Engineering reliable IT at enterprise scale
I am an IT Engineer with more than five years of hands-on experience in London's fast-moving fintech sector. I lead the administration, deployment, and integration of the industry's leading SaaS platforms, and I take a central role in connecting them cleanly into existing systems, from identity and access to networking, mail, and device management.
In fintech, priorities shift in minutes. Drawing on years of experience, I combine disciplined time management with deep technical knowledge to stay calm and effective under pressure. I have invested heavily in interpersonal awareness and crisis-management skills, and I work to a high standard of GDPR-aware, security-first practice across everything I deliver.
I grew up in a feedback-driven culture, focusing for years on competency-based development with the support of HR teams and managers, and always putting the feedback I received into practice. The experience I gained at Apple and the companies that followed taught me to mentor teammates and contribute to their growth. I value individual achievement, but I know that moving as one team is what helps us get a little better every day.
