Projekte & Fallstudien
Eine Auswahl von Software-Engineering-Projekten mit groĂźer Wirkung. Diese Fallstudien zeigen tiefe technische Einblicke in Performance, Skalierbarkeit und durchdachte Architektur.
01. Poster Gifts
Creating a clean and scalable e-commerce flow for digital products while maintaining clear boundaries between server and client logic.
Implemented a modular e-commerce architecture using Next.js App Router, server components, and API routes, with a focus on maintainability, predictable data flow, and reusable UI patterns.
02. CAM: Enterprise SaaS Platform
Building an enterprise SaaS platform for data governance, provisioning, and security across Microsoft 365 and other enterprise content systems—with a microservices architecture enabling organizations to provision, classify, protect, and minimize data while reducing privacy and cybersecurity risks.
Primarily responsible for frontend/UI development within a microservices-based architecture, building complex, data-driven interfaces using CxJS (React-based) with strong emphasis on usability, accessibility (WCAG), and performance. Implemented reusable UI components and screens supporting provisioning workflows, metadata management, and administrative features. Collaborated closely with backend engineers and occasionally contributed to Node.js and AWS Serverless integrations. Worked in an Agile/Scrum environment with active participation in code reviews, debugging, and feature delivery.
03. Custom Map Poster Generator
Server-side poster generator that turns a location and custom text into a printable, high-resolution map poster. Geocodes the place, fetches a static map, composites it with typography (multiple fonts), optional shape masks (rectangle, heart, circle), and coordinates, then outputs PNG previews and print-ready PDFs. Built to run in serverless (e.g. Vercel) with no reliance on system fonts.
Built the full server-side image pipeline: geocode → static map → composite map, text, and watermark → PNG preview and PDF. Custom fonts rendered as vector paths (opentype.js) with base64 fallback for serverless. Print-ready PDF at 300 DPI for standard sizes; shape masks, multiple typefaces, and preview vs final mode. This module powers the poster generation for the Poster Gifts e‑commerce site.
04. AI Product Data Generator
Helping small businesses quickly generate consistent, SEO-friendly product descriptions without manual copywriting.
Built an AI-assisted content generation tool with controlled prompting, validation, and error handling to produce predictable, reusable product descriptions suitable for real-world usage.
05. Enterprise Cloud Document Admin Dashboard
Enterprise admin dashboard to centrally search, audit, and manage Microsoft 365 OneDrive documents across multiple users using Microsoft Graph APIs. Built with a microservices-style backend (Node.js, AWS Lambda, DynamoDB) and a CxJS-based frontend.
Frontend and UI development for document management and admin workflows using CxJS, Webpack, and Sass; integration with OneDrive/Microsoft Graph and OAuth; backend services with Node.js, AWS Lambda, and DynamoDB. Emphasis on usability and accessibility.
