Hire the Best Kotlin Developers
in the Netherlands

🔹 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.

When you hire a developer, you're not paying for code — you're paying for a working product. I make sure you get both. I'm a full-stack developer with deep expertise across backend systems, mobile apps, web development, and bot/automation engineering. Whether you need a high-performance API built in Go, a cross-platform mobile app, a polished web interface, or a Telegram/Discord bot that automates your workflow. I've built it, shipped it, and maintained it in production. What I bring to every project: • Clean, maintainable architecture (not just code that works today) • Clear communication and honest timelines (no surprises!) • A bias toward simplicity: the right tool for the job, not the trendiest one • Delivery that doesn't need a second round of fixes Tech I work with regularly: Go, Laravel, React, Flutter, Node.js, PostgreSQL, MySQL, AWS, Docker, and more. If you have a well-defined project and need someone who can own it end-to-end, let's talk.

I help startups and product teams ship production-ready web and mobile apps — on time, well-architected, and easy to hand off. Over 10 years I've gone from writing the first line of code to leading full engineering teams, including a SaaS platform on AWS that held 99.9% uptime under heavy traffic. Recent clients call me "committed to quality," "reliable," and someone who "does not fail the deadline." That's the baseline I hold myself to on every project. What I'm best at: ✔ React / Next.js frontends that are fast and maintainable ✔ Node.js + TypeScript backends and REST/GraphQL APIs ✔ React Native mobile apps (iOS & Android) ✔ AWS infrastructure — ECS, Fargate, Docker, CI/CD ✔ Real-time features: WebSockets, live dashboards, chat systems ✔ Fintech integrations: payment gateways, compliance, encryption ✔ PostgreSQL, MongoDB, Firebase I work with a small number of clients at a time so you get my full attention — not a response from a VA at 2am. If you have a project in mind, message me with a brief description and I'll tell you honestly if I'm the right fit.

With over 5 years of experience building multiple mobile apps for companies that generate 8-figures or are just starting out, and with an average rating of 4.9 stars from over 200 app reviews, our mobile apps speak for themselves.

I'm a software developer who not only knows how to code but also has a keen eye for design. If it's not pixel-perfect, it's not done. I started programming at the age of 12 when I created my first websites in middle school. I remember when the iPod Touch was first introduced in The Netherlands - I immediately knew that I had to do something with it. And when iPhoneOS 3 with the AppStore was launched, I wasted no time and downloaded Xcode right away to start learning how to develop for it. When I'm not building (web) apps, you can find me pursuing my other passions. I'm an avid runner, love to boulder, and enjoy strumming on my guitar.
