Implemented Multitenancy with Postgres RLS: Designed and implemented multi-tenancy using Postgres Row Level Security (RLS) within the application, including writing RLS policies and utilizing triggers. This ensured data isolation for different tenants and improved overall security posture. Additionally, migrated conversation history data from MySQL to Postgres without any downtime. Redesigned and implemented new high-availability, low-latency services for analytics,conversation contextual and feedback management, while splitting a legacy monolithic application into three microservices for improved performance, scalability, maintainability, and code clarity. Led data migration activity of around 500 GB from Cassandra to MySQL without any downtime. This involved application level code change. Designed a reusable Integration Framework in Spring Boot to streamline integrations and testing with various third party ticketing systems. This framework achieved an impressive 80% reduction in integration time, enabling faster development cycles and improved efficiency Application Level monitoring by writing AWS Cloudwatch metrics and datadog monitors and dashboard Reduced on-call tickets by 30% by fixing the root cause of recurring issues. Implemented a Rule-Based Engine with Decision Trees: Developed a system to automate decision-making based on user and system events. This approach facilitates the creation of complex logic flows that are clear, maintainable, and adaptable, enabling efficient rule management.

Led the design and development of a comprehensive Developer Portal, a one-stop shop for Payments API access and experimentation, facilitating API integration and onboarding,enabling Airtel Money to acquire 150+ partners to date. Responsibilities included HLD modifications, LLD design (ER diagrams, Sequence Diagrams, DB Diagrams) Architected and Built User Service from scratch, providing the core backend functionality and data storage for all user interactions.This included: SAML SSO Module with LDAP Integration: Implemented a SAML-based Single Sign-On (SSO) module for seamless organization user access and Integrated LDAP for centralized user management. Multi-Factor Authentication (MFA): Designed and implemented an OAuth-based authentication module with OTP support (Google Authenticator) for enhanced security. Scalable Login System: Developed a flexible login system supporting three methods: User ID/Password (OAuth), OTP, and Shadow Login - where a call center representative can login on behalf of a customer(OAuth + SAML). Spearheaded the development of an initial UI for the Developer Portal, fostering rapid learning and implementation of new technologies within a tight timeframe. Delivered several ad-hoc features across various services, including IP Whitelisting and a Redis-based scheduler, demonstrating adaptability and problem-solving skills Continuous Improvement: Actively contributed to Proof-of-Concepts and implementations (Hashicorp Consul, Consul Replicate, Keycloak) and spearheaded the development of a central configuration management system using Consul and Spring Cloud Config. Wrote Queries on Grafana and Prometheus for application level monitoring. Regularly conducted code reviews and mentored junior developers, fostering a culture of quality code and collaboration within the team.

Optimized Hotel Data Processing: Implemented innovative filtering strategies in the Offline Tie-Breaking Service, achieving a 25% reduction in processing time. This significantly improved data ingestion efficiency. Enhanced Video Search (COVID-19): Designed and implemented an Online Tie-Breaking Strategy for videos on HotStore, enabling efficient tagging and search for COVID-19 related content. Executed various ad-hoc features in Node.js and Java, including adding hotel and room filters, and an Admin Portal priority feature. Demonstrated strong adaptability and ability to deliver on diverse requirements.

Enhanced User Experience: Designed and implemented Vanity URL and RESTful Compliance features based on client requirements, improving user experience and streamlining data access. Improved Server Reliability: Implemented Graceful Shutdown for the Jetty REST server and MVIS Connection Manager, ensuring a smooth application shutdown process based on user-defined timers. Drove best engineering practices by promoting static code analysis, Code Reviews & CI/CD Automation. Promoting unit testing and code coverage checks: Increased unit test coverage to 65%, leading to fewer bugs and higher code quality.

Veritas Resiliency Platform : Designed and implemented APIs to display comprehensive network information across cloud and VCenter Data Centers (on-premises and remote). This improved network monitoring and troubleshooting capabilities. Developed a reusable validation framework, reducing development time and ensuring data integrity across various services. VeloCloud & VCenter Expertise: Collaborated in an 8-member team to create a VCenter plugin for VeloCloud clients. Additionally, single-handedly implemented the Service Manager Service(microservice), managed the installer, and provided installation and support for ESXi servers and VCenter Server. OpenDayLight (SDN-NFV) Contributions: Actively participated in the OpenDayLight open-source project. Gained deep understanding of its components and implemented a northbound application for OpenFlow switch configuration. Successfully delivered a proof-of-concept (POC) for a southbound plugin and service function chaining using Docker containers and OpenFlow switches.
