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
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
Built this because existing apps fell short for me — too little grammar context, no real study tips, no focus on Latin American Spanish. It now covers French and English too, schedules reviews with FSRS-6, and adds an AI conversation partner, a live translator and spoken pronunciation. Five of us use it: my fiancée, my sister, my parents and me.
Completed
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
The shared household app for my fiancée and me — shopping list, recipes and pantry, calendar, shared expenses, chores and trips in one place. The shopping list learns the order you walk the aisles in, recipes scale to the number of people eating, and expenses settle up fairly instead of splitting everything in half.
Self-hosted infrastructure on Proxmox VE, a Synology NAS and a Raspberry Pi — Nextcloud, Immich, Home Assistant, a monitoring stack and a custom AI layer, all reachable over a Tailscale VPN with no open ports.
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.
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.
Life outside the IDE — travel, photography, and everything in between.
A travel & life channel my fiancée and I started together — documenting the places, moments and stories worth keeping.
