EXPERIENCE

Capital one MO, USA

Java Developer Feb 2025 – Current

• Built and implemented scalable Microservices using Java 17, Spring Boot, REST APIs for processing internal account adjustments correcting workflows ensuring data accuracy and secure transaction processing.

• Developed web interfaces using Angular and API contracts, integrated RESTful endpoints into Angular components using HTTPClient, ensuring smooth data exchange and responsive UI behavior.

• Designed Kafka-based event-driven flows by configuring producers and consumers across 5+ services, Kafka was used to broadcast adjustment actions.

• Implemented message serialization (Avro/JSON) and built custom Kafka listener logic with retries and error queues to maintain reliability during spikes and partial failures.

• Led PostgreSQL performance tuning by redesigning key schema structures, optimizing slow-running queries, and adding indexes, improving system response time.

• Rolled out production-ready features to AWS (EC2, S3, RDS) integrated AWS Lambda to trigger audit logging and email notifications based on account adjustment events.

• Monitored production health using Dynatrace, setting up dashboards to trace slow endpoints and managed CI/CD pipelines using GitHub Actions and Jenkins.

Spectrum MO, USA

Java Developer Jan 2024 – Dec 2024

• Designed and built scalable microservice for a real-time customer refund platform using Java 11 and Spring Boot, automating over 30 business rules.

• Built custom inter-service communication handlers using Feign Clients for efficient and fault-tolerant REST API calls between microservices.

• Enhanced consumer error-handling logic using retry mechanisms and dead-letter topics to maintain message integrity under high-load conditions.

• Consumed Kafka messages (ticket updates, network events) to re-trigger refund evaluations and auto-adjust credits in real time.

• Secured application data flows by developing RESTful APIs with token-based access control, including implementations of Spring Security and JWT.

• Optimized data access for refund calculations using Spring Data JPA and Hibernate with Oracle database, reducing transaction processing latency by 400 milliseconds through refined query patterns.

• Containerized applications with Docker and deployed to AWS (EC2, RDS) increasing system scalability and reducing deployment overhead.

• Utilized Postman for eligibility checks, and validated flows and integration tests in JUnit and Mockito. Wipro Ltd India

Java Developer Nov 2020 – Dec 2022

• Rebuilt backend services using Java 17, Spring Boot, and RESTful APIs, modernizing business-critical modules and enabling cleaner integration with new Endur system.

• Utilized the Spring ecosystem (combining Spring Boot, MVC, Data JPA, Security, and AOP) across backend layers in trade validation and data reconciliation modules.

• Migrated database from MS SQL Server to MySQL, rewriting stored procedures, optimizing queries, and ensuring full data consistency post-migration.

• Enhanced XML-based Spring configurations to annotation-driven Spring Boot modules in trade validation and batch scheduling services, reducing bootstrapping time by 40%.

• Refactored legacy code by introducing Java 8+ features like Lambda expressions and Streams API, improving readability and maintainability.

• Implemented Spring AOP across backend services within the trade validation and risk calculation modules to handle logging, exception tracing, and execution timing, improving observability during UAT and production support.

• Integrated structured logging via Log4J, enabling detailed application logging and error tracking, faster incident resolution and better system observability. TECHNICAL SKILLS
