Team Conductor

Association Management Software

Professional association management software for member communication, finances, events, surveys, and attendance.

Team Conductor helps clubs and associations communicate with their members, conduct surveys, manage finances, organize events, and track attendance.

I designed and developed the multi-tenant progressive web application, companion Android and iOS apps, and the bilingual English and German product website.

Team Conductor has long been built and maintained as a professional software product, but active promotion took a back seat while I focused on other projects. From 2026 onward, the goal is to bring it to a wider audience and establish it as a professional solution for clubs and associations.

The platform was initially hosted in the Amazon Web Services (AWS) Frankfurt region. Elastic Beanstalk was the first deployment approach, followed by infrastructure managed with CloudFormation and containerized services running on ECS and Fargate. The architecture also used RDS, SES for transactional email, SQS for queues, SNS for notifications, S3 for object storage, EFS for network storage, and CloudFront for content delivery.

In August 2026, most of the infrastructure was migrated to Docker Compose, with only transactional email delivery remaining on AWS SES. For an environment comprising six services, a load balancer, and the web UI, the new setup is expected to reduce infrastructure costs by up to two-thirds compared with AWS while retaining ample capacity and operational flexibility for continued innovation.

Open Source

Open Source Contributions

Capacitor plugins and other open source projects giving back to the developer community.

Everybody uses open source technologies for their work, but few give something back. As a freelancer, that’s not so easy to do, but I try to at least report issues and eventually create some useful stuff for others.

Current Projects:

  • Capacitor OAuth2 — Simple and generic plugin for Capacitor letting you configure providers instead of having to integrate with all the SDKs
  • Capacitor FileSharer — Downloading files
  • Capacitor SMS — Sending SMS on Android
