Hello! I'm Arun J

I'm a passionate Full Stack Developer with 3+ years of experience developing scalable web applications using .NET, Node.js, Angular, and modern databases and I specialize in creating robust healthcare and insurance technology solutions, serving clients like Wellmark Health Insurance.

My expertise spans across multiple technology stacks - from building RESTful APIs with ASP.NET Core and Node.js to creating responsive front-end applications with Angular and TypeScript. I have extensive experience in microservices architecture, cloud deployment (Azure), and healthcare domain applications including claims processing systems using Trizetto Facets.

Throughout my career progression from Programmer Analyst Trainee to Associate, I've successfully delivered full-stack solutions for major clients including Premera and Wellmark using both .NET and Node.js ecosystems. I'm Microsoft Azure Fundamentals (AZ-900) certified and have contributed to insurance claims processing systems serving 500K+ members. My goal is to leverage my technical skills and domain knowledge to contribute to innovative software solutions.
