A full record of my professional engagements — from early-career Java development to AI-powered platforms for German enterprises.
The client operates in the broadcast media buying space and needed a modern platform to manage the full lifecycle of media orders, from estimate creation through order placement, execution, and reporting while staying synchronized with external broadcast industry systems. Our job was building and maintaining a full-stack media buying platform covering estimate creation, order management, and reporting, with direct integration into broadcast media platforms.
Designed and built an AI-driven automation layer to streamline B2B order intake. Extract Order AI transforms unstructured inbound orders — arriving via email, WhatsApp, or Jira — into validated, structured orders placed directly into connected backend systems. The solution integrates document OCR, AI-powered product and customer identification, confidence scoring, human-in-the-loop review, and direct ERP/e-commerce integration.
Steered a full digital transformation from a legacy ERP-only setup to a high-availability AWS ecosystem. Built a "My Portfolio" area for B2C/B2B customers and a Partner Portal, with Emporix admin dashboard extensions, ERP data synchronisation, secure login, portfolio and transaction views, document management, and a RAG-based AI chatbot.
Extended and showcased the Pimcore portal engine within a tight deadline, enabling the product to be demonstrated and sold to enterprise clients. Implemented specific features including bulk product upload/download, editing, and saving workflows tailored to Salsify's typical clients.
Contributed to developing a highly configurable global webshop blueprint designed for direct sales and lead generation, scaled to 30+ countries using SAP Commerce Cloud, Vue.js, and Spring Boot. Managed annual rollouts for 20+ regions via SAFe methodology. Participated in structured "firefighting" rotations for major incidents and on-call support.
Led the migration of an existing Android native courier app to React Native, with full rollout on Google Play Store and Apple App Store. Tazz is a country-scale food commerce and delivery company handling over 20,000 orders per day at the time of development.
Helped Eppendorf AG — one of the global leaders in biotech instruments and consumables — build a configurable B2C/B2B web shop and prepare it for adjacent services (Hawk, FirstSpirit, ERP) with multi-country rollout support.
Built a customised e-commerce shop with advanced features including print data upload, split order delivery, and custom quotations — configurable for multi-country rollout.
Worked on two internal tools: an employee skills management system, and a comprehensive operations platform covering vacation planning, hours tracking, inventory management, and custom report generation — delivered production-ready and configurable for resale.
Started as a part-time internship and transitioned to full-time. Worked on two projects: a Vacation Manager tool for internal HR use, and a plugin with custom functionalities for IBM Rhapsody software architecture tooling, including automated build integration via Jenkins.
