I build AI-powered SaaS platforms, LLM workflows, and scalable full-stack applications.

I've built AI-powered SaaS platforms and reusable cloud-native frameworks at Amprela GmbH, reducing delivery time by approximately 80%. I develop LLM workflows, AI agents, backend services, API integrations, and user-facing features that automate practical business workflows.

Previously, I delivered production applications for Akkodis, Canadian National Railway, and UGroupMedia across cryptocurrency, logistics, and customer-facing products. My work spans Python, TypeScript, React, Next.js, cloud infrastructure, mobile applications, REST APIs, and real-time data pipelines, including deployments that were 57.5% faster with a 99.5% success rate.
