I'm building an Agentic Virtual Assistant at Formula - Impresoft, using a Graph-RAG architecture to improve ERP software usability and progressively augment its knowledge base from customer data.

I orchestrate agent workflows with LangGraph and LangFuse, combine hybrid retrieval in ChromaDB with graph-based context resolution in Memgraph, and manage bare-metal NVIDIA GPU inference infrastructure using llama.cpp. I also integrate computer vision for business-document extraction and deploy containerized microservices through Docker, docker-compose, GitHub Actions, and CI/CD pipelines.

Previously at Certimeter - Lutech Group, I built distributed PySpark ETL and DBSCAN clustering pipelines across HDFS, Impala, Hive, and Cloudera environments to support banking-user segmentation and security anomaly detection. At Alten, I maintained Java systems and developed an NLP classifier for automated ticket routing.

My work also includes optimizing Vision Transformers in PyTorch for nano-drones, where structured pruning delivered a 13% improvement over state-of-the-art CNN baselines, and time-series forecasting projects where LightGBM improved MAE by 25% over naive baselines.
