For

For anybody, personal or business — who needs a clear, maintainable online presence without a large agency budget.

Deliverable

Responsive website or compact web app, ready to deploy. Optional integrated content manager so non-technical colleagues can update pages, downloads and team info without touching code. Tech stack tailored to your context — e.g. Next.js/React, Astro, or a lightweight CMS-backed setup.

Working demo or prototype you can click through and share with stakeholders. Core user flows implemented and ready to test with real users. Short usage guide and prioritized backlog for follow-up phases. Tech stack matched to your goal — e.g. Next.js/React, Python/Streamlit, or a lightweight API-backed setup.

€2,500–€4,000 excl. VAT

For

Teams with Excel, CSV or database sources (SQL, PostgreSQL, MySQL, etc.) that need a clear overview.

Deliverable

Interactive dashboard as a web page or Windows desktop app, connected to your data sources. Filters, charts and drill-down views tailored to the questions you need answered. Export to Excel, CSV or PDF for reporting and sharing. Works with Excel, CSV and SQL databases (PostgreSQL, MySQL, etc.) — from uploaded files or live connections.

7–10 days

€3,500–€5,000 excl. VAT

For

Organisations that want manuals, SOPs or FAQs searchable with source references.

Deliverable

AI assistant with your documents (manuals, SOPs, FAQs) indexed and searchable. Answers include source citations so users can verify information. Deployable via web, WhatsApp or Telegram — channel chosen to fit your users. Built with RAG over your content, with human-in-the-loop guidance and guardrails. Tech stack: OpenAI or similar LLM, vector search, Open Chat Studio or custom integration.

Good to know

  • Privacy & compliance

    Software and data handling are set up in line with GDPR, the EU AI Act and additional requirements where needed — privacy-by-design from the start.

  • Pricing

    Indicative, depending on scope. Always fixed-price after intake.

  • Availability

    I deliberately take on a limited number of small, well-scoped projects — no large programmes.

  • KNCV separation

    Freelance work is separate from my KNCV role: no KNCV data, code or assets; no competing assignments.

Who I am

Who I am

Freelance software developer with a product-minded, end-to-end delivery approach.

Practical digital tool builder

I take on a limited number of small freelance assignments — websites, prototypes, dashboards, AI knowledge assistants and compact web apps for NGOs, consultants and small teams. See the services section for fixed mini-packages. I also build personal projects (like Memory Mania and experimental AI demos) with the same hands-on approach.
