task execution - RAG pipelines using LangChain and LlamaIndex with Pinecone, ChromaDB, or FAISS - AI voice agents with Vapi and Retell for calls, lead qualification, booking, and customer support - Machine learning and deep learning solutions using Python, PyTorch, and TensorFlow - API integrations with REST, webhooks, CRMs, Slack, Notion, databases, AWS, and Google Cloud I prefer to start with a small prototype so we can validate the idea quickly before scaling it into a production-ready system. I also write clean code with testing, logging, retry logic, and error handling so the solution keeps working long after launch. If you need an AI automation, voice agent, chatbot, or custom workflow built with a practical business outcome in mind, send me a message and I’ll tell you honestly whether I’m the right fit.

I build 3D product configurators and interactive web visualization tools — the kind of experience that lets customers rotate, customize, and preview a product in real time before they buy. For the past 5+ years I've worked on the visualization side of enterprise configurator software, building 3D scenes, rendering pipelines, and interactive product customization tools used by manufacturers across Europe. This is a specialty most full-stack developers don't have — combining real-time 3D rendering (Three.js, WebGL) with the full-stack skills to wire it into a working product (React, Node.js, .NET, PHP). What I can help with: *Building 3D product configurators from scratch (furniture, automotive, outdoor structures, real estate, industrial products) *Upgrading existing 3D scenes: PBR materials, realistic lighting, performance optimization, mobile/WebGL compatibility *Full-stack development around a configurator: React front ends, Node.js/.NET/PHP back ends, API and database integration *Full-stack and mobile app development (React Native) when a project calls for it Selected work: a WebGL/PHP 3D furniture configurator, an Angular/PHP/WASM industrial furniture platform, and full-stack apps spanning fintech, real estate, and e-commerce. I scope realistic phases and deliverables rather than open-ended estimates, and communicate in clear, direct updates throughout.

I spent the greater part of the last 18 years working on web and mobile app development to help businesses and entrepreneurs provide services that set them apart from their competitors. The 'do more with less' approach I take in designing solutions aims to empower clients to achieve higher levels of profitability, recapture time and resources previously consumed by inefficiency, and invest those gains in any way they see fit. Technically speaking, I primarily work with the following development stack: - HTML5, CSS3/SASS/LESS/Stylus, Twitter Bootstrap/Bulma - React, Vue, AureliaJS, Backbone, Ember - Node.js/Express.js, Laravel framework, CodeIgniter, ASP.NET, Ruby on Rails - Wordpress, Drupal, Magento - Contentful CMS, Netlify CMS - MySQL, PostgresSQL, MongoDB, FirebaseDB, DynamoDB, AzureDB - Objective C, Swift, Android - React Native, Flutter - Ionic, PhoneGap - AWS, Digital Ocean, Heroku - Webpack, Gulp, Grunt - Jasmine, Mocha, Chai, Enzyme If you are looking for a developer that's truly an expert, driven by passion, not afraid to take on a challenge, I will be there with you every step of the way then look no further as I am your guy. Thanks, Dirk-Jan

Welcome to my profile, I specialize in building production-ready applications that handle real-world complexity—from real-time data processing and multi-tenant SaaS architectures to secure payment integrations and high-traffic scalability. My experience comes from developing systems where performance, security, and reliability directly impact business operations and user trust. I’ve engineered end-to-end platforms for healthcare administration, clinic management, dating, and e-commerce, with a focus on solving deep technical challenges. This includes implementing real-time dashboards with WebSocket-driven updates, designing atomic transaction flows for financial operations, and building role-based access control for sensitive data. On the backend, I architect robust systems using Laravel, Node.js (NestJS), and PostgreSQL, with attention to query optimization, connection pooling, and background job processing. I have built: - Real-time admin dashboards with live metrics using WebSockets (SocketIO) and Highcharts - Multi-tenant SaaS platforms with isolated data, subscription billing, and automated invoicing - Secure payment pipelines with Stripe, including subscription management and PCI-compliant workflows - High-performance APIs supporting real-time chat, calendar scheduling, and inventory synchronization I implement security at every layer: JWT/OAuth 2.0 authentication, encrypted data storage, audit logging, and rate limiting. I structure applications to maintain uptime during traffic spikes, using caching strategies (Redis), queue workers, and efficient database indexing. On the frontend, I build responsive, pixel-perfect interfaces with React, Next.js, or Vue, using Tailwind CSS and component libraries like Shadcn UI. I focus on delivering fast, accessible user experiences—whether for real-time dashboards, interactive booking systems, or complex admin panels—while maintaining strict design fidelity and Core Web Vitals. My approach is product-focused and detail-oriented. I prioritize clean, maintainable code, thorough documentation, and infrastructure that scales. I’m comfortable migrating legacy systems, optimizing slow queries, and debugging production issues in high-stakes environments. If you’re looking for a developer who understands both technical implementation and business impact—and can deliver secure, scalable systems from concept to deployment—I’m ready to help. Thanks
