Staff Software Engineer specializing in full-stack, AI/ML, and cloud.
United StatesWhat I'm looking for
I am a proactive, results-driven Staff Software Engineer with over 13 years of experience building scalable full-stack systems for financial, insurance, and healthcare industries across enterprise and startup environments. I specialize in designing microservices, cloud infrastructure on AWS and GCP, AI/ML solutions, and production DevOps workflows to deliver reliable, high-performance products.
I have led cross-functional teams to build AI-driven fraud detection, RAG-based advisory systems, real-time payment and market-data services, and large-scale ETL and streaming pipelines. My technical breadth spans backend (Go, Django, FastAPI), cloud/DevOps (EKS, OpenShift, Terraform, CI/CD), data and ML (Spark, TensorFlow/PyTorch, LangChain), and observability, enabling me to drive end-to-end delivery in remote-first organizations.
