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.
Experience you can measure
Five years owning IT operations end to end in London fintech — identity, networking, devices and the SaaS stack that ties it all together.
Experience in brief
Technical support, customer relationships, operations and IT, in my own words.
My career started in the field, working on engagement initiatives and then planning locations, communication and logistics for a 120-person team. Those early years taught me to coordinate people and resources under real constraints, and to communicate clearly with every stakeholder involved.
I then spent nearly seven years in technical support and leadership roles, delivering consistently high customer satisfaction, coaching colleagues and growing through leadership development programs. Alongside that, I owned customer relationships and new business development in e-commerce, building processes that improved retention and client satisfaction.
Today I bring all of this into IT engineering in London's fintech sector: identity and access, networking, device management and the SaaS stack that ties it together. I also built a native ITSM application on Claude Managed Agents and Cloudflare, which cut ticket resolution time by 80% and raised automated ticket resolution by 60%. The thread running through every role is the same: stay calm under pressure, listen first, and build things that people can rely on.
