Portrait of David Vercruyssen

David Vercruyssen
freelance developer · Antwerp

I build apps.

I've been building business software since 2006, and running Aranea as a freelancer since 2014. I design, build and maintain it all, from the first conversation to the server it runs on.

No account managers, no layers in between: you talk directly to the person who writes the code.

what I do

Consultancy
An extra senior on your team: development, technical design and architecture. I've led teams and set up projects from the first commit to production.
Custom software
When no off-the-shelf package fits, I build an application around the way you work, and keep maintaining it for years.
Websites & hosting
Simple, fast websites that I build, host and maintain on my own servers.
Training & coaching
Multi-day .NET courses and hands-on coaching for developers, backed by a teaching certificate.

open source

  • TempFileStorage

    NuGet · 20k+ downloads

    Takes the plumbing out of file uploads and downloads in ASP.NET Core: upload first, submit the form with a key, pick the file up on the server. Stores files in memory, SQL Server or Azure Blob Storage.

  • Re.MediatR

    NuGet · .NET 8–10

    Exposes MediatR through a single Web API endpoint, so Angular, React or Vue apps can call your request handlers without you writing controllers.

  • bad-files-check

    Dropbox API

    A console tool that finds and fixes files that won't sync to Dropbox, built as a stand-in while Dropbox's own checker was unavailable.
