• Developed tech spec, identified deltas between offline and online onboarding flows & analysed multiple routes for merchant onboarding flows. Using all this information to develop an app for migration of existing merchant (successfully migrated around 1.5K+ merchants) data efficiently to enhance user experience and to support payment processing via an omni channel platform. The app thus developed can be integrated with various onboarding flows to initiate realtime migration for the merchants as well.
• In addition to this, worked on banking integrations for procurement of sub merchant config and onboarded multiple PGs on the system.
• Last but not the least, refactored post processing flows for omni channel merchants.
