• Day-to-day responsibilities looked like building and designing payment flows, in such a way that the payment mode itself is reliable enough. Built reconciliation systems of different payment flows so neither bank nor user incurred a financial loss. or if it had incurred necessary actions could be taken in near real-time. Worked on reducing CST volume by improvising the system to smooth the end-user experience.
