What I'm looking for

I’m looking for a senior full-stack role where I can integrate AI into production products, own end-to-end delivery, and improve maintainability, performance, and reliability with a collaborative team.

I’m a Senior Software Engineer with 8+ years of experience building scalable web applications, backend systems, and AI-integrated product platforms across startup and enterprise environments. I focus on clean system design, maintainability, performance, and reliable production delivery.

At reanmo GmbH, I lead development and maintenance of customer-facing and internal platforms supporting high-volume ordering, reporting, and operational workflows. I’ve delivered full-stack features across React, TypeScript, Node.js, Python, Java, and PostgreSQL, built analytics dashboards, and developed AI-powered analytics workflows in Python that surface actionable operational insights.

Previously at Twin Sun and Share IT, I implemented AI-powered features like document classification, semantic search, automated text analysis, and LLM-assisted workflows, while integrating REST APIs, authentication, payments, and cloud storage into production-ready applications. I bring a practical mindset—turning AI outputs into usable business workflows—while continuously optimizing reliability, performance, and scalability.
