What I'm looking for

I seek a role building scalable cloud-native applications where I can lead architecture, mentor teams, and improve performance through DevOps and microservices.

I am a Senior Full-Stack Developer with 8+ years building scalable web applications, SaaS platforms, and microservices across healthcare, education, and finance. I specialize in .NET (C#), cloud platforms (AWS, Azure, GCP), and modern frontend frameworks like Angular and React, delivering performance improvements, migrations to microservices, and CI/CD automation.

I lead cross-functional teams, mentor junior developers, and drive architecture and refactoring efforts that reduced load times and downtime while improving reliability and user satisfaction. I focus on pragmatic engineering, DevOps best practices, and measurable outcomes—such as reduced deployment times, improved system performance, and high client satisfaction.
