What I'm looking for

I seek senior HR leadership roles where I can drive strategic people initiatives, lead organizational transformation, coach leaders, and scale people functions in high-growth, mission-driven companies.

I am a Strategic Global HR Executive and Certified Executive Coach with a proven record of aligning people strategy to business objectives across technology, financial services, healthcare, SaaS, crypto, media, and retail sectors. I have led large-scale HR transformations, workforce redesigns, M&A integrations, and built high-performance people functions that scale in fast-paced, high-growth environments.

I deliver measurable impact by designing career pathways, implementing performance and engagement programs, and enabling leaders through coaching and training—generating multi-million-dollar cost savings, improving engagement and leadership effectiveness, and strengthening succession and talent pipelines globally.
