About Rani Naga

I’m passionate about building secure, scalable systems that solve real business problems—especially in healthcare and financial domains where accuracy, compliance, and performance truly matter. Over the last 12+ years, I’ve worked at the intersection of engineering and business, transforming complex requirements into reliable, high-impact software solutions.I’ve led modernization initiatives that migrated legacy monolithic applications into cloud-native microservices using.NET, Angular, Azure, and AWS. My experience spans claims processing, EDI 837 transactions, FHIR integrations, and HIPAA-compliant platforms, where I’ve helped teams improve performance, reduce downtime, and streamline data workflows. I’ve also optimized SQL Server workloads, built SSIS-based ETL pipelines, and implemented CI/CD automation that reduced release cycles and improved code quality.Beyond development, I enjoy mentoring engineers, refining architecture decisions, and collaborating with stakeholders to ensure solutions align with long-term business goals. Recently, I’ve been integrating AI-driven capabilities, including knowledge assistants and automation workflows, to enhance productivity and operational efficiency.I’m currently open to senior-level.NET, cloud-native, and healthcare-focused engineering opportunities where I can contribute to scalable architecture, secure system design, and high-performing development teams.
