Java Full Stack Developer Jul 2024 - Present

PNC Financial Services - Phoenix, AZ

● Spearheaded the design and delivery of cloud-native Spring Boot microservices powering loan origination and customer servicing platforms, enabling reliable, high-throughput transaction processing in a distributed banking ecosystem.

● Engineered robust React single-page applications using Redux and React Query to deliver highly responsive, state-driven user experiences for internal financial users.

● Established enterprise-grade API security by implementing Spring Security with OAuth2, JWT, and mTLS, ensuring compliance with strict banking and regulatory standards.

● Architected and exposed well-governed RESTful and GraphQL APIs with standardized error handling, versioning strategy, and resilience patterns to support mobile and web banking channels.

● Drove the modernization of legacy applications by leading the transition to Docker, Kubernetes, and OpenShift based microservices, significantly improving deployment consistency and environment scalability.

● Designed and maintained AWS infrastructure (EC2, S3, RDS, EKS) with auto-scaling, and automated failover strategies to ensure high availability and fault-tolerant application deployments in production environments.

● Optimized system performance through Redis caching, Apache Cassandra, connection pooling, and advanced SQL tuning, reducing average response latency by nearly 25% across high-traffic service endpoints.

● Built and matured end-to-end CI/CD pipelines using Jenkins, GitHub Actions, and Terraform, cutting release cycle time by nearly 30% and enabling fully automated, repeatable deployments across environments.

● Strengthened platform observability by integrating centralized logging (ELK), Prometheus metrics, and Grafana dashboards, improving production visibility and incident response readiness.

● Accelerated development productivity by leveraging GitHub Copilot and GenAI-assisted workflows for code generation, refactoring, and unit test scaffolding.

● Acted as a technical mentor and go-to resource for junior engineers, driving adoption of clean architecture, coding standards, and microservices best practices.

Java Backend Developer Apr 2021 - Jul 2023

Target - Hyderabad, India

● Engineered core Warehouse Management System (WMS) backend services using Java 17 and Spring Boot, supporting high-throughput inventory reservation, allocation, and fulfillment workflows across multiple distribution centers.

● Designed idempotent REST APIs for order picking, putaway, and replenishment processes, ensuring reliable processing under high concurrency conditions.

● Implemented event-driven inventory pipelines with Apache Kafka, enabling asynchronous stock adjustments and reducing tight coupling between WMS and upstream order management systems.

● Developed Spring Batch jobs for nightly inventory reconciliation and bulk shipment processing, handling thousands of SKU-level records and improving data consistency between warehouse and enterprise systems.

● Optimized PostgreSQL query performance through execution plan analysis, partitioning strategies, and index tuning to handle large SKU-level transaction volumes.

● Built distributed locking and caching strategies using Redis to prevent inventory oversell scenarios during parallel fulfillment operations.

● Containerized backend services with Docker and deployed to Kubernetes, configuring resource limits and autoscaling policies for warehouse workload patterns.

● Implemented resilience patterns such as retry, timeout, circuit breaker using Spring ecosystem tools to improve fault tolerance of downstream warehouse integrations.

● Partnered with warehouse operations teams to translate wave planning, pick-pack-ship, and location management requirements into scalable backend service designs.

● Strengthened platform observability through structured logging, correlation IDs, and Splunk dashboards, significantly reducing time to diagnose fulfillment discrepancies. Java Full Stack Developer Jan 2019 - Mar 2021

Metlife - Hyderabad, India

● Developed policy servicing and claims processing microservices using Spring Boot and Spring Cloud, enabling modular and independently deployable insurance workflows.

● Engineered dynamic Angular-based customer servicing portals using TypeScript and component-driven architecture, improving agent productivity and reducing manual processing time.

● Implemented secure API integrations between internal systems and third-party partners using REST and OAuth2, ensuring compliance with enterprise security standards.

● Leveraged Apache Kafka for asynchronous communication between underwriting, billing, and claims services, improving system resilience and decoupling legacy dependencies.

● Designed and optimized complex data access layers using Oracle and MongoDB, supporting both transactional and document-based insurance data models.

● Built and deployed containerized services using Docker and Kubernetes on AWS, improving environment consistency and enabling elastic scaling during peak claim cycles.

● Integrated SonarQube quality gates and automated testing into the CI/CD pipeline, enabling faster and more confident releases by catching defects early in the development cycle.

● Collaborated closely with business analysts and product owners to translate regulatory and compliance requirements into scalable technical solutions.

● Enhanced API reliability by implementing circuit breakers and resilience patterns to handle downstream service failures gracefully.
