Hire the Best Express Js Developers
in the Netherlands

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!

Hey, I'm Kashan, a full stack developer based in the Netherlands with 6+ years of experience building web apps, desktop applications, and managing cloud infrastructure. I hold a Master's degree in Business Data Analytics from TIAS School for Business and Society in the Netherlands. I've completed 33 projects on Upwork with a 100% Job Success score and Top Rated status. I work across the entire stack. On the front end, I build with React, NextJS, Angular, and VueJS. On the back end, I use NodeJS, Express, Python ,PHP, and Laravel. I'm equally comfortable spinning up a WordPress site with custom plugins as I am architecting a MERN or MEAN stack application from scratch. Beyond web development, I build cross-platform desktop apps using Electron and Tauri, and I handle the DevOps side of things too. Docker, AWS, Azure, DigitalOcean, CI/CD pipelines, Nginx, SSL, and Linux server management. If your project needs a database, I work with MongoDB, PostgreSQL, and MySQL. On the data and analytics side, I work with Python, Tableau, Tableau Data Prep, Orange, and Altair AI for data visualization, business intelligence, and data-driven decision making. I've also built several AI-powered applications using the OpenAI API, including chatbots and intelligent web tools. What makes working with me different is that you get one person who understands the full picture, from writing clean, documented code to deploying it on a properly configured server. I don't just build features; I think about architecture, performance, and long-term maintainability. I'm in the CET timezone, which works well for both European and US-based clients. I typically respond within a few hours and I'm always open to hopping on a quick call to discuss your project before we start. If you're looking for a reliable developer who can take ownership of your project end-to-end, send me a message. I'd love to hear what you're working on.

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. Thanks, Dirk-Jan
