We are Stonewell (stonewell.ai), a software development agency. We develop AI solutions and process automations (mainly back-end automation with AI, plus some front-end development). Alongside this, we’re building a new business. With this venture, we transform companies’ specialized knowledge into scalable software products that expand their portfolios. This is a fast-growing unit, currently working with scale-ups in the Netherlands. We’re hiring for two roles: Mobile App Developers If you have extensive experience developing aesthetic, high-quality native mobile apps (App Store, etc.), send me some examples along with your background. Experience integrating AI functionality as a feature is a big plus. Vibe-Coding Whizkids with a Coding Background For a variety of projects, we’re looking for multiple developers who can prototype and build MVPs for our clients. Beyond rapid prototyping, you should also have the coding skills to transform these into scalable, high-quality software products. Most projects are web-based SaaS applications with AI-first functionality integrated into the back end. If you have extensive experience with vibe-coding, SaaS development, and AI-feature integration, send me a DM with your background and some examples of your work. We’re looking forward to working together! High-quality talent only. Strong English communication skills are a must. No 9-to-5 mentality—just developers who are eager to build top-notch projects for exceptional clients. In the future, there’s also the opportunity to grow into a CTO/Lead Dev role within our ventures, offering strong career development potential.

For our agency we're looking for talented developers with experience in building AI apps (mobile), AI web-apps and AI SaaS projects. So basically full-stack AI developers. You have experience in leverarging AI/vibecoding platforms to optimize the dev cycle in order to quickly iterate towards functional products. Besides that you have a deep expertise in coding and scaling from ideation to robust technical infrastructure that's datasecure and scalable. Together with us you'll be working together on our clients to turn their ideas into strong tech that they can leverage to their clients (like mobile applications with AI functionality added to it). If you think u have what it takes in order to succesfully work together with our team in the full dev cycle (rapid prototyping + scaling up), send me a DM with your experience.

For a project of our client, we're looking urgently for a freelancer/specialist with experience in building multi-channel AI automations (Whatsapp, e-mail etc) and has MUCH experience in working with Hubspot. If u have expertise in both, please send me a DM asap, ill send over some context to u.

Our agency has been growing immensely, and because of that, we're hiring new developers again. You'll be working with us on a variety of projects for our clients, delivering the best solutions possible. It’s a diverse role with a continuous flow of interesting projects for major companies in the Netherlands. Some important details about the person we're looking for: - Experience with high-code projects from scratch (coding automations, building UIs, working with API documentation, etc.) - Experience with the no-code side of things, enabling hybrid project setups. - Experience with data parsing/scraping from the web – optional, but preferred for one of our larger projects. - You’re an individual developer. We are not looking for development agencies — just skilled developers who want to work for a cool company with cool clients. - You can communicate in English impeccably and are able to work (at least partially) during Dutch working hours. You're an all-round full-stack developer, with expertise in back-end automations and low-code tooling. We're not looking for amateurs, but for the best of the best (either you are already, or you want to become it). You’ll be heavily rewarded for it. You're helping us achieve our goals, and in return, you'll get that same level of commitment from us. So, if you feel you have what it takes to develop top-notch solutions for fast-growing companies, please reach out to me with your portfolio and a bit of context about your background.

We’re looking for a development agency or an experienced team of developers to collaborate with us on an upcoming project. While we cannot disclose the exact details yet, the project will require expertise in the following areas: → Front-end Development – SaaS-style UI, potentially built fully from scratch using modern libraries → Multi-tenant Architecture – the system will grow into a SaaS platform, so experience with scalable multi-tenant systems is essential → AI Voice Agents – the system will interact through voice in a role-playing environment → Conversational AI – advanced NLP models for dialogue management, with data access through our database and complex logic handling In general, strong back-end automation expertise is required, including traditional back-end workflows, AI-driven automation, front-end integration, and conversational AI solutions. We’re looking for a long-term partner, not beginners, but established professionals who understand what it takes to build robust, scalable, and high-quality systems for larger companies. If you believe you’re a good fit, please DM me with your website, portfolio, and background.
