App developer in Weesp.

Weesp is not an ordinary commuter town. The historic fortified city on the Vecht has its own industrial past — gin, cocoa, pharmaceuticals — and today it is home to the life sciences cluster around MSD (Merck Sharp & Dohme) and Aspen Pharma, a dense population of SMEs in the Vechtstreek, an active construction and installation sector, and a lively leisure and hospitality segment around the Vecht lakes. Since 1 March 2022, Weesp has been administratively part of the Amsterdam municipality, which has strengthened access to Amsterdam's infrastructure, facilities and networks without Weesp losing its own character.

At Appfront, we build apps for life sciences, SMEs, construction and leisure that take that context into account. Strategy, design, code and release management come from one team, so advice and delivery never drift apart. Whether you work for a life sciences organisation and need a field or on-site app for inspectors, you run an SME that needs a customer or staff portal in app form, or you run a hotel by the lakes wanting booking and in-stay flows on mobile, we adapt our role to your needs.

We are vendor-independent: we build for the tools you already use, or advise on a new setup if that suits you better. Code and infrastructure sit on your own accounts, so you are never dependent on Appfront to carry on.

An app in production is more than a slick UI. We build apps that also work on a half-empty battery, on a factory floor without full Wi-Fi coverage, and with a backend update running behind the scenes. Every app includes an offline-first layer that stores data locally and synchronises it as soon as connectivity returns. For inspection rounds in a pharma facility, work orders on a construction site or in-stay workflows on a boat, that isn't a luxury; it's a requirement.

For integrations we work with APIs on top of your existing systems: ERP (SAP, Dynamics, Exact, AFAS), LIMS, eTMF, Veeva, clinical registries, planning and invoicing software, PMS and POS systems, and identity providers such as Azure AD or Okta. We either build a direct integration or lightweight middleware if your source systems aren't stable enough for direct mobile calls. For authentication we choose standards (OAuth 2, OpenID Connect, biometrics).

Everything that goes into production comes with observability: crash reporting, performance monitoring, usage analytics and backend alerting. For GDPR and EU data residency, we work as standard with EU data centres and clearly maintained processing records, and we add GxP validation awareness where the use case requires it.

An app project starts with an introductory call: half an hour to an hour in which we talk through the problem you want to solve, which systems are in place, and what expectations management, IT and field users have. The call is free and non-binding. Sometimes it turns out: this could be done with a progressive web app, or: an existing SaaS product is cheaper here. Other times: this is exactly the use case where a custom app adds real value.

If there is a suitable use case, we plan a discovery. We work out the solution at architecture and interaction level: native or cross-platform, which integrations (ERP, LIMS, eTMF, scheduling software, PMS), which data flows, which compliance requirements (GxP, GDPR, audit trail), and what the release pipeline looks like. We deliver a concrete plan with scope, timeline and budget.

This is followed by the build in sprints. At the end of each sprint, something working runs on real devices — first limited, then increasingly complete. This helps you discover early what doesn't work for the medical rep, the engineer, the receptionist or the guest. We work in your own repository, with code review, automated tests and a release process for both stores.

After go-live comes maintenance and optimisation: new iOS and Android versions, changing APIs, performance tuning, store feedback. We offer ongoing support or hand over neatly to your own team. Some clients have remained our long-term mobile partner; for others we deliver and provide support on request.
