Hi there πŸ‘‹

I'm a Principal SRE and Platform Engineer at Oracle Health, building cloud-native infrastructure and operational tooling in Go for FedRAMP-regulated healthcare workloads.

Go Kubernetes OCI Terraform OpenTelemetry Prometheus Istio

What I build

  • Platform tooling β€” Go CLIs, automation frameworks, and internal developer platforms that eliminate toil and give teams self-service capabilities
  • Observability β€” OpenTelemetry pipelines, Prometheus, distributed tracing, and SLI/SLO instrumentation across multi-cluster Kubernetes (OKE)
  • Infrastructure automation β€” Terraform, OCI Functions, External Secrets + OCI Vault, event-driven provisioning, and zero-touch deployment
  • Service mesh & security β€” Istio traffic management, mTLS, and hardened Kubernetes clusters (CKS)
  • Reliability at scale β€” Incident response, runbooks, and large-scale database migrations (MySQL β†’ HeatWave, Redis β†’ OCI Cache/Valkey) across 100+ services

Current focus

Standardizing observability and platform patterns across a fleet of 100+ services on OCI (FedRAMP OC2) β€” OpenTelemetry, Prometheus, OKE, Go, and whatever removes the next piece of manual toil.

Also exploring MLOps and applied GenAI β€” RAG architecture, grounded-answer contracts, model evaluation, and treating LLM accuracy as a testable, regression-gated concern rather than a vibe.

πŸ“Œ Featured

ocloud β€” my open-source Go CLI for OCI operations, adopted as the org-standard operational tool and used daily across my team.

OpenLex β€” a POC retrieval-augmented legal research assistant (NY landlord-tenant law) I built to learn MLOps by running an LLM system the way I'd run any production service. Hybrid retrieval (pgvector + Postgres FTS), grounded citations that answer only from retrieved statute, and β€” the part I care about most β€” a CI-gated legal-accuracy evaluation harness: 21 golden questions with known-correct citations fired against a live stack, run on cheap Haiku in CI and the production Sonnet model on demand, with a live evaluation report publishing per-question pass/fail, Haiku-vs-Sonnet divergence, and statute-freshness drift. Applying SRE regression-gating and cost-awareness to GenAI, not just wiring up a demo.
