Senior DevOps / Platform / SRE Engineer · MLOps · AIOps · GenAI/LLMOps

I build and operate cloud-native infrastructure that teams can trust — and lately, the platforms that put machine learning and LLMs into production. Thirteen years across big tech, investment banking, 5G telco and AI products: from moving a global telco’s core billing off the mainframe, to owning ML lifecycles end to end, to running agentic AIOps in production.

What I do

Four areas where I go deep. The first two are where most DevOps engineers live; the last two are where I spend my time now.

Platform Engineering

Building the paved road so other teams ship without filing tickets.

  • Reproducible, auditable environments with Terraform, Ansible and cloud-init
  • GitOps delivery with Flux and Argo CD reconciling apps on Kubernetes
  • CI/CD across GitLab CI, GitHub Actions and Jenkins
  • Self-service tooling that removes humans from the critical path
  • Terraform
  • Kubernetes
  • Flux
  • Argo CD
  • GitLab CI
  • Helm

Reliability & Observability

Instrumenting systems before the incident, not during it.

  • Prometheus, Grafana, Alertmanager and OpenTelemetry distributed tracing
  • High availability and disaster recovery on life-critical systems
  • Incident response and postmortems that change the system, not the person
  • Cost optimization as a reliability concern, not an afterthought
  • Prometheus
  • Grafana
  • OpenTelemetry
  • AWS X-Ray
  • Sentry
  • ELK

MLOps

Owning the path from a model that works to a model that serves.

  • End-to-end ML lifecycle: data processing, training, tuning, deployment
  • AWS SageMaker pipelines and AWS IoT Greengrass for edge inference
  • Computer vision in production — PyTorch, YOLOv8, OpenCV
  • Treating models as deployable artifacts with the same rigor as services
  • SageMaker
  • PyTorch
  • YOLOv8
  • OpenCV
  • IoT Greengrass

AIOps & GenAI

Agentic workflows wired into CI/CD and monitoring — running in production today.

  • Agentic AIOps on the Anthropic SDK that investigates alerts automatically
  • Proactive issue detection ahead of the pager
  • Leading LLM adoption across the SDLC — skills, subagents and hooks
  • RAG-oriented design and LLMOps practices for embedding models in products
  • Anthropic Claude SDK
  • LLMOps
  • RAG
  • Python
  • Agentic CI/CD

Impact in production

Three projects where the number is the story. All of them ran in production, under real constraints.

Vodafone

The UK’s 999 emergency service, re-engineered for 5G

  • ~1,000–2,000 ms <100 ms

    Emergency-call re-routing time

  • <10 s

    AML (Advanced Mobile Location) response

A life-critical, heavily regulated system where a slow re-route is a person waiting for an ambulance. I designed the end-to-end Kubernetes architecture — non-production and production — and containerized the legacy stack, writing every manifest and a Helm chart per microservice.

Built the CI/CD pipelines and the whole delivery toolchain from scratch — Jenkins, Nexus, GitLab and Argo CD — plus observability and distributed tracing with Prometheus, Grafana, Alertmanager and OpenTelemetry.

  • Kubernetes
  • Helm
  • Argo CD
  • OpenTelemetry
  • 5G
  • Regulated
Vodafone

Self-service VM provisioning for the whole engineering org

  • ~2 weeks instant

    Time to provision, after approval

Provisioning a virtual machine meant a ticket and roughly two weeks of waiting. I designed and built the platform that removed the queue entirely.

A Node.js/Angular portal in front of Terraform, Jenkins, cloud-init and Python automation — approval stayed a human decision, everything after it stopped being one.

  • Terraform
  • Jenkins
  • cloud-init
  • Node.js
  • Self-service
IBM

A global telco’s billing core, off the mainframe

  • Mainframe / COBOL Linux / Java

    Core billing platform

  • 600+

    Red Hat Linux servers operated on vSphere

The largest billing application of a North American global telco, running on Mainframe and COBOL. I worked the migration to Linux and Java while operating the estate it ran on.

Production and development estates on vSphere alongside Mainframe MVS, with Jenkins, Docker, Terraform and Chef for delivery and configuration.

  • Java
  • COBOL
  • vSphere
  • Terraform
  • Chef

How I work

  • automate_over_toil true

    If it hurt twice, it becomes a pipeline. Manual work is a bug report about the platform.

  • infrastructure_as_code always

    Nothing reaches production unless it is versioned, reviewable and reproducible.

  • observability_first true

    Instrument before the incident. Debugging blind at 3 a.m. is a choice made months earlier.

  • own_code_and_infra true

    Horizontal teams work. Whoever writes the service should be able to operate it.

  • blameless_postmortems true

    The failure is in the system, not the person. Otherwise people stop reporting the near-misses.

  • ai_as_leverage true

    LLMs take repetitive work off the path. They do not replace judgement, and I do not pretend otherwise.

Experience

System Engineer Apple

Jun 2025 – Present Cupertino, CA · Remote

Building and operating internal cloud-native platforms at the intersection of DevOps, Cloud and applied Generative AI, on a horizontal team where every engineer owns both code and infrastructure.

  • Design and run CI/CD across GitLab CI and GitHub Actions with GitOps-based continuous delivery (Flux) reconciling applications on Kubernetes (EKS).
  • Implement monitoring and observability — AWS Managed Prometheus & Grafana, X-Ray, Sentry — to keep business-critical systems reliable and highly available.
  • Lead LLM / GenAI adoption across the SDLC, creating and sharing Claude skills, subagents and hooks; act as the team’s LLM/GenAI specialist for embedding LLMs into production.
  • Pioneer AIOps with agentic workflows on the Anthropic SDK integrated into CI/CD and monitoring, automating alert investigation and proactive issue detection.

Migrated the UK’s 999 emergency-call service to 5G — re-engineering and containerizing a life-critical, highly regulated system on Kubernetes.

  • Designed the end-to-end Kubernetes architecture (non-prod + production) for high availability and fault tolerance; containerized legacy apps with all manifests and a Helm chart per microservice.
