Projekthistorie
- Led the development of a frictionless, computer-vision-based IoT checkout system using Trigo Computer Vision AI, Node.js, React, Kubernetes and Azure. The solution won the 2023 RETA Award for Best AI & Robotics.
- Launched the MVP from scratch, scaling it from one store and payment method to a multi-country and multi-payment rollout.
- Owned the technical roadmap and KPIs while leading cross-functional delivery across 8 partner teams including IoT, payment, and inventory systems, using Jira/Confluence and Agile workflows.
- Delivered the production-ready solution in 13 months; reduced checkout times by over 90% and improved customer satisfaction across several pilot locations.
- Designed internal apps to enable remote testing and simulation of end-to-end in-store customer journeys.
- Assessed engineering gaps and reorganised the team structure to sustain delivery speed during staffing transitions.
- Mentored junior engineers and coached senior developers on system architecture and delivery practices.
- Facilitated technical decision-making workshops, helping partner teams align on design trade-offs and improving delivery speed despite staffing transitions.
- Started the modernisation by targeting the core RFQ workflow as a lean MVP, then progressively scaled improvements across all major features to replace the legacy system.
- Re-architected Europe’s largest manufacturing sourcing platform with micro-frontends (TypeScript, React, Redux, Material-UI) for better modularity and team autonomy.
- Reduced RFQ processing time by 20× through backend optimisation and frontend re-architecture.
- Enhanced buyer-supplier interaction through UI/UX upgrades, increasing user satisfaction and supplier engagement in complex RFQs.
- Led multi-division transformation of reporting workflows and large-scale data integration and analytics initiatives, migrating legacy Excel workflows into scalable QlikView dashboards and Git-based versioning.
- Automated Excel-to-QlikView logic migration, improving data integration speed by 6× and enabling better cross-division decision-making.
- Implemented parallel Kanban pipelines and DevOps processes to enhance efficiency in a high-complexity, multi-division environment.
