Julien Wüst

Hey there, nice to e-meet you!

I'm Julien — a Technical Consultant at NTT DATA, based near Frankfurt am Main. With a Bachelor's in Software Technology, my work sits at the intersection of cloud infrastructure, software architecture, and increasingly, AI.

Outside of work I'm probably planning my home lab, bouldering, staying fit with calisthenics, or out with my camera. My fiancée and I also travel whenever we can — and document it all on our YouTube channel, ScenesWeKept.

I'm currently working toward my AI-103 certification and, slowly but surely, learning Spanish.

Completed

Personal Website

Built this portfolio from scratch before starting my first full-time role — a hands-on dive into modern web development to get familiar with HTML, CSS and JavaScript outside of a professional context.

Completed

Spanish Trainer

Built this because existing apps fell short for me — too little grammar context, no real study tips, and no focus on Latin American Spanish. Tailored to my own life and vocabulary, using spaced repetition (SM2, same principle as Anki). A React PWA with Google auth and cross-device sync via Firestore — installable on phone and desktop, works offline.

myCloset

A digital wardrobe app built for my fiancée — existing closet apps get cluttered fast with features nobody asked for, so this one is tailored exactly to her wishes. Photograph clothes with automatic background removal, track what's in the laundry, combine outfits and let the outfit finder roll colour-matched looks.

Building

Home Lab

Self-hosted infrastructure on Proxmox VE, a Synology NAS and Raspberry Pi. Runs Nextcloud, Immich, Home Assistant, a full monitoring stack and a custom AI layer — all secured via Tailscale VPN with no open ports.

Shared App

A shared PWA for my fiancée and me — shopping list, notes and calendar with real-time sync via SignalR and AI-powered features like autocomplete, categorisation and semantic search.

Second Brain RAG

A retrieval-augmented generation pipeline that indexes my Obsidian vault and lets me query my own knowledge base in natural language — the same concept as Azure AI Search, built locally with ChromaDB.

AI Agent

A Semantic Kernel agent in C# that orchestrates tools across Home Assistant, Obsidian, calendar, shopping and the web — using auto function calling to handle multi-step tasks autonomously.
