What I'm looking for

I seek senior engineering roles building secure, cloud-native and AI-integrated systems with strong CI/CD, mentoring opportunities, and a focus on healthcare or finance compliance.

I am a Senior Full Stack Engineer with extensive experience designing and scaling cloud-native microservices and enterprise-grade systems across healthcare, finance, and AI-driven platforms. I build backend architectures using Node.js (Express/NestJS) and Python (Django/FastAPI), integrate LLMs and ML pipelines for real-time workflows, and deploy compliant solutions on Azure and AWS.

I have led technical initiatives including RAG pipelines, fine-tuning domain LLMs, and automating CI/CD with Azure DevOps, GitHub Actions, and Terraform. I mentor engineers, drive adoption of microservice best practices, and deliver secure, HIPAA-compliant solutions that improve scalability, performance, and user experience.
