PROFESSIONAL EXPERIENCE

Software Engineer Mizuho Americas — New York, NY Jan 2025 – Present

•Built microservices for financial transaction processing using Spring Boot, Spring MVC, and Spring Cloud, implemented service discovery with Eureka and configured Spring Cloud Gateway for routing requests across distributed services.

•Containerized Java applications using Docker and deployed to AWS ECS (Elastic Container Service), configured AWS RDS for relational database management and AWS S3 for document storage, integrated CI/CD pipelines with Jenkins for automated build and deployment workflows.

•Developed event-driven transaction processing pipeline using Apache Kafka for real-time financial data streaming, implemented producer-consumer patterns for asynchronous message processing and event handling across microservices.

•Integrated Redis for distributed caching of frequently accessed reference data and session management, optimized database queries and indexing strategies to reduce redundant calls and improve API response times.

•Built AI-powered document analysis features using Spring AI framework to extract and classify data from financial documents, integrated OpenAI API for automated text processing and data extraction in compliance workflows.

•Implemented OAuth2-based authentication and JWT token validation for securing internal REST APIs, followed security best practices for handling sensitive financial data and adhered to PCI-DSS compliance requirements.

•Configured AWS CloudWatch for application monitoring, logging, and alerting, troubleshot production issues and performed root cause analysis for system failures and performance bottlenecks.

Software Engineer OpenText — Bengaluru, India Apr 2021 – Jan 2024

•Developed and maintained a global enterprise-scale Java full-stack web application for a B2B supply chain and order management platform, serving 700+ enterprise customers and processing 16+ billion transactions annually across mission-critical production systems with complex business workflows and multi-tenant architecture.

•Built and maintained server-rendered frontend pages using JSP, HTML5, CSS3, JavaScript, and AJAX, integrated React component libraries within JSP templates to progressively modernize the UI, enhancing interactivity and user experience without requiring a full frontend rewrite.

•Developed backend services and business logic using Java, Spring Framework, and Spring MVC with Hibernate ORM, supporting complex supply chain workflows including order processing, fulfillment, inventory updates, and exception handling, designed and built RESTful APIs to expose endpoints for electronic Invoice and Advance Ship Notice (ASN) document processing, enabling secure and standardized B2B EDI data exchange between trading partners.

•Redesigned a synchronous large-scale report generation framework into an asynchronous processing pipeline using message queuing (Kafka), decoupling report execution from the request-response cycle via a producer-consumer architecture and reducing end-user wait time by approximately 90%.

•Designed PL-SQL stored procedures, cursors, and scripts for large-scale data migration, data cleanup, and transaction management, ensuring referential integrity and consistency across relational database schemas.

•Performed database query tuning and indexing optimization using composite indexes and execution plan analysis, reducing query execution time and memory utilization, implemented Redis for application-level metadata caching, eliminating redundant database calls and improving response times for frequently accessed reference data.

•Managed end-to-end CI/CD pipelines using Jenkins and Ansible, automating build, test, and deployment workflows across development, staging, and production environments, served as Release Manager for 15+ major production releases, coordinating cross-functional development, QA, and operations teams to ensure on-schedule deployments with minimal downtime.

•Remediated vulnerabilities identified through Fortify SAST and Black Duck SCA scans, resolving SQL injection, XSS, insecure deserialization, and vulnerable third-party dependencies, hardened the application using Spring Security to mitigate OWASP Top 10 threats including authentication bypass, session fixation, CSRF, and insecure HTTP headers, enforced secure coding standards through peer code reviews.

•Collaborated with product managers, QA engineers, and business stakeholders in an Agile/Scrum environment across sprint planning, backlog grooming, and retrospectives, translated business requirements into technical specifications and resolved production incidents through root cause analysis and hotfix delivery.

•Led the modernization of NBT (Network Based Translation), a legacy EDI translation application handling EDI-to-non-EDI conversion for B2B supply chain communication, upgraded from Java 6 to Java 17, migrated to the corresponding Apache Tomcat version and updated all dependent libraries, and redeployed on RHEL 8.8, eliminating end-of-life infrastructure dependencies and reducing operational and licensing costs.

Software Engineer Intern OpenText — Hyderabad, India Dec 2020 – Apr 2021

•Automated 20+ functional and regression test cases using Java, Selenium, and TestNG for the OpenText Magellan product, improving test coverage and reducing manual testing effort.

•Developed and executed test scripts to validate application functionality, performance, and reliability across multiple modules, identified, documented, and tracked software defects through to resolution.
