Jenius Bank — Associate Software Developer, Phoenix, AZ Oct 2023 – Present

• Designed and developed Kotlin-based gRPC microservices using coroutines for asynchronous, non-blocking processing in a high-throughput banking platform.

• Built and maintained scalable REST APIs using Kotlin and Spring Boot, enabling seamless integration between REST and gRPC services.

• Integrated external credit and fraud vendor APIs (TransUnion, Equifax, LexisNexis, FIS) to support real-time underwriting and fraud decisioning workflows.

• Designed scalable data persistence layers using MongoDB and Azure Cosmos DB for high-volume transactional processing.

• Reduced external API response latency by 90% by implementing Redis caching for frequently accessed vendor responses.

• Developed fault-tolerant Spring Batch jobs with pagination to reliably process large transactional datasets.

• Containerized microservices using Docker and deployed on Azure Kubernetes Service (AKS); secured secrets and configura- tions using Azure Key Vault and Azure App Configuration across environments.

• Implemented event-driven, cross-cloud data pipelines by publishing streams from Azure services to GCP Data Lake using Google Pub/Sub.

• Integrated machine-learning-based fraud prediction services into backend workflows to enhance fraud detection accuracy.

• Conducted performance and load testing using JMeter to validate system scalability under peak traffic conditions.

• Built high-performance Python FastAPI services and automation scripts using Pandas and NumPy for asynchronous data processing.

• Implemented CI/CD pipelines using Azure DevOps and Jenkins to automate build, test, and deployment processes.

• Monitored production systems using Splunk dashboards, OpenTelemetry distributed tracing, and OpenSearch log analysis to ensure reliability and observability.

Capital-Soft Tech Inc — Java Developer, Texas, US May 2023 – Sep 2023

• Developed Spring Boot microservices using object-oriented design patterns (Singleton, Factory, Strategy, Adapter).

• Applied TDD practices using JUnit and Mockito, achieving 85%+ unit test coverage.

• Deployed cloud-native services on Google Cloud Platform using GKE, Cloud Run, Cloud SQL, and Pub/Sub.

• Built React.js frontend components using JavaScript/TypeScript with Redux and Context API, integrated with Spring Boot REST APIs.

Innovation Technology Ecom — Associate Software Developer, India Jan 2020 – Dec 2021

• Built event-driven microservices using Apache Kafka for asynchronous communication between distributed systems.

• Designed and implemented ORM layers using JPA and Hibernate for efficient data access.

• Secured REST APIs using JWT and OAuth 2.0, and implemented asynchronous processing using Spring @Async and CompletableFuture.

• Containerized applications using Docker and deployed them on AWS EKS with load balancing and auto-scaling.

• Developed Angular components using TypeScript and integrated them with Spring Boot backend APIs.

• Automated build and deployment workflows using Jenkins and Git-based CI/CD pipelines. Education
