Hi, my Name is Andre Petsch. Based in Germany I'm working as a senior consultant with a focus on Large language Models, Software Architecture and Software development in the German health system. My general interests reach from Information Systems to mechanical watches.
On my private web page I'm collecting thoughts, ideas and private projects - in the digital or analog world - technical and personal.
My CV:
2023 - now
PII - LLM - Health
At fbeta I started as a working student in the first uprise of Large Language Models in Business Environments and currently have the position of a Senior Consultant. My first Proof of concept was recording a talk, summarizing it with Openai's GPT 3.5 and having summaries from different viewpoints and in different languages on a Website. From there we went into the health space and built a GenAI Platform at one of Germanys largest public health insurances, that includes vector retrieval and RAG, a service to remove personally identifying information (PII) from texts, confidentially hosted Large Language Models and several more services.
I took part in the project e.g. by deploying LLMs over multiple confidential Nvidia H100, developing services as a software architect or developer, providing high level support for the system we built and helping with enterprise architecture.
Outside of the large GenAI project I managed to get my hands on a Kafka consumer that sinks information to a database and makes current processing states of requests and invoices visible for insurance customers. It turns out that choosing a good message broker architecture can be very hard and dealing with the aftermath of, let's say, suboptimal choices is even harder.
As a Senior Consultant my team and I are currently implementing the deidentification Service at several other health insurances with different objectives on the customers sides. Managing stakeholders, riscs and budgets also became part of my job.
I also put my knowledge about GenAI, Software Architecture and Software Engineering to work outside of the health sector by creating solutions for several other customers. I have some knowledge in programming languages like C, C++, C# and Java but my current mains are Python and the NextJS Framework.
