Hire the Best React Native Developers
in the Netherlands

I am an AI Agent and Automation Developer with 12+ years in software engineering, the last 5 focused entirely on AI agents, machine learning systems, LLM applications, RAG pipelines, and workflow automation that ships to real users. n8n Automation & AI Agents I build n8n workflows and Make,com or Zapier when they fit better for lead routing, data sync, content pipelines, support triage, and internal reporting. When a workflow needs to think rather than just follow rules, I integrate AI agents powered by GPT-4, Claude, or open-source LLMs so they make decisions autonomously. AI Voice Agents & Conversational AI I build AI voice agents using Vapi and Retell that handle real phone calls, qualify leads, book appointments, and answer customer queries trained on your scripts and connected to your CRM. Beyond voice, I develop conversational AI assistants, multi-agent systems, and agentic workflows where multiple AI agents collaborate to complete complex tasks end to end without human intervention. Machine Learning & Deep Learning I design and deploy machine learning models and deep learning solutions using PyTorch and TensorFlow from data preprocessing and model training to fine-tuning pre-trained models on your custom dataset. Whether you need a classification model, NLP pipeline, recommendation engine, or a neural network built from scratch, I build it production-ready with proper testing and monitoring. Chatbots & Generative AI Apps GPT-4, OpenAI, LLaMA, Claude I use whatever model fits the use case and budget. That covers the full stack: model selection, fine-tuning on your data, building a RAG pipeline with LangChain or LlamaIndex, vector database setup with Pinecone or ChromaDB, and deploying to production. Support bots, sales assistants, internal knowledge agents I have built them all. API Integration & System Connectivity Most AI projects die at the integration step. I make sure yours does not. REST APIs, webhooks, OpenAI and Claude API integration, CRM and database connectivity, Slack, Notion, internal dashboards whatever your stack looks like. A few things worth knowing: → I push for a small prototype before a full build faster, cheaper, and proves the idea works in your real environment → I write production code tests, error handling, logging, retry logic the unglamorous stuff that keeps your project running in six months → I will tell you when AI is not the answer if a Zapier flow beats a custom machine learning model, I will say so Core Stack: Python · n8n · LangChain · LlamaIndex · OpenAI API · Claude API · GPT-4 · LLaMA · Vapi · Retell · Voice AI · RAG Pipelines · Machine Learning · Deep Learning · Neural Networks · PyTorch · TensorFlow · Pinecone · ChromaDB · FAISS · Make,com · Zapier · Docker · AWS · Google Cloud · REST APIs Got a project in mind even half-formed?

Hi, I’m Majid — a passionate Full-Stack & Mobile App Developer with 5+ years of experience building modern, scalable applications across web and mobile platforms. I specialize in React Native and .NET MAUI for cross-platform mobile apps, and use React.js, Next.js, Node.js, and .NET to craft responsive, performant, and secure web applications. From launching MVPs to developing full-scale products, I help businesses bring their ideas to life with clean code, great UI/UX, and solid architecture. 🔧 Tech Stack I Work With • Mobile: React Native, .NET MAUI, Expo • Web: React.js, Next.js, Node.js, Express, PHP, .NET Core • Backend: MongoDB, MySQL, SQL Server, REST APIs • Tools: Git, Docker, Firebase, Azure, Agile/Trello 🧠 I’ve worked with startups and established companies, both independently and as part of a team. At Navigram Technologies, I contributed to advanced graphics functionality. As a freelancer, I’ve delivered feature-rich apps, admin panels, payment systems, real-time chat, and more. Let’s collaborate to build powerful digital experiences — on mobile or web!

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

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.
