Software Developer II South Bend, IN

• Designed and developed end-to-end clinical dashboards using Angular, TypeScript, and Spring Boot, integrating Solr for federated search across 200+ healthcare data sources and achieving 20 faster response times on more than one million medical records.

• Built and deployed cloud-native microservices in Kotlin and Java using Spring Boot, and a performance-critical data processing service in Rust, for healthcare data migration of over 1TB of DICOM, PDF, and EHR files to GCP, employing Terraform for infrastructure automation and RabbitMQ for fault-tolerant message queues.

• Designed and optimized data models in PostgreSQL and MSSQL, leveraging indexing, partitioning, and stored procedures to enhance query performance, reduce latency by 35%, and support high-volume transactional healthcare workloads across multiple services.

• Modernized a legacy JBoss monolith by refactoring it into modular Dockerized microservices orchestrated via Kubernetes, enabling zero-downtime deployments and improving release stability by 40% through database sharding and parallel job execution to support high-throughput services.

• Implemented Vault-secured JWT authentication, secure API design, Clarizen/Sugar integration, and validation services, ensuring secure and compliant data exchange across cloud and healthcare applications.

• Developed a Jenkins-based CI/CD pipeline with rollback, Snyk scanning, and unit testing, integrating Vault for secret management to reduce deployment risk and production defects by 35%, enhancing software quality and reliability across clients.

• Researched new libraries and open-source tools to improve system reliability and performance, contributing enhancements to internal projects with a focus on privacy and secure data exchange.

• Designed scalable API patterns and optimized backend services using TypeScript and Rust to support high-throughput data pipelines and structured communication across microservices. IBM Oct 2017 - May 2021

Application Developer Hyderabad, India

• Designed and built a full-scale enterprise issue-tracking and time-management platform using Java, Spring Boot, and MySQL, designing scalable REST APIs to support SLA-based workflows, cost tracking, and multi-role access control.

• Developed a JIRA-like ticketing module with SLA enforcement, audit logging, and custom workflow configurations, ensuring compliance for thousands of service requests across enterprise operations.

• Automated identity and access management processes by writing 19 AWS Lambda functions in Java connected to S3 and API Gateway, designing scalable REST APIs for over 5,000 users and reducing manual provisioning workload by 75%.

• Optimized performance of core modules using MySQL indexing, query tuning, and Redis caching, increasing application respon- siveness by 40% during high-load periods.

• Collaborated in an Agile team environment, contributing to sprint planning, code reviews, and TDD-driven delivery pipelines using Git and Jenkins to maintain consistent quality and continuous integration.

• Contributed to architecture decisions by designing modular REST APIs and reusable backend components, supporting scalable software development across teams and services.

• Implemented testable code and data flow tracking to improve reliability and observability, collaborating with team members across locations to maintain system stability and performance. Blubirch Jan 2017 - Jun 2017

Android Developer Intern Bengaluru, India

• Developed an offline-first Android inventory application using Java and Google Mobile Vision API, enabling barcode scanning, synchronization with a Node.js backend, and improving warehouse inventory efficiency by 90%. PROJECTS
