Designing and implementing new credit card products, both secured card and multi card, enabling provision, with minimal risk, of cards to customers not qualified for ordinary credit cards.
▪ Facilitated breaking monolithic service by moving features to other microservices and creating new microservice when needed.
▪ Drove refactoring of lookup flow, modified data loading mechanism from recycling all data, to increment load, then message driven – improved SQL query and increase query time, resulting a loading process taking less than half an hour to finish.
▪ Led design and implementation of new products including, pre-qualification, secured card, multi card, built on previous
model of only one credit card product.
▪ Continuously increased credit card bookings from 600k to 2M card holders in a year and a half, raising the booking rate by
50%+.
▪ Established integration tests for existing and new projects, including integration automation using Selenium and Jenkins.
▪ Built AB testing, working closely with the data product teams to develop AB tests, and successfully increase submission rate.
