Services

Six specialist services, one working system

Not separate projects, but an integrated system: each service strengthens the other. From advice and AI automation to custom platforms and security — together from idea to working system.

One connected foundation

Start with a website. Grow into a working system.

LaventeCare combines the public website, secure data flows, automation and monitoring in one technical direction. You can start sharply scoped today, without blocking tomorrow’s next step.

Why LaventeCare?

A long-term partner that turns the way you work into software that does the work for you: from intake and Blueprint (the build plan) to build, maintenance and further development — with built-in security.

One point of contact, full ownership

From intake to go-live — one fixed point of contact who knows your processes and system inside out. No rotating developers, no miscommunication, no knowledge loss.

Security-first architecture

Your data is strictly separated per client and every action is logged. Under the hood: Privacy by Design with PostgreSQL RLS, role-based access (RBAC) and full logging.

Measurably faster, demonstrably better

I measure speed and stability per project and optimise for real-world use. A lightweight technical foundation is the starting point, not a blanket promise.

About LaventeCare

What exactly does LaventeCare do?
LaventeCare is the company of Jeffrey Lavente, based in Dronten, Netherlands. I build professional websites and complete business systems: from a fast online foundation to portals, IoT monitoring and AI automation. I add only the technology and security that the specific requirement needs.
Who is LaventeCare for?
I work exclusively B2B and focus on three groups: (1) Industry and installation technology that wants to read hardware and sensors remotely, (2) SMEs looking for custom portals for relationship management and client files, and (3) Organisations and foundations requiring reliable registration, ticketing and donation platforms.
How does LaventeCare differ from a web agency?
You can start with a clearly scoped website package, without being locked into a page builder or a supplier that only knows the front end. The same engineer can later add secure forms, enquiries, automation, dashboards and integrations. Your technology grows without starting again.

Security & Privacy

How do you guarantee data security?
Security is my foundation, not an optional plugin added later. This is based on a "Zero-Trust" principle: we strictly validate and isolate all input data. Client records are fully digitally separated from each other, and we minimise dependency on unstable third parties. This structurally reduces the risk of major data breaches at the source.
How do you protect a portal with multiple users/clients?
Each tenant, client or location gets their own isolated vault within the database ("Tenant Isolation"). Advanced access controls in the background continuously verify the identity of the user. Even if unexpected erroneous behaviour occurs, the system automatically refuses access to others' data. Every action on the platform is traceable.
Are the custom platforms GDPR compliant?
Designed according to Privacy by Design and GDPR principles. I collect only data that is strictly necessary (data minimisation), sensitive information is stored encrypted and retention periods are digitally enforced. Final compliance depends on the specific configuration, usage and additional agreements — such as a data processing agreement, which is available.

Costs & Investment

What structures your investment rate?
Clarity upfront. Website packages have a fixed build price from €750. Website Care costs €29 per month for Start, €49 for Business and starts at €75 for Custom. Systems development usually starts with paid research and then uses a fixed price per milestone.
Am I financially committed if I only start a Discovery?
No, absolutely not. The Discovery and Blueprint design phase is a standalone product. If this research does not produce the desired picture or price tag, the collaboration stops there. The Blueprint document, including all analyses and system requirements, is then yours. You can then take it directly to another party if you wish.

Services & Expertise

What does the AI Automation service actually involve?
It goes beyond "just asking ChatGPT something". I use AI as an accelerator inside a controlled workflow: I design the blueprint, set security boundaries, test outcomes and remain responsible for the result. Recurring tasks — from document processing to reporting — can therefore require measurably less manual work.
Why do your applications and portals perform so fast?
I choose a lightweight technical foundation and load only what the visitor needs. Performance is measured per project on real pages and devices, after which images, code and third-party scripts are optimised. Results always depend on content, integrations and usage conditions.
Can existing equipment or sensors (IoT) be connected?
Yes, this is the bridge between the physical and digital world. I develop and connect measurement equipment (e.g. temperature, location, or power consumption) that sends data directly in real time to a secure cloud dashboard. You get insight anywhere, anytime via your phone or PC, including immediate alerts on critical deviations.

Process & Approach

How does starting a project work?
We start with a free 30-minute call. A fixed website package then follows the fast track: complete content, build, consolidated feedback and launch. Systems involving accounts, databases, integrations or business processes first use paid research and a technical build plan (Discovery and Blueprint).
How does my application keep running after go-live?
A separate SLA is available for custom systems. Depending on the plan, it includes automated availability monitoring, security updates, patches and reserved support hours. I agree response times, service windows and exceptions upfront; Website Care uses a lighter agreement for normal websites.
