Accomplished Sr. .NET Full Stack Developer with over 10+ years of experience in designing, developing, and deploying enterprise-grade applications across healthcare, finance, retail, and telecom domains. Adept at building scalable back-end solutions using .NET Core/.NET 8, C#, and microservices while delivering responsive and dynamic front-end applications with React.js, TypeScript, and Angular. Proficient in AWS & Azure cloud-native solutions, CI/CD automation, containerization (Docker/Kubernetes), and DevOps practices to enhance performance, scalability, and security. Skilled in SQL/NoSQL databases, API integrations, identity management, and event-driven architectures, with proven expertise in HIPAA, SOX, and financial compliance environments. Strong background in Agile/Scrum methodologies, stakeholder collaboration, and modernizing legacy systems into cloud-first, AI/ML-enabled architectures. Designed and deployed enterprise-grade .NET Core/.NET 8 APIs for healthcare and financial systems, ensuring compliance with HIPAA, security standards, and industry best practices. Developed responsive front-end applications using React.js, TypeScript, Redux Toolkit, React Query, and Angular, improving customer engagement and provider/patient experiences. Built microservices and event-driven architectures leveraging AWS SNS/SQS, Kafka, and Azure Service Bus, ensuring reliability and high scalability across enterprise systems. Experience working in enterprise environments with both .NET and Java-integrated systems. Optimized SQL Server and PostgreSQL databases, improving high-volume transaction processing and data analytics performance through indexing and stored procedures. Adopted NoSQL databases (DynamoDB, MongoDB) to support real-time eligibility, enrollment, and financial transaction data with low-latency retrieval. I understand SOAP-based services and XML handling, and I am comfortable working with API integrations, so I can quickly adapt to SOAP if required. Integrated OAuth2, OpenID Connect, AWS Cognito, and Identity Server, implementing secure authentication/authorization for healthcare and financial systems. Migrated legacy ASP.NET MVC and .NET Framework apps to .NET 7/8 with React, modernizing performance, maintainability, and scalability. Designed and developed reusable components and frameworks for scalable applications. Strong experience in T-SQL for database development and optimization. Leveraged AWS cloud-native services (Lambda, ECS, API Gateway, S3, CloudFormation, and CodePipeline) for cost optimization, high availability, and automated deployments. Automated CI/CD pipelines using GitHub Actions, Azure DevOps, AWS CodeBuild, and Terraform, reducing release cycle times and deployment errors. Implemented containerization and orchestration with Docker, Kubernetes (EKS), and ECS, streamlining deployments and improving environment consistency. Enhanced observability and monitoring with AWS CloudWatch, ELK Stack, X-Ray, and Application Insights, enabling predictive monitoring and reduced downtime. Developed RESTful and GraphQL APIs for third-party integrations with healthcare vendors, payment gateways, and analytics providers. Collaborated with cross-functional teams including UI/UX designers, product owners, and data engineers to translate requirements into secure, scalable applications. Improved front-end performance using custom hooks, caching strategies, React Query, and Tailwind CSS, ensuring fast and seamless workflows. Led Agile ceremonies such as sprint planning, backlog refinement, and reviews, aligning development deliverables with evolving business priorities. Built automated test frameworks (xUnit, NUnit, Jest, Cypress, React Testing Library) ensuring high-quality applications across front-end and back-end. Integrated AI/ML and MLOps practices for predictive healthcare cost modeling, patient outcomes analysis, and automated claim documentation workflows. Developed Python-based utilities for data validation, ETL processing, and automation, supporting analytics and cross-team operations. Ensured compliance and governance in healthcare and financial domains, implementing secure APIs, audit trails, and industry-standard encryption. Mentored junior developers and conducted code reviews, fostering knowledge sharing and maintaining clean, scalable, and maintainable architectures.
