What I'm looking for

I seek senior full-stack or backend roles leading cloud-native, microservices projects where I can mentor engineers, work in collaborative cross-functional teams, and deliver scalable, secure healthcare or enterprise applications with strong CI/CD practices.

I am a Senior Software Engineer with 5+ years of experience building scalable, high-performance applications. I focus on practical, user-centered solutions and maintainable code while consistently delivering features within collaborative, cross-functional teams.

I have led major migrations and platform modernizations—rewriting legacy Java systems to .NET Core 8 with React frontends, implementing CQRS and microservices with EF Core and MySQL, and integrating major EMRs (Redox, Athena, EPIC, eCW). I configure Azure DevOps CI/CD, Azure AD B2C authentication, and implement robust testing practices to reduce defects and improve reliability.

I mentor junior developers, run code reviews and knowledge-sharing sessions, and thrive in environments that value clean architecture and continuous improvement. I graduated with honors (cum laude) in Computer Science and seek opportunities to drive technical excellence in cloud-native and enterprise healthcare projects.
