What I'm looking for

I’m looking for a team where I can combine AI agents with full-stack delivery—building automation, event-driven cloud systems, and measurable impact—while owning production reliability through CI/CD, monitoring, and guardrails.

I’m a Senior AI & Full Stack Engineer focused on building automation-centric intelligent systems and scalable web applications. I’ve led the development of autonomous LLM agents that cut manual review effort by 20% and built AI automation pipelines that streamlined high-volume processing.

I design cloud-native, event-driven architectures across AWS, GCP, and Azure, integrating production-grade CI/CD, monitoring, and guardrails. In Python, I’ve built feedback-driven learning pipelines with AssemblyAI and LangGraph to turn user interactions into structured datasets, shortening retraining cycles and improving domain adaptation.

On the full-stack side, I deliver reliable web and API platforms using Node.js/TypeScript, FastAPI, Django, React/Next.js, GraphQL, and Tailwind-based dashboards. From orchestration with AWS CDK and Dockerized services to CI/CD automation with GitHub Actions, I translate business signals into measurable metrics and dependable systems that teams can trust.
