Apps & custom

The app your customers see. The system your team uses.

B2B and B2C, web app or portal, standard platform or fully bespoke. I design and build applications that serve your customers and let your own people work faster — choosing the platform that suits your situation, not my preference.

See the Client Portal

Every business has a process that fits nowhere.

A workflow that lives in someone's head. A spreadsheet held together with hope. An integration that never quite works. A portal your customers expect but that does not exist. That is not a limitation — it is precisely the work where software pays for itself.

What I build

Six kinds of solution

The technology differs, the approach does not: understand the process first, build second. Every delivery goes through the same quality and security steps.

B2B Portals

B2B applications

Client portals, dealer and supplier environments, quote and contract flows. Software that lets your business relations serve themselves and stops your team hunting through attachments.

B2C Public-facing

B2C applications

Public-facing web apps where volume, speed and accessibility count: sign-ups, bookings, member areas, self-service. Built on measurable Core Web Vitals and accessible to WCAG, because your customers will not wait.

CRM & Power Platform Low-code where it fits

CRM and Power Platform

If you already run on Microsoft, building new is rarely the smartest move. Configuring Dynamics 365, Power Apps and Power Automate around your processes delivers faster — Forrester calculated a 206% ROI and roughly half the development time.

Integrations Connections

System integrations

The invisible backbone of your landscape. By letting separate packages talk to each other, information flows on its own and manual re-entry disappears. From Microsoft CRM to legacy ERP — we build the bridge between the islands.

Insight Real-time

Business dashboards

Scattered data turned into one clear picture showing the pulse of your organisation. Real-time insight into the KPIs that matter, so you steer rather than react after the fact.

Internal Bespoke

Department apps & workflows

One department's challenges translated into a tool that fits their daily reality exactly. Not a rigid off-the-shelf package you have to work around, but something that does what they need.

From idea to production

Process analysis We model the process before drawing a screen. What the app must do follows from how you work.

Platform choice Standard platform, low-code or bespoke — argued, with the three-year cost alongside it.

Building in sprints Working software every sprint, on a staging environment you can inspect yourself.

Pentest & go-live An external penetration test before delivery, then go-live with documentation and handover.

What that looks like in practice

Custom-built for the complexity that standard software can't handle.

Standard platform or bespoke? The answer usually costs you money.

A Dynamics 365 implementation typically runs between €30,000 and €350,000 for a mid-sized Dutch organisation, with licence costs continuing every month afterwards. That is money well spent when your processes sit close to the standard and you are already inside the Microsoft ecosystem. It is money wasted when you then spend a hundred hours bending the platform into something it does not want to be. I work through both scenarios with you — including licence costs over three years, because that is usually where the difference sits. Sometimes the answer is Power Apps. Sometimes a bespoke application. Often a combination: the standard platform for what is standard, bespoke for the part where you differentiate.

AI is not a feature. It is how we work.

AI sits in our process, not in our sales pitch: in discovery to turn sessions with your department specialists into structured documentation, in development to build faster, in testing to cover more scenarios than would be feasible by hand. That costs you no quality but saves lead time — and it is the reason a small practice can take on work that normally requires a team.

No hype. Only quality.

Every app goes through an external penetration test.

When delivering an application that touches personal data, payments or client files, I have a penetration test carried out by a certified party — not by myself, because checking your own work is not a check. The report ships with the delivery, including the remediated findings. I do not do that because it looks good: NIS2 now requires organisations to set security requirements for the parties that build software for them. When your accountant, insurer or largest client asks how your supplier chain is secured, you already have the answer on file. The scope of the test scales with the scope of the application, which keeps it proportionate.

Checking your own work is not a check.

Why build with SpineTech?

Senior-led

The person who makes the design is also at the table at delivery. No account manager in between, no junior learning on your budget. Traditional agencies bring layers of management and bloated teams — you pay for that in time, cost and quality.

Platform-independent

I sell no licences and therefore have no stake in your choice. The advice follows from your processes and the three-year cost, not from a partner programme.

Continuity in the build

For the build I work with senior developers I select per engagement against the same standards. The partnership is aimed at continuity, so knowledge of your system does not walk out of the door when an assignment ends.

European hosting

Your data and your customers' data stay in Europe. GDPR compliant, with the processing agreements in order. We integrate with any LLM you choose, including self-hosted models.

Which application would make your work easier?

Describe the process or the customer problem. I will tell you what it costs to build — and whether you would be better off buying it.
