I architect & deliver complex Mendix ecosystems - from blank canvas to successful go-live.

With Advanced Mendix certification and 4+ years of hands-on delivery, I specialize in translating high-level business goals into scalable low-code blueprints. Currently pursuing Mendix Expert certification. My work spans manufacturing, public sector, healthcare, environmental services, gaming, maritime, and corporate services — always meeting strict performance, privacy, and audit requirements.

Beyond Mendix, I build with Java, JavaScript/React, Dart/Flutter, and SQL — giving me the depth to extend any platform with custom actions, connectors, and integrations. Shipped consumer apps with 300K+ downloads and a 4.8-star rating, integrated AI APIs from OpenAI to Anthropic, fine-tuned LLMs, and run paid acquisition across Google Ads, Apple Search Ads, and TikTok. Active contributor on the Mendix Community forum.
