Responsibility

Product Lead

As a seasoned Senior UX Designer and Product Lead, I've had the privilege of working on groundbreaking projects like Reuters' HighQ AI and Document Intelligence. During my tenure with Reuters, I facilitated the end-to-end development of an AI-driven contract analysis tool tailored for legal professionals. This role demanded a deep understanding of the legal landscape and an ability to harness technology to streamline complex workflows and empowering lawyers to identify key risks and obligations more efficiently. Moreover, I led the creation of intuitive user interfaces, leveraging my UX expertise to enhance user experiences and ensure seamless communication of complex legal concepts. My contributions to HighQ, particularly in areas such as document automation, workflow optimisation, and secure data handling, significantly improved operational efficiency, reduced risk, and ultimately elevated client service standards. An 8 hour contract review process was reduced to 2 hours, time savings of at least 72%.

Challenge

Legal teams spend countless hours manually reviewing lengthy contracts. The process is time-consuming, prone to human error, and delays decision-making.
