AI Engineer × Platform Engineer — I build LLM products and the infrastructure that runs them

LLMs & RAG · Python · FastAPI · Kubernetes · Terraform · AWS · Azure · DevSecOps

LinkedIn Email Location

I build AI-driven products end to end — RAG pipelines, LLM-powered developer tooling, ML inference services — on top of 8+ years running cloud infrastructure at scale. That pairing is the whole point: prototyping with a model is the easy part, and everything after it (serving, securing, scaling, and paying for it) is where projects actually live or die.

🔭 Currently building — LLM-powered developer tooling: AI security triage that separates real risk from scanner noise (VulnSift) and a secrets platform that stops credentials before they reach a commit (SecretSentinel).

🔧 Focus areas

  • LLM applications — RAG pipelines end to end (chunking, embeddings, vector search, citation-grounded answers), Claude & OpenAI API integration, prompt/cost controls, streaming UX
  • ML services — reproducible training pipelines, real-time and batch inference APIs, versioned model artifacts with metrics, health probes and deployment readiness
  • Platform & IaC — EKS / AKS, reusable Terraform module libraries, GitOps (ArgoCD), self-hosted & air-gapped LLM serving, self-service infrastructure
  • DevSecOps & SRE — SAST / SCA / IaC scanning, SBOM and supply-chain security (SLSA), SLOs, observability (Prometheus / Grafana / OpenTelemetry), FinOps
