Top SchoolAndre Cronje is a serial blockchain architect and founder with eight years of hands-on experience building DeFi infrastructure and high-scale financial systems. Based in New York, he has led and advised multiple projects including yearn.finance—where he architected yield-optimization products—and contributed front-end enhancements to the well-known iearn-finance web repository. His background spans roles from CTO and Head of Technology in fintech and telecom to technical advisories for major foundations like Fantom and Fusion, blending product-level vision with low-level engineering.

Notably, he pairs formal legal training (LLB) with deep technical craft, a combination that helps him navigate the regulatory and architectural complexities of crypto finance.
