I like patterns and building systems that scale.
Currently working on finance, data, and automation.
I spent my early years in finance, starting at PwC and later working in-house in operating roles in VC-backed companies. I was a Controller at Reckitt Benckiser and then Finance Manager at inSided (acquired by Gainsight). After three years, I moved on to Catawiki as a Finance Business Partner and finally as Interim Strategic Finance at Contentoo.
Across these roles, I worked closely with founders and leadership teams, building financial models, reporting, and internal processes in fast-growing environments. Over time, I became more interested in building the systems behind the work. I became interested in automating processes, encoding logic, and reducing manual effort, rather than operating them manually.
Today, I focus on designing and building tools and systems at the intersection of finance, data, and software, with an emphasis on leverage, clarity, and long-term scalability.
