Projects
Selected projects & case studies
AI & enterprise automation
-
Automating enterprise workflows with AI & RAG
Approach: Design and production deployment of tailored AI architectures and prototypes using Adobe Firefly, Adobe tooling, and integration with multiple third-party language models.
Outcome: Manual media and production chains were automated, cutting cycle times and operating cost.
-
High-throughput migration for enterprise data estates
Approach: Architecture and implementation of an automated validation and migration pipeline with Python and Django for very large data volumes.
Outcome: Reliable transfer of business-critical data into Adobe target systems at maximum throughput with validated integrity.
Real-time & critical infrastructure
-
Real-time control for fully automated intralogistics
Approach: High-performance, fault-tolerant system architecture to operate and monitor autonomous warehouse systems with Python and Angular.
Outcome: Stable, uninterrupted operation of critical logistics infrastructure with near real-time plant control.
-
Real-time monitoring for data center infrastructure
Approach: Design and implementation of a central management and monitoring platform for data center infrastructure. It consolidates real-time metrics and status from live operations, supports the ops team in day-to-day supervision, and surfaces deviations and incidents early.
Outcome: Full visibility into complex data center systems and immediate detection of states and incidents.
-
Crisis-ready document management for emergency operations
Approach: Design, architecture, and implementation of a central document management system built on Plone (CMS). The platform was created for emergency operations in banking infrastructure to store, manage, and deliver business-critical documentation reliably in exceptional scenarios.
Outcome: Business continuity and dependable access to critical documentation during external emergencies.
-
Live fleet tracking & dynamic ETA forecasting
Approach: Design, architecture, and full-stack implementation of a web application for real-time fleet tracking: live driver positions, dynamic ETA calculation, and analytics dashboards for dispatch.
Outcome: Precise shipment visibility in live delivery operations plus actionable insights for dispatch.
High-performance web & e-commerce
-
Scalable e-commerce architecture on open source
Approach: Ongoing development and performance tuning of the Python/Django shop framework django-lfs, plus technical lead for live operations.
Outcome: Smooth handling of high-frequency e-commerce traffic on production sites such as holzimgarten.com.
-
High-performance REST API manager
Approach: System architecture and implementation of a central, scalable API management layer. It consolidates REST interfaces, governs access and load, and provides a robust foundation for data-intensive enterprise applications.
Outcome: High data throughput and controlled interface governance for data-intensive enterprise applications.
-
Scaling high-reach comparison portals
Approach: Platform evolution, performance work, and new features for heavily trafficked online portals.
Outcome: Stable delivery and fast response times under heavy user load.
-
API integration & architecture for specialist portals
Approach: Modular portal components and external integrations across Haufe Group information portals.
Outcome: End-to-end data flow and consistent delivery of specialist content across multiple platforms.
-
Booking and sales platform for specialist seminars
Approach: Built a seminar platform with shop and CMS for hundreds of legal seminars, from presentation through online booking. Via integrations, bookings and seminar data are automatically passed to internal administration and billing.
Outcome: The full seminar program is bookable online, with no manual double entry between sales, operations, and billing.
