What I'm looking for

I seek roles building production-grade AI or platform systems where I can drive agentic AI, observability, secure auditability, and scalable cloud-native deployments in cross-functional teams.

I am a Senior Full Stack Engineer with 10+ years building AI-powered platforms, web systems, and developer tools across startups and enterprise environments. I design and deliver end-to-end solutions from requirements and architecture to deployment and monitoring.

My recent work centers on agentic AI, RAG, and secure auditability, I built an AI agent orchestration platform, real-time incident monitoring, and blockchain-based audit logging while integrating AWS Bedrock, SageMaker, and LangGraph for production-grade reliability.

I bring broad frontend and backend expertise (React, Angular, Vue, Node.js, FastAPI, Django), strong cloud and CI/CD practice (AWS, Azure, Docker, Kubernetes, Terraform), and a proven record of improving user engagement, reducing manual workloads, and enabling compliant, auditable AI workflows.
