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.

My Journey

Greenfoot

First contact with programming — I built a game in school called "Räuber und Gendarm"
Java

Learned more about object-oriented programming and Java basics
SQL

Figured out what relational database terminology means and how database queries work
Arduino UNO

As a school project I built the "hot wire" game using Arduino UNO — I needed to write code, solder different parts and used 3D printing for the case
C#

With C# and Windows Forms I built a calculator as an entry project for my job and an app for a final school project for calculating final grades
MS-900 Certificate

Started to focus on Microsoft certificates and cloud-related topics
AZ-900 Certificate

First cloud certificate — learned fundamental concepts in Microsoft Azure
IaaS on Azure + Terraform & CI/CD

In my first practice-oriented study phase I defined an architecture with Terraform and implemented it as IaaS on Azure with GitLab CI
HTML/CSS & JS

The second practice-oriented phase was all about building a loyalty system website with HTML, CSS and JavaScript in ServiceNow
Android App Development

Finally got into app development. The app taught different sorting algorithms — my team implemented the Heap-Sort algorithm
React Native

In my 4th semester my fellow student and I created a currency converter that fetches live exchange rates through an API
Python

During my bachelor's we used Python to explore artificial intelligence and various extensions
Microcontroller Embedded C

Started from scratch, soldered parts onto the circuit board and wrote code for different tasks, e.g. a traffic light system. Quickly figured out that I don't like C
Domain-Driven Design

The entire 6th semester was practice-oriented — I evaluated whether Domain-Driven Design can be used to refactor a legacy Java application with >500K lines of code, using SonarQube and Sonargraph for static code analysis
B. Sc. in Software Technology

Three and a half years — how time flies! I'm really proud of what I've achieved and looking forward to the years ahead
Fulltime Job

After years of continuous learning I started my full-time role at NTT DATA as a Technical Consultant — and I couldn't be happier
Fullstack & Azure AI

Became the sole fullstack developer for an enterprise banking-sector intranet portal — Angular Micro-Frontend, C#/.NET, Azure AI Search and Cosmos DB. Helped shipping an EntraID migration and automated CI/CD pipelines
GenAI Certifications

Completed the NTT DATA GenAI certification track (White Belt → Yellow Belt L1 & L2) and the Linux Foundation Green Software Practitioner certification — deepening my understanding of responsible and AI-augmented development
AWS Solutions Architect

After the Azure Fundamentals certificate, I decided to explore the competition and pursued the AWS Associate Solutions Architect certification
AI-103 Certificate

Pursuing the AI-103 certification to deepen my knowledge in AI workloads and intelligent solutions — a logical next step given the direction the industry is heading
Home Lab

Planning a self-hosted home lab to experiment with infrastructure, networking, and services — because the best way to learn is to build it yourself

Projects

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.

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.

Proxmox VE Docker Synology NAS Tailscale Raspberry Pi Grafana

Planned

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.

Angular C# .NET PostgreSQL SignalR Claude API PWA

Planned

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.

Python ChromaDB FastAPI RAG Embeddings Obsidian

Planned

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.

Beyond Code

Life outside the IDE — travel, photography, and everything in between.
