full stack developer

I build complete platforms using Python (Django) and React, alongside other technologies to best suit the task at hand. Over the past 16 years, I have built or significantly contributed to numerous web-based, data-driven environments. These experiences have equipped me with the skills and insights to empower my clients to leverage the incredible opportunities provided by open-source technologies, giving them a running start in developing their platforms.

I work for an hourly rate from my office in Heemstede (Amsterdam area, The Netherlands).

A selection of projects I've delivered:

• Developing an asset management system for Key Agency to streamline content rollout processes for a leading motorbike manufacturer's product configurator.
• Creating an extensible dialog editor, integrating various NLP models and APIs and rebuilding a chatbot state machine architecture for Joboti (now Textkernel).
• Building MataCSM, an enterprise security monitoring system to proactively identify and mitigate security threats.
• Implementing a data driven innovation adoption management system called Implementation Analyzer for Implementation IQ
