I am currently an executive at Revolut with over 8 years of experience focusing on building decision-making systems, end-to-end process optimisation, platform development, and automation. Part of my scope has been designing and building internal products key to Revolut success, reporting to the founder and CEO. Part of my scope has been building and leading teams, both directly and at department level, and identifying and nurturing talent. I believe in ownership, empowerment, honouring agreements, insight, metrics, methodicalness, testing and system design, using the right tool for the job, and moving fast. I love making impact, achieving more as a capable team, and finding and building elegant solutions to complex problems. For the core of what I do, I do what I can, so keep a whole heart, have no regrets, and sleep well.
