Minal – Spring Boot, Java, Spring

A high-volume financial transaction processing platform supporting banking and Securities restrictions workflows.

• Led back-end modernization from tightly coupled synchronous processing toward scalable microservices and event-driven architecture.
• Redesigned critical transaction flows using Kafka, reducing end-to-end processing latency by approximately 80%.
• Designed REST APIs and OpenAPI contracts for upstream and downstream integrations.
• Implemented idempotency and duplicate-processing protection for financial transactions.
• Designed Kafka consumer groups and asynchronous processing workflows for high-volume transaction workloads.
• Implemented transactional processing patterns to maintain consistency between database state and published events.
• Improved CI/CD using Jenkins, Docker, and OpenShift.
• Participated in production troubleshooting, performance optimization, and root-cause analysis.
• Mentored junior engineers on Spring Boot, Kafka, API design, and distributed-system patterns.
• Supported systems processing millions of transactions daily with high availability.

An enterprise banking platform responsible for processing and integrating international financial transactions across banking and custody environments.

• Migrated legacy back-end application to a microservice-based, scalable application for high-volume SWIFT message payment processing.
• Worked with SWIFT MT/MX messaging and financial transaction workflows.
• Designed REST APIs for integration between banking systems and downstream services.
• Implemented validation and transaction-state management across multi-step payment workflows.
• Used Kafka for asynchronous message processing and decoupling of downstream systems.
• Implemented error handling, retry mechanisms, and controlled failure processing.
• Investigated and resolved production issues affecting transaction processing and system integrations.
• Collaborated with business analysts, QA, product teams, and other engineering teams.
• Participated in technical design, code reviews, and production releases.
• Improved reliability and maintainability of legacy financial-processing components through incremental modernization.

An enterprise API platform that enables secure integration between internal banking applications, external partners, and downstream financial services.

• Designed and developed scalable REST APIs using Java and Spring Boot.
• Created API contracts using OpenAPI and promoted contract-first development.
• Worked with Apigee API Gateway for API management, routing, security, and traffic controls, rate-limit/burst limit setup.
• Implemented authentication and authorization patterns for secure enterprise integrations.
• Designed APIs supporting multiple upstream and downstream consumers.
• Introduced reusable API integration patterns that reduced partner onboarding effort.
• Integrated synchronous REST APIs with asynchronous Kafka-based workflows.
• Improved API reliability through validation, error handling, timeout, and retry strategies.
• Collaborated with architecture, security, QA, and product teams.
• Participated in API design reviews and established development standards for backend services.
