Background

About Stijn Hering

Engineer specializing in Data, AI/ML, Software and Cloud solutions. I build the infrastructure and applications that make data useful, from large-scale migrations, web/data-apps, tools to (generative) AI projects. Data & ML Engineer @ TenneT (via Team Rockstars IT): Driving a large data migration from on-premise to the cloud & innovating the overall developer environment. The stack includes Azure, Databricks, PySpark, and modern DevOps practices to build a resilient and scalable data platform. Highlights from PostNL | AI Center of Excellence & Data Engineering: Spearheaded Data Science Portal: Architected and deployed an internal portal using AWS CDK, enabling 40+ data scientists to build and run over 30 production Streamlit apps. 🤖 Pioneered Generative AI Solutions: Developed key projects with models from OpenAI, Anthropic, and AWS Bedrock, including "PostNLChat" for employees and an AI-powered sales call summarizer. Strengthened Data Foundations: Managed ETL pipelines, integrated new sources into the data lake, and applied predictive modeling to guide business strategy. Personal Projects Driven by a passion for tinkering with new tech, my personal projects are my playground for learning and building. I enjoy the challenge of creating useful things, from simple demo projects to full-stack applications. My most recent major project is my Master's Thesis, for which I engineered a platform to benchmark AI agents within a fully sandboxed, graphical OS environment, see the link below if you want to know more! ↪ Project Link: https://github.com/melchiorhering/GUI-OS-AI-Agent-Benchmarking Core Competencies: Programming: Python, JavaScript/TypeScript, Rust Cloud & DevOps: AWS, Azure, Databricks, Docker, Podman, Linux, CI/CD, Git, Bash, Github Actions, Azure Devops Data Engineering: PySpark, Polars, Pandas, ETL, Big Data, SQL Data Orchestration: Dagster, Prefect Data Science & AI: Machine Learning, AI (Generative, VLMs/LLMs) Web: React, Astro, Next.js, FastAPI, Streamlit, Marimo, TailwindCSS Feel free to connect if you're interested in tech-driven innovation!
