Project: saveFOOD
This project aimed to create a digital marketplace platform tailored for regional grocery stores, enabling them to publish special offers directly to end consumers and thereby contributing to the reduction of food waste.
The project was structured into two specialized teams: the platform team and the app team. In my role as a member of the platform team, I played a key part in developing a scalable RESTful API, which served as the backbone for the app team’s front-end implementation. Furthermore, I was responsible for designing and implementing intuitive CRUD interfaces for various data entities, ensuring seamless data management and user experience.

Activities:

• Designed and implemented comprehensive CRUD interfaces leveraging Symfony, Twig, and Stimulus to enhance user interaction and data management.
• Engineered and maintained RESTful API endpoints, ensuring robust functionality and clear documentation using OpenAPI schema standards.
• Containerized the platform project using Docker, optimizing deployment and scalability.
• Conducted thorough code reviews to uphold high standards of code quality, maintainability, and best practices.

Project: Online Store Relaunch
Holzland Becker stands as one of Europe’s leading retailers specializing in wood-based products, with a diverse portfolio that includes garden sheds and houses, flooring, doors, saunas, and more. As the company expanded its e-commerce operations across multiple European markets under various established brands, the need to adapt its digital infrastructure became increasingly urgent.
To align with the demands of this growth, the e-commerce platform required significant modernization. The primary objective was to overhaul the existing online stores and architect a new multi-brand commerce platform. That not only enhances flexibility but also accelerates the time-to-market for launching new digital storefronts.

Project: Akeneo Integration and Middleware Development
Holzland Becker relied on an obsolete product information management (PIM) system built on Microsoft Business Central. Faced with evolving license terms and growing dissatisfaction with the tool’s limitations, the company sought a modern alternative. The selection process prioritized essential criteria, including robust multi-channel capabilities, an intuitive and user-centric interface, and a well-documented, extensible API to facilitate seamless integration with diverse sales channels like Shopware, Amazon, and Ebay.
Following a rigorous proof of concept and a comparative evaluation of leading PIM solutions, Akeneo Community Edition emerged as the optimal choice. The project objectives encompassed the full integration of Akeneo, the development of custom middleware to ensure consistent product data distribution across all sales channels, a comprehensive restructuring of data models, the optimization of internal workflows, and a structured training program to empower staff with the new system.

Activities:

• Stakeholder Engagement: Facilitated effective communication and collaboration with key stakeholders to drive project success and organizational alignment.
• Project Leadership: Spearheaded end-to-end project management, ensuring alignment with strategic objectives and timely delivery.
• Integrated and deployed Akeneo on platform.sh.
• Integrated cloudinary for digital asset management.
• Designed and implemented Akeneo Connector (middleware) using DDD pattern and asynchronous message processing based on Symfony.
• Redesign and modeling of data entities.
• Implemented Akeneo to Shopware adapter (middleware).
• Implemented Akeneo to Amazon Seller Central adapter (middleware).
• Implemented Akeneo to Ebay Adapter (middleware).
• Implemented Akeneo to Cloudinary Adapter (middleware).
• Implemented CI/CD pipelines.
