Summary

As a seasoned Talent Acquisition Manager with over 15 years of global recruitment experience across corporate, RPO, and agency environments, I have developed a robust ability to build and lead high-performing talent acquisition functions.

My expertise lies in navigating the intricacies of talent acquisition across diverse organisational stages. I have partnered with a wide array of businesses, from early-stage startups to established enterprises, gaining deep insights into the unique challenges and opportunities that each growth phase presents.

With a strong focus on scaling startups, particularly in deep tech, AI, and, more recently, biotech, I’ve consistently delivered tailored recruitment strategies that drive results and foster innovation. Whether it’s designing processes to attract top-tier technical talent or implementing scalable solutions to support rapid growth, I am dedicated to delivering measurable value and impact.
