Hire the Best Desktop Applications Developers
in the Netherlands

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.

🔹 End-to-end guidance from idea to release 🔹 Create the UI/UX from scratch or work with your provided designs (Figma, Sketch, etc.) 🔹 Native iOS & Android apps or cross platform with React Native 🔹 Successfully launched many apps to the App Store & Play Store 🔹 Transparent communication and frequent progress updates 🔹 Rapid turnaround and on-time delivery 🔹 AI integration 🔹 Web front-end development with Angular or React 🔹 Back-end development with Java (Spring), Rust or Node 🔹 Familiar with all common APIs and integrations I’ve been developing software for over 20 years, working on a wide range of projects including back-end services, hosting, containers, websites, desktop applications, APIs, and custom-built systems. I approach every job with dedication, aiming for efficient solutions that are reliable, affordable and easy to maintain.

I help teams ship faster and with fewer bugs by building scalable automated tests and detailed QA reports for web, mobile, and desktop apps. Using Playwright, Cypress, and strong API testing, I create regression and E2E test suites that improve product quality, reduce risk, and support long-term growth. I’m a Test Automation Engineer who helps teams ship high-quality products by building strong, scalable, and reliable testing systems. I test web, mobile, and desktop applications manually and through automation, and I focus on catching the issues that slow development down—before they ever reach your users. I work with Playwright, Cypress, API testing tools, regression suites, E2E flows, functional testing, and unit tests. My approach is simple: understand how your product works, break it in every smart way possible, and then build tests that make sure those issues never return. I pay close attention to details that many teams overlook—edge cases, broken UI states, slow API responses, data handling errors, and unexpected user paths. These are usually where the biggest bugs hide. Finding these problems early can save weeks of development time and prevent costly production issues later on. A strong test suite doesn’t just check functionality; it supports your entire development cycle. That’s why I build reusable and scalable automation frameworks that your team can extend even years from now. Whether you continue working with me or bring in another engineer later, the framework will stay clean, organized, and easy to maintain. Clear reporting is another part of my workflow. I deliver structured test reports, detailed bug logs, and evidence-backed findings that help your developers understand exactly what went wrong and how to reproduce it. This improves communication, reduces back-and-forth confusion, and speeds up fixes dramatically. --- ### **How My Work Helps Your Product Grow** * Faster releases through automated regression and E2E coverage * Fewer production issues because bugs are caught early, not after launch * Stronger developer confidence thanks to repeatable, reliable test suites * Clear test reports and bug logs that reduce guesswork and resolve issues quicker * Scalable frameworks your team can reuse as your product grows * Better stability for new features, which supports long-term product expansion * Higher user satisfaction due to fewer broken flows or hidden issues ### **What You Can Expect When Working With Me** * Maintainable automation frameworks built with Playwright or Cypress * Deep exploration testing that uncovers edge cases and hidden failures * Clean, structured bug reports with steps, logs, screenshots, and evidence * API, UI, and functional test coverage designed around real user behavior * A detail-focused approach that strengthens product quality from the ground up If you need someone who can think like both a tester and a developer, spot issues early, build automation that lasts, and communicate clearly through detailed reports, I’m here to help you create a stronger, safer, and more scalable product.

Reach out anytime to discuss how I can support your next project. Also I’ve been living in Java’s world long enough to make the JVM behave on command. I build stuff that runs fast, scales cleanly, and doesn’t fall apart under pressure — from Spring Boot microservices to data pipelines and API backends. I’m all about clean code, solid architecture, and squeezing every bit of performance out of the system. If your Java project needs a steady hand and a bit of attitude, I’ve got you covered.

I'm a fresh student in the field of Artificial Intelligence. I spend my free time designing and creating IoT systems with Arduino's and Raspberry Pi's. The whole process from setting up the electronics, writing the code and designing and 3D printing the enclosures. Additionally, I create desktop applications with integrated AI systems.
