Project portfolio
Check out some of my work in server infrastructure, web development, databases and AI-powered systems.
System Administration
I run and maintain the production environments for gravyrochlaser.se and gravyrhandeln.se. I administer the Linux server that runs the portfolio projects and company websites. The work includes Nginx, HTTPS/TLS, systemd services, PostgreSQL, deployments, logs, backups, file uploads, admin tools and troubleshooting production issues.
Projects
A full-stack app that finds similar second-hand items based on an uploaded image or text. Built with PostgreSQL, Flask, Vite, React and a self-finetuned CLIP model trained on data I collected myself. The app is self-hosted on Linux infrastructure.
Read about the model and applicationA deep learning project where I developed ESCNet, a custom CNN model that classifies environmental sounds from Mel-spectrograms. The model was trained on ESC-50, evaluated with cross-validation and deployed in a real-time desktop application using ONNX Runtime.
Fine-tuning CLIP ViT-B/32 with self-collected product data for image and text similarity search. See details on my GitHub.
Interactive data visualizations of Uber rides in New York, cars and the Covid-19 pandemic. Built with Python, pandas, NumPy and Plotly.
Extra:
This website and connected projects, including databases, frontend builds and backend services, are self-hosted on a Linux server. See live server statistics.
