• Initiated and led the development of the Cruise Portal (NextJs, Typescript, AWS), integrating Odysseus for search and booking, digitizing a previously offline process and increased revenue by 30%. played a pivotal role in its design, development, and deployment increase
• Implemented a JWT-based SSO and role-based access control (RBAC) system, which enhanced security, provided granular permissions, and streamlined user access.
• Developed and deployed a Redis-based session management and API rate-limiting system to enhance backend stability and protect against Denial of Service (DoS) attacks.
• Centralized Next.js middleware to handle authentication, RBAC, and security headers, which improved security compliance and significantly reduced code duplication.
• Reduced booking auto-cancellations by ~15% by building a timezone-aware pre-cancellation alert system using AWS Lambda, DynamoDB, and EventBridge, converting potential losses into confirmed bookings.
• Designed and implemented high-performance Booking Queue with GraphQL (AppSync), lazy loading, real-time filters reducing booking search time and boosting agent productivity.
• Architected and implemented a centralized observability pipeline by pushing logs to Kafka from Next.js and AWS Lambda functions. This enabled downstream ETL processes and empowered data-driven insights via Athena queries.
• Enhanced system monitoring and alerting by building a Grafana Dashboard on top of a time-series database. Configured SMTP and a central email service to send real-time notifications for critical events like payment alerts, new bookings, and pre-cancellation reminders.

• ExtranetLite
• Implemented a Bulk Update Feature on the ExtranetLite portal which simplified multi-level inventory management reducing inventory load & update time and improved efficiency. Integrated WebSocket for live status tracking on inventory operations. Leveraged Axios and Bootstrap to enhance responsiveness and data handling.
• Built an efficient Go application with the Fiber framework that runs at configurable intervals to retrieve essential transaction logs from AWS Glue using Athena query, stream them to Kafka, and optimally store them in S3. Reduced log storage costs by 30% through selective retention of critical logs.
• Accomplished robust security upgrades to enhance user protection on the Elite portal, implementing:
• 2-Factor Authentication: Integrated OTP-based login, resulting in an extra layer of security for user accounts.
• Password Expiry Feature: Enforced configurable password changes, ensuring regular updates to reduce security vulnerabilities.
• Horizontal Privilege Escalation Prevention: Applied permissions on backend APIs, ensuring restricted access to authorized users only.
• BookSure Engine
• Developed the microservice to optimize handling of prebook failures by creating and managing blocking rules, reducing unnecessary U-API request processing time.
• Consumed pre-book failures data through Kafka streams, created blocking rules using ETCD configuration, and pushed them to App Sync, which loads the rules into DynamoDB for proactive request blocking.
• MSE (Multi Search Engine)
• Developed a Microservice MSE that optimizes hotel searches by integrating, aggregating, and deduping responses from multiple suppliers, ensuring only the best room options are presented. Supported the implementation of Search and Prebook APIs for efficient and accurate search results.
• Implemented a sampling mechanism to block unnecessary search requests for inactive or sampled suppliers and hotels, significantly reducing search response time by 20%.
