What I'm looking for

I'm looking to build practical software and AI workflows for scientific or biological applications, collaborating closely with researchers to turn their needs into reliable, tested tools.

I've built backend services and research interfaces at NanoTemper Technologies, modelling complex biological assays for SaaS applications with Python, FastAPI, PostgreSQL, React, and REST APIs.

During my AI research internship at Japan's National Institute of Informatics, I built LLM, RAG, and prompt-engineering workflows to help researchers verify scientific claims against evidence. I fine-tuned PyTorch and Hugging Face Transformer models and packaged workflows as APIs, CLI tools, and batch processes.

I've also developed JavaFX software for 3D bioprinting at Black Drop Bioprinting, working directly with researchers to turn laboratory requirements into tested features. I'm completing an M.Sc. in Bioinformatics and enjoy building practical software that supports scientific work.
