  • Designed and implemented microservices architecture using Spring Boot, Gradle, and GraphQL, ensuring modularity and maintainability across multiple enterprise systems.
  • Led the OMPS (Operational Messaging Profile System) modernization by integrating HR and claims microservices with attribute-based filtering and dynamic models for Composer types (PC/CLM, PC/PS).
  • Built and optimized Spring Batch jobs for worker cleanup, integrating with HRServiceClient for inactive record deletion and automated email report generation.
  • Implemented secure credential management via Conjur and OpenShift secrets using Spring Security and ID claim providers for service account authentication.
  • Developed Kafka producers and consumers with Avro serialization for real-time data streaming, ensuring exactly-once delivery semantics.
  • Automated data ingestion pipelines from legacy systems into Snowflake using AWS Glue, Lambda, and S3 as part of the Capital One data migration program.
  • Built PySpark ETL workflows for cleansing and transforming DFS datasets, integrating with Capital One’s internal tools (PDS, XDS, and D2A).
  • Tuned HikariCP connection pools and optimized Oracle queries to eliminate 503/504 timeout issues in high-throughput production environments.
  • Developed RESTful APIs to serve metadata, profile data, and HR attributes, implementing caching and pagination for better performance.
  • Created and maintained CI/CD pipelines in GitLab and Jenkins, including quality gates with Checkstyle, SpotBugs, and SonarQube integration.
  • Monitored microservice health and performance using AppDynamics, Splunk, and ELK dashboards, and implemented proactive alerting mechanisms.
  • Managed Kubernetes/OpenShift deployments, using HPA and ConfigMaps for scaling and configuration management of production pods.
  • Collaborated cross-functionally with onshore and offshore teams, conducting nightly Scrum syncs to resolve blockers and ensure sprint alignment.
  • Designed and documented data lineage and quality dashboards for migrated datasets using Pandas and Excel automation scripts.
  • Integrated Hazelcast distributed maps for low-latency in-memory caching and improved response times across high-traffic services.

06.2022 - 06.2024
  • Designed high-security gateways to handle all inbound/outbound API calls, enforcing OAuth2, JWT, and role-based authentication for Citi’s internal and external banking partners.
  • Designed modular, independent services with Spring Boot and Spring Cloud components — implementing service discovery, load balancing, and fault tolerance.
  • Created a proof of concept for automated KYC (Know Your Customer) verification using:
    Tesseract OCR / Google Vision API for document scanning
    Azure Face API / OpenCV for facial recognition
    Integrated output with Citi’s core banking API for customer creation
  • Built a secure, centralized API registry where internal clients could register, manage, and access APIs with proper RBAC (Role-Based Access Control) and API key generation workflows.
  • Migrated monolithic modules into event-driven microservices leveraging Apache Kafka for asynchronous message communication and high-volume transaction handling.
  • Implemented GraphQL endpoints to eliminate over-fetching issues and REST APIs to bridge communication between front-end (AngularJS airline portal) and backend systems.
  • Engineered schema design in MongoDB, MySQL, and Amazon S3 to efficiently manage structured/unstructured data.
    Optimized PL/SQL and MySQL stored procedures for faster financial transaction execution.
  • Built AWS Lambda functions for event-driven automation and established CI/CD pipelines using Jenkins, CodePipeline, and Kubernetes Helm charts for auto-deployment.
