Senior Product Manager - Customer EngagementWorldremit Nov 2019 - Aug 2021London, England, GbLed the Customer Help product group, the product teams responsible for driving a massive reduction in contact rate, bringing it from an all-time high early in the global Covid lockdown to the lowest level it had been in 2 years. Bringing the contact rate under control was key in allowing the company to achieve its profitability targets for the year, and we had to report results on a weekly basis to the CPO, COO, and CEO of the company.While leading Customer Help, I built a strong working relationship between Customer Service and Product, which had historically been strained. Led cross-functional standups where we got all teams to understand and focus on metrics, and initiated and executed cross-functional initiatives which allowed us to drive the level of impact we had on contact rate.Expanded from leading the Customer Help group to leading the Customer Engagement group, with four product teams responsible for increasing customer loyalty, communicating about transfers, and ensuring they can get the right help when needed.Line managed a team of five Product Managers and Business Analysts, onboarding four of them remotely.Played a significant role in interviewing and hiring as we added 15 product managers to the team.Led the launch of Bill Payments for India - the first new payment type that had been launched in over a year. -
Senior Data Product ManagerGlobal App Testing Apr 2019 - Oct 2019London, Greater London, GbTransformed a siloed research and development team with no visibility across the business into a high-performing cross functional-team within the wider product organisation, with transparency across the business about projects and their impactDefined a strategic direction for the team based on R&D projects that had been completed, extensive discussions with senior company stakeholders, analysis of customer feedback and competitive research. Presented this strategic vision in an Amazon-style press release to build an understanding of the direction we could go. This resulted in a major shift in focus for the company strategy toward building a more automated and scalable productBuilt out a more detailed plan around achieving the high-level scalable product, highlighting the different areas of focus that could be looked at, and the dependencies that likely existedIn selecting focusses for quarterly work I balanced long-term strategic direction with a short-term need to address pressing customer problems, prioritising a radical change toward improving test creation process rather than automation of test execution (which was what the founders initially believed we should focus on), delivering the first major change to this process since the product was built and massively reducing the time and effort required from customers in this processPushed for my role to be more strategic and as a result, pushed the product organisation toward taking a longer-term view on work rather than primarily being reactive and driven by desires of the foundersEvaluated, selected, and implemented BI vendor for the company -
