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.

• Developed and deployed a robust WebSocket-based chat and notification service, leveraging advanced web socket protocols for real-time communication. • Conducted performance optimizations on the Backend (BE) API, introducing a Lambda wrapper to seamlessly interface between AWS AppSync and Backend microservices. This strategic implementation effectively mitigated potential security vulnerabilities. • Demonstrated proficiency in a diverse array of AWS services, encompassing SQS (Simple Queue Service), SNS (Simple Notification Service), RDS (Relational Database Service), AppSync, Lambda, and AppRunner, among others. • Engineered a sophisticated algorithm to discern unique violations, systematically processing and identifying anomalies within data pushed to the SQS queue by the AI core engine. • Enforced Role-Based Access Control (RBAC), ensuring a granular and secure access management system within the software architecture. This implementation contributes to a robust security posture and controlled access to critical functionalities.

• Engineered a Recommendation Service employing the Haversine formula and interfacing with various REST APIs for product data, all meticulously implemented within the Spring Boot framework. This approach ensures precise geospatial calculations and seamless integration with external data sources. • Delved into the intricacies of multiple AWS services, including AWS AppSync for facilitating real-time data synchronization, Lambda for serverless compute, and both RDS (Relational Database Service) and DynamoDB for efficient and scalable data storage. This comprehensive AWS utilization optimizes the overall functionality and scalability of the system. • Spearheaded the development of GraphQL queries, mutations, and subscriptions as integral components of a client project. This involved crafting efficient and tailored data retrieval mechanisms, leveraging the expressive power of GraphQL to enhance data fetching capabilities and streamline client-server interactions.
