What I'm looking for

I am seeking senior engineering or architecture roles where I can lead full-stack/cloud projects, modernize systems, mentor teams, and drive CI/CD and performance improvements.

I am a senior full-stack developer and software architect with 12+ years building web and cloud applications across healthcare, finance, and SaaS. I lead end-to-end projects—architecture, development, UI/UX, testing, and support—while mentoring teams and establishing coding standards.

My technical expertise spans .NET (Core, C#, VB.NET, MVC, Blazor), Angular (2–19+), React, TypeScript, JavaScript, SQL, and cloud platforms including Azure, AWS, and GCP. I have delivered high-performance, scalable solutions (microservices, serverless, Docker/Kubernetes), optimized large ETL pipelines, and modernized legacy systems.

I drive measurable improvements—migration to modern stacks, CI/CD automation, caching strategies, and performance tuning—resulting in faster response times, increased reliability, and robust security for HIPAA-compliant and enterprise applications.
