• Development of PoCs, prototypes, and applications for German government agencies using open-source LLMs and frameworks

• Fine-tuned open-source LLMs on multi-GPU setups using Low-Rank Adaption (LoRA) • Evaluated LLM performance using perplexity metrics and standard benchmarks (e.g., SuperGLUE) • Applied and analyzed multiple quantization techniques with respect to latency, throughput, and model compression • Conducted cost analysis across the lifecycle of LLM-based applications • Analyzed performance–cost trade-offs between API-based LLMs and open-source LLMs deployed on-premise or in the cloud • Studied MLOps in the context of GenAI

• Backend and frontend development for GenAI PoCs and prototypes • Development of conversational agents using RAG, LangChain, LangGraph • End-to-end RAG implementations: data acquisition and preprocessing, creation of vector databases, prompt engineering, evaluation, and deployment • Scalable ML-based applications on Google Cloud Platform

• Data analysis and visualization utilizing Python, Excel, and Salesforce tools to generate strategic insights • Design, optimization, migration, and data cleansing of databases and ETL / ELT pipelines • Software development, deployment, and integration

• Implementation and optimization of thermomechanical processes (Friction Extrusion) • Designed and carried out scientific experiments, analyzing their data to generate insights and guide the next steps in the research

• Production of four types of stainless steels modified with boron using commercial materials and thermal spray processes. • Electrochemical and tribological tests to assess corrosion and wear resistance of the produced alloys, demonstrating their improved performance in harsh conditions and their suitability for applications in the sugar and ethanol industry
