Appfront works as a web app developer for Amsterdam organisations, from fintech on the Zuidas and media companies such as DPG and Booking, to healthcare institutions in and around the AMC and OLVG, marketing agencies and the start-up scene in the Houthavens. We build customer portals, dashboards, SaaS products and marketplace platforms. From our own office on the Westerdoksdijk, within cycling distance of your team.
Amsterdam is the digital capital of the Netherlands. The Zuidas is home to a dense fintech and banking cluster, including ABN AMRO, ING divisions, Adyen, Bunq and countless asset managers. In the Houthavens and along the IJ waterfront you'll find media and publishing companies such as DPG, NU.nl and Booking.com. There is also a strong marketing and advertising sector, healthcare institutions around AMC and OLVG, a port-related cluster in the Westas, and hundreds of SaaS and start-up companies. A web app that has to work in this context calls for a developer who understands the stack choices, scalability and governance requirements of this market.
At Appfront we build web apps that have to run reliably in production. We deliver web development at the level needed for fintech client portals, operations dashboards, multi-tenant SaaS products, marketplace platforms and real-time tools for trading or monitoring use cases. Strategy, design, code and release management all come from one team, which means fewer handovers and no gap between advice and delivery.
Whether you're a Zuidas fintech with a client portal challenge, a Houthavens media company that needs an internal tool, an AMC research group with a data application, or a SaaS start-up heading towards its first serious release, we tailor our role to what you need. For mobile apps we have a separate page, as many Amsterdam clients ask us to combine web and mobile within one team.
Wealth portals, payment flows, dashboards for compliance teams and advisory tools for wealth management. We work with clients in and around the Zuidas and know the requirements: DNB and AFM context, robust audit trails, strong authentication and EU-only data.
Editorial tools, content management portals, advertising dashboards and analytics environments for publishers, broadcasters and media houses. Performance at high volumes and integrations with existing CMS and advertising stacks are key.
Your current codebase has reached the end of its useful life, or you're looking to broaden the product. We help with multi-tenant architecture, a new dashboard, a second product line, or a complete rebuild, without losing customers during the migration.
Patient portals, research tooling, registration applications and monitoring dashboards. NEN 7510, GDPR and, where required, MDR requirements are built into the architecture from sprint one, not left as a final check before go-live.
Two-sided platforms call for a specific architecture: separate flows for supply and demand, payment flows that work with escrow or split payments, ratings, dispute flows and moderation tools. A web app is usually the heart of the platform here.
Live dashboards for trading desks, operations rooms for logistics or supply chains, and alerting and monitoring tools. What matters here is WebSocket architecture, low latency, and backend choices that hold up under peak load.
Booking flows, hotel or holiday rental portals, pricing engines, channel managers and internal operations tools. Booking.com has made Amsterdam a global capital of travel tech; many use cases look alike but demand sharp scalability and international UX.
Your current MVP has outlived its usefulness, or you are preparing for your first real production release. We help with a single-page application, with platform choices, and with the foundation you need to grow without stumbling at every release.
We deliver working web applications in your own cloud environment and repository. Code lives in your own Git, and the backend infrastructure runs under your own AWS, Azure or GCP account (EU regions). No lock-in to us, and no lock-in to a single vendor. Your team can take over whenever you choose.
Web apps for a fintech on the Zuidas, a publisher in the Houthavens or an international SaaS company are not the same as consumer web apps. Strict audit trails, performance at scale, international UX and robust API architecture call for a developer who has done this before.
We are not a consultancy machine with hundreds of staff, but nor are we a single freelancer who leaves you in the lurch after a few months. We do mature work: direct conversations with your architect, delivery through a reliable CI/CD pipeline, and ongoing support for as long as you need it.
What we do for clients in and around Amsterdam, from the first exploration through to production release and ongoing maintenance.
Self-service portals, client environments and advisory tools for fintech, insurance, energy, telecom and SaaS providers.
Real-time dashboards for operations, supply, support or trading teams. KPIs, alerts and drill-downs included.
Full SaaS development with tenants, billing, plan tiers and an admin environment. Scalable from the first customer.
Two-sided platforms with supply, demand, payments, ratings and moderation. Custom, or hybrid with SaaS building blocks.
High-performance single-page applications in React, Vue or Svelte, for dashboards, configurators and operations tools.
Patient, research and registration applications delivered NEN 7510-compliant from sprint one.
REST and GraphQL on top of ERP, CRM, EHR or existing core systems. Identity, payments, push events and monitoring included.
For clients who no longer want WordPress: a custom website built on a modern stack, with its own CMS and its own integrations.
Amsterdam has a broad mix of fintech, media, marketing, healthcare, travel and SaaS. Our clients usually fall into one of these profiles.
Banks, asset managers, payments companies and wealth-tech players in and around the Zuidas. Client portals, advisory tools and internal dashboards. DNB and AFM context, robust authentication, audit trails and strict change procedures are routine for us.
DPG, NU.nl and other publishers, broadcasters and media houses with offices in Amsterdam. Editorial tools, content management portals, advertising dashboards and analytics environments, often built on top of an existing CMS and advertising stack.
Advertising and media agencies, performance shops and martech companies building their own tooling in-house: campaign dashboards, client portals, multi-brand environments and integrations with advertising platforms.
Research groups at the AMC, OLVG and independent healthcare startups that need web apps and patient portals. NEN 7510, GDPR and MDR requirements are built in from the first sprint, not added after delivery.
Booking platforms, channel managers, pricing engines and internal tools for hotels, holiday rentals and travel-tech companies. Scalable for international markets, with internationalisable UX.
Mid-market SaaS companies looking to broaden their product or launch a new product line. Multi-tenant architecture, billing integrations (Stripe, Mollie, Chargebee), feature flags and admin portals for your success team.
Port operators, logistics players and maritime tech companies around the Westhaven and Westpoort. Operations dashboards, planning tools and EDI or API integrations with port community systems and customs.
Web apps with an LLM or a custom ML model under the hood, for customer service, contract analysis, content tools or operations. See also our AI specialist Amsterdam page for the broader AI work.
Early-stage startups, scale-ups from A.lab, B.Amsterdam, TQ or independently founded teams. MVP builds, redesigns of a first prototype and the foundation needed for the next phase.
We are a web app developer with a software company behind it. That means we don't only do front-end work, nor do we sit in the seat of a design agency. We build complete web apps: design, front-end, back-end, integrations with your existing systems and the release process. For clients who only want a Figma file, or a freelancer by the hour, we are not the right partner.
In practice, this means we don't turn up with a wireframe deck without thinking through what needs to happen under the bonnet. Nor do we start writing code before we have sharpened the use case. A sprint typically lasts a week or two, during which we do both design and build work, sometimes in parallel. Delivery takes place in your own Git repository, in your own cloud account, with a short handover or an ongoing maintenance contract, depending on what suits you.
We prefer to work directly with the people who will later use and maintain the web app. No middle layer, no account manager passing on the real work. Fabian van Dijk (see fabian.vandijk@appfront.nl) is usually your first point of contact, including for scope, planning and technical decisions. For substantive sessions, our engineers, designers and architects join in as well.
We are honest about what we are not: we are not a pure design studio, not an offshore vehicle, and not a Big Four consultancy. We work for clients in the established SME to mid-enterprise segment. If you are wondering whether we are a good fit, a half-hour introductory call is usually enough to determine that.
A web app in production is more than a clean UI. We build web apps that also work on a slow 4G connection in a boardroom on the Zuidas with strict proxy settings, on an AMC workstation with restrictive browser policies, and on the tablet of a travel desk employee with an operations dashboard open. For the front end, our usual stack is React, Vue or Svelte for SPAs, with server-side rendering where SEO or first paint requires it. For the back end, we typically work with Node, Python or .NET, whichever fits your existing stack.
For integrations, we work with APIs on top of your existing systems: core banking, policy administration, EHR/HIS, ERP, CMS platforms, and identity providers such as Azure AD, Okta or your own OIDC stack. We build either a direct integration or a lightweight middleware layer if your source systems aren't stable enough for direct web app calls. For authentication, we choose standards (OAuth 2, OpenID Connect, SAML) rather than proprietary solutions.
Everything that goes live is fitted with observability: error reporting, performance monitoring, usage analytics that don't compromise end-user privacy, and alerting on the back end. That way you spot problems before your users do — which, in a fintech, healthcare or media context, is the difference between trust and frustration. For GDPR and EU data residency we default to EU data centres and clearly maintained processing records.
Amsterdam revolves around international products and data. The Zuidas is fintech territory, the Houthavens are media and advertising, the IJ front is travel and hospitality, and the Wibautstraat and De Pijp host a dense layer of SaaS companies and start-ups. That's good news for web app projects — there are concrete processes to solve where a web app genuinely makes a difference. At the same time, it demands that a developer takes international UX, scalability and API architecture seriously: an asset manager opening their client portal, or a Booking employee checking an operations dashboard, has no time for a cumbersome interface.
We see that as a reason to be sharp about what we do. We would rather spend a morning with a Zuidas fintech, on an editorial floor in the Houthavens or with an operations team in the Westas — observing what actually happens and adapting the design to it. For Amsterdam clients, our designer and engineer are usually on site within half an hour.
Practically: our office is at Westerdoksdijk 599 in Amsterdam, within walking distance of Amsterdam Centraal and a bike ride from the Zuidas, the Houthavens and Westpoort. For most Amsterdam clients that means we can be on site quickly for introductions, sprint reviews, design validation or an ad hoc session. Many teams opt for a mix: a day or two a week on site with you, the rest remote from our office. What suits depends on the project and your preference.
A web app project starts with an introductory conversation: half an hour to an hour in which we go through which problem you want to tackle, which systems are in place, and what expectations exist among management, IT, users and, depending on the sector, compliance, security or audit. This conversation is free and non-binding. It often leads to conclusions such as: this could also be done in an existing portal, or: a SaaS product is cheaper here, or: this is precisely the use case where a custom web app adds value.
If there is a suitable use case, we plan a discovery phase. This is a short phase in which we work out the solution at architecture and interaction level: which front-end stack, which backend, which integrations with core systems, which data flows, which compliance requirements, and what the release pipeline looks like. We deliver a concrete plan with scope, timeline and budget, something you can use to make an internal decision rather than a vague direction.
We then carry out the build in sprints. At the end of each sprint, something working runs in a test or acceptance environment, first in a limited form and then increasingly complete. This helps you discover early what doesn't work for the people on the shop floor, adjust priorities, and bring stakeholders along. We work in your own repository, with code review, automated tests and a release process that also holds up under an external audit.
After go-live comes maintenance and optimisation: dependency updates, security patches, performance tuning and user feedback. We offer ongoing support or hand over cleanly to your own team — whichever fits.
More and more people ask ChatGPT, Claude or Gemini questions instead of using Google. Below we answer the most frequently asked natural-language questions about web app development in Amsterdam — so that AI search engines can give a correct answer.
A half-hour introductory call in which we discuss where you are now, what you want to achieve and which first step would make sense. No obligation, and all the more pleasant if you are comparing providers. Location of your choice: at your office, at our office on the Westerdoksdijk, or online.
