As a Senior Backend Engineer at Ingram Micro, I built an “Environment as a Service” platform enabling seamless third-party integrations, real-time event handling, and automated multi-cloud provisioning. I also modernized legacy payment workflows from plain PHP to Symfony, enhancing scalability and reliability. With infrastructure tuned for 1,000+ RPS, 90%+ test coverage, and rigorous code reviews, I delivered a future-ready, high-performing ecosystem.
I contributed to the development of a high-performance SMS gateway for Cloudtxt.com, creating an event-driven system that integrated seamlessly with multiple SMS providers. This allowed the gateway to instantly select the most cost-effective route for sending each message. In addition, the system processed incoming SMS messages and triggered corresponding marketing scenarios—flexible chains of tasks with their own startup triggers. As a result, Cloudtxt.com now offers a highly responsive, cost-efficient SMS delivery platform, optimized for evolving business needs and rapid scaling.
I built a high-performance ETL middleware solution for klium.be that seamlessly integrated and enriched supplier data from Kafka into their Symfony-based online store. The system transformed product information—prices, descriptions, and stock levels—in under 30ms per request, ensuring near real-time accuracy for customers. Powered by Go, it featured robust fault-tolerance and handled heavy loads without downtime. As a result, klium.be’s storefront now operates with streamlined data flows, enhanced reliability, and the agility to quickly adapt to market changes.
