About me

I help international professionals find, land, and negotiate sponsored roles in the UK and EU. With firsthand experience navigating visa sponsorship three times across three different employers, I understand the broken system — and I've built the solution to fix it. I'm the Co-founder of migreats, a platform combining community, job applications, and a data-driven job board into one place for international talent seeking sponsored roles. With 200+ community members and 100+ individuals supported through their sponsored career journeys, whether convincing an existing employer to sponsor or finding a new role, migreats is reshaping how international professionals navigate the UK job market. Alongside migreats, I lead Go-to-Market for the Higher Education sector at Borderless, building a compliance product that helps institutions stay UKVI-compliant and better support international students.
