Summary
Senior Software Developer with extensive experience building and maintaining cloud-native, distributed backend systems across banking, healthcare, and enterprise environments. I specialize in developing microservices with Java, Spring Boot, Python, and .NET, and deploying them on AWS EKS and Azure AKS using Docker, Helm, and automated CI/CD pipelines. My work spans real-time payment processing, fraud evaluation, document ingestion, and provider workflow automation, often using event-driven patterns with Kafka, EventBridge, SQS, Redis, and serverless components to achieve high throughput, resilience, and low latency. I focus on clean architectural practices well-structured controller, service, repository, configuration, and security layers paired with reliable REST API design, OAuth2/JWT authentication, OpenAPI documentation, and strong test coverage using JUnit, Mockito, Postman, and integration suites. I am experienced across relational and NoSQL databases, including PostgreSQL, Oracle, SQL Server, DynamoDB, and MongoDB, and bring a strong understanding of schema design, query optimization, and data modeling. I also emphasize observability and operational readiness, using CloudWatch, ELK, structured logging, and OpenTelemetry to maintain visibility, diagnose issues quickly, and keep production systems stable under load.

Work History
Senior Software Developer
Fifth Third Bank
02.2023 - Current
- Developed distributed real-time payment microservices using Java, Spring Boot, and Python to support ACH, Wire, and RTP workflows with low latency and strict compliance.
- Implemented OAuth2 and JWT authentication for internal and external APIs, integrating API Gateway for secure routing, throttling, validation, and service-to-service communication.
- Built event-driven pipelines using Kafka and EventBridge to enable resilient, idempotent transaction processing with retries, dead-letter routing, and asynchronous downstream execution.
- Built real-time Apache Flink pipelines consuming Kafka events to perform sub-second fraud evaluation, anomaly detection, and high-volume streaming payment transformations.
- Ensured microservices handled duplicate Kafka events, retries, and network failures without double-posting, making payment processing fully idempotent across distributed systems.
- Developed Lambda-based serverless components for reconciliation, notifications, fraud checks, and audit logging, storing all artifacts and exception data in KMS-encrypted S3 buckets.
- Engineered multi-database persistence using PostgreSQL, Oracle, DynamoDB, and Redis for transactional storage, configuration metadata, velocity checks, and high-performance caching.
- Deployed microservices on AWS EKS using Docker, Helm, and GitHub Actions with automated builds, static code scanning, quality gates, and blue/green release strategies.
- Implemented TDD and BDD practices using JUnit, Mockito, PyTest and Cucumber, ensuring code correctness, integration stability, and regression test reliability across payment workflows.
- Configured SonarQube quality gates to enforce code coverage, security standards, static analysis rules, and maintainability benchmarks throughout the CI/CD pipeline.
- Designed and executed comprehensive API test suites in Postman, validating request flows, response schemas, authentication rules, and regression scenarios across distributed microservices.
- Implemented Redis-based caching and rate-limit layers to accelerate payment lookups, reduce database load, support velocity checks, and deliver low-latency microservice responses.
- Built ELK-based observability with structured JSON logging, CloudWatch metrics, distributed tracing, and Elasticsearch indexing for faster incident investigation and root-cause analysis.
- Created resilient data layers with IAM-based DynamoDB access, VPC isolation, security rules, and encryption to ensure secure inter-service communication and audit compliance.
- Utilized Unix/Linux for service administration, log analysis, shell scripting, process monitoring, and deployment troubleshooting across distributed cloud-native microservice environments.
Software Developer
Cigna Healthcare
02.2021 - 12.2022
- Developed backend microservices for document ingestion, and file retrieval using Java, Spring Boot, and .NET, ensuring consistent handling of provider files, and compliance across distributed platforms.
- Developed secure RESTful APIs using Spring Boot, JWT, and RBAC to handle high-volume document requests with accurate validation, consistent responses, and reliable processing.
- Built and optimized database operations using SQL Server and Oracle by writing stored procedures, and tuning complex queries to support fast metadata lookups and high-volume document retrieval.
- Designed semi-structured data handling workflows with MongoDB and DynamoDB, flexible querying, and version tracking for provider, audit records, and compliance related submissions.
- Managed Docker-based microservices on Kubernetes, configuring autoscaling, liveness/readiness probes, and resource limits to ensure stable, high-performance workload execution under heavy load.
- Built CI/CD pipelines in Azure DevOps automating builds, testing, artifact packaging, and Azure Kubernetes Service deployments, ensuring consistent, reliable release cycles across all environment.
- Implemented extensive backend test coverage using JUnit, NUnit, xUnit, Mockito, and Postman to validate API logic, metadata rules, and interactions across multiple dependent services.
- Built AWS Lambda functions for metadata extraction and event routing, offloading pre-processing workloads and enabling efficient serverless execution during peak document intake.
- Applied OpenAPI and contract testing to validate API schemas, ensuring consistent request structures and preventing breaking changes across microservices and integration environments.
- Executed JMeter load tests to evaluate Kafka producer–consumer performance, ensuring stable event processing, low latency, and reliable microservice throughput under heavy load.
- Built Azure Functions to trigger on Blob uploads, perform lightweight file validation, extract basic metadata, and publish intake events, accelerating document workflow initialization.
- Used Prometheus and Grafana to track microservice metrics, identify ingestion latency patterns, and visualize bottlenecks, enabling faster troubleshooting and performance optimization.
- Applied TDD by writing unit tests before implementation, ensuring reliable microservice logic, reducing defects, and improving code quality through early validation cycles.
- Leveraged Redis caching for frequently accessed provider metadata, minimizing SQL/Oracle reads and significantly accelerating response times in high-volume document workflows.
- Worked in Agile Scrum teams, participating in sprint planning, refinement, daily stand-ups, and retrospectives to deliver prioritized microservice features with consistent quality.
- Integrated Kafka producers and consumers to propagate document events, ensuring reliable asynchronous communication and improved workflow visibility, across distributed microservices.
