About
Peter Placzek tada5hi
I build open-source infrastructure for the modern web, from HTTP frameworks and auth servers to Vue component systems.
My name is Peter Placzek, tada5hi on GitHub. I was born 1996 in Reutlingen and work as a fullstack engineer and researcher at the University Hospital Tübingen, building open-source data infrastructure for personalized medicine.
Most of what I build rests on open-source libraries I maintain in my own free time: 240+ npm packages with more than 35 million downloads a month, among them authup (identity & access management), the routup HTTP framework, the vuecs component system, typeorm-extension, smob and rapiq.
In research I co-develop DNPM:DIP, the data integration platform of the German Network for Personalized Medicine, and lead the technical side of PrivateAIM (hub, infrastructure & cloud): privacy-preserving, federated analysis of medical data.
In my free time I like to go jogging, play volleyball, do weight training or ride my bike.

Research
Alongside engineering I work in medical informatics research at the University of Tübingen.
Personal Health Train (PHT)
Privacy-preserving distributed analysis of medical data: instead of moving patient data, the analysis travels to the hospitals. I build security layers, UIs, backend APIs and microservices for the train infrastructure.
PHT-MedicPrivateAIM
Privacy-preserving Analytics in Medicine, a platform project of the German Medical Informatics Initiative (MII) with 17 partner institutions. Its platform FLAME (Federated Learning and Analyses in Medicine) brings the analysis to the hospital: raw data never leaves the site, only results come back. As technical lead I am responsible for the hub, its Helm charts and releases, and the cloud infrastructure, with our own Kubernetes environments managed via GitOps (Flux).
PrivateAIMDNPM:DIP
Portal, client libraries and modules for DNPM:DIP, the data integration platform of the German Network for Personalized Medicine (DNPM). It connects molecular tumour board and rare disease data across university hospitals, so cases with rare alterations can be compared between sites. Started as my Master's thesis; I also maintain the platform's Helm chart.
Covid-19 Dashboard
Development of a Nuxt.js single-page application & design for the Covid-19 dashboard at the University Hospital Tübingen.
