Hi, my Name is Andre Petsch. Based in Germany I'm working as consultant with a focus on Large language Model, Software architecture and 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 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 Services to remove personally identifying information (PII) from texts, confidentially hosted Large Language Models and several more services.
I took part in all of these services, e.g. by deploying LLMs over multiple confidential Nvidia H100, developing services as a software architect or developer and supporting the system and 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 aftereffects of, let's say, suboptimal choices is even harder.
In one Project outside of the health environment I became team lead to create the new Website for a running influencer, who is currently running one marathon a day with the goal to visit every City in Germany in 495 marathons. Techstack here is Payload backend, cusotm NextJS frontend, hosted on Vercel.
