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.

Instrumental role as owner of multiple, frequently used microservices. Conducted knowledge transfer sessions while promoting better understanding of the system and coordinating design decisions.

▪ Initiated new project, including design, proof of concept, and development of new feature to send documents on customer behavior to client for e-signing; completed development in one month for release.

▪ Significantly raised optimization levels through designed, implemented proof of concept, and developed DocuSign integration microservice allowing users to send e-sign documents to clients within the platform with user-customized tabs.

▪ Improved performance tuning for trip generation; analyzed all aircrafts available for user and calculating trip data.

Gained valuable experience implementing new business requirements, collaborating with QA teams, and solving targeted defects.

▪ Supported migration from monolithic Java application to microservices Java application.
