What I'm looking for

I seek senior engineering roles where I can build scalable cloud-native platforms, mentor teams, drive migrations to microservices, and deliver measurable business impact in collaborative, growth-oriented environments.

I am a Senior Software Engineer with 13+ years designing and scaling full-stack applications using Node.js, TypeScript, React/Angular, and AWS/GCP. I build APIs and platforms that handle high-volume traffic and complex business workflows, and I lead migrations from monoliths to microservices.

My work has delivered measurable outcomes: platforms processing 10M+ monthly transactions, paralegal review efficiency improvements of 40%, and support for 50K+ concurrent users. I implement robust CI/CD, test coverage, and observability practices to reduce defects and accelerate releases.

I mentor engineers, author technical documentation and run books, and collaborate with product and DevOps to drive reliability and adoption. I seek to apply pragmatic engineering and cloud-native design to solve high-impact problems at scale.
