· Documented existing APIs using Go-Swagger for seamless integration and clarity, worked on API security, handling JWT-based authentication, certificate management. · Developed and maintained backend services using Golang and Java, ensuring clean, testable code and efficient performance in a cloud-native environment. · Developed internal monitoring dashboards and health probes using Prometheus and Grafana for Kubernetes workloads, enabling faster incident response during on-call rotations. · Used Go-Chi’s middleware for tasks like authentication and request validation, keeping the code modular and clean. · Architected and delivered Go-based microservices on AWS Lambda and EKS, using Terraform for infrastructure as code and Docker for containerization. · Developed internal APIs using gRPC to reduce latency and payload size compared to RESTful alternatives. · Integrated gRPC-based microservices with API Gateway using gRPC-Web and Envoy proxy to expose services securely to front-end applications. · Experienced in React DOM, Props, Lifecycle methods, States, and Events, building reusable components and single-page apps that reduced code duplication by 20%. · Focused on designing RESTful APIs & optimizing inter-service communication while ensuring concurrency with goroutines & channels. · · Used channels as signaling mechanisms to implement graceful shutdown logic for long-running goroutines, ensuring proper cleanup during service termination. · Deployed Java Spring Boot microservices on AWS Fargate using ECS, removing the need to manage EC2 servers. · Integrated AWS Secrets Manager to securely store and retrieve application credentials and API keys, eliminating hard-coded secrets and supporting automatic rotation. · Used Protobuf reflection and dynamic message handling for logging, validation, and schema testing tools in a multi-service ecosystem. ·

At Little Caesars, I developed a responsive ordering and inventory management platform. My focus was to optimize performance and scalability through microservices built with Golang and front-end React components. Key Contributions: Designed scalable backend modules using Java 11, utilizing enhancements such as var-type inference, HTTP client APIs, and improved garbage collection tuning. Built microservices using Gin and GoKit, implemented gRPC-Gateway for hybrid REST/gRPC exposure. Designed infrastructure using AWS services (EKS, S3, CloudFront, DynamoDB) and monitored deployments with Prometheus and Grafana. Created dynamic ReactJS interfaces with Redux, enabling real-time inventory tracking and order customization. · Implemented unit and integration tests in Python using unittest and pytest, improving code reliability and reducing production bugs. Automated deployments with Docker, Helm Charts, and Jenkins CI/CD pipelines. Integrated Kafka for asynchronous event publishing/consuming in order lifecycle and inventory sync.

At Cohesive Digital, I contributed to healthcare technology initiatives, including the Utah State of Health portal and other Medicaid/Medicare-driven systems. My work centered on developing secure, scalable applications for managing patient records, appointments, and prescriptions, with strict adherence to HIPAA compliance. Key Contributions: Developed and maintained full-stack features for Medicaid and Medicare systems, enabling efficient claims processing, eligibility checks, and secure patient data retrieval Built secure RESTful APIs using Spring MVC, Spring Security, and Hibernate, ensuring robust data protection with JWT and TLS encryption. · Built RESTful APIs with Python (Flask/FastAPI) to expose backend services for internal and external applications · Automated repetitive operational tasks using Python Utilized MongoDB and PostgreSQL for handling large volumes of patient and insurance records. Ensured infrastructure and data handling adhered to HIPAA guidelines and CMS (Centers for Medicare & Medicaid Services) specifications. Containerized applications using Docker and automated CI/CD processes with Jenkins and Nexus. Collaborated with QA teams and business analysts to define use cases related to insurance eligibility, provider lookup, and benefits tracking for Medicaid and Medicare users.
