Omschrijving

I help companies turn complex data into actionable insights and intelligent applications by designing scalable pipelines, building robust back-end systems, and integrating AI solutions. With deep expertise in Python, SQL, and modern frameworks like Django, FastAPI, Pytorch, and LangChain, I deliver end-to-end solutions that combine clean architecture with high performance. My experience spans data engineering, AI-powered product development, and full-stack web applications—covering everything from ETL workflows and API integrations to Retrieval-Augmented Generation (RAG) pipelines and ML model feature engineering, training, evaluation, and deployment. I excel in fast-paced, collaborative environments, and my track record includes projects for startups, enterprises, and regulated industries where quality, security, and scalability are paramount.

I have an extensive portfolio on GitHub with samples of my work:
