CHAPTER 01 · THE PERSON

I build the platforms other people's code runs on, quietly, so they never become the story.

AWS

Kubernetes

Docker

Terraform

Prometheus

Grafana

n8n

Supabase

why devops?

My journey, philosophy, and what drives me

My Journey

Frictionless Deployments

I fell in love with DevOps when I realized deployments were the invisible bottleneck. Teams shipped code, but getting it to production safely and reliably was where the real problem lived. I became obsessed with removing that friction—building systems where infrastructure gets out of the way so engineers focus on shipping.

My Philosophy

Boring Infrastructure

I believe infrastructure should be boring. Not in a boring-as-in-uninteresting way, but in a boring-as-in-it-just-works way. No surprises at 3am. No manual firefighting. Systems designed with reliability and automation at the core.

Velocity & Flow

Faster Than Light

Sub-minute feedback loops, automated canary deployments, and reproducible artifacts. Scaling happens invisibly, and telemetry tells the story of what's happening before it becomes a problem.

What I Value

Reliability at Scale

I'm passionate about infrastructure that's reproducible, observable, and cost-conscious. I love solving problems that have scale (500+ users, millions of requests) where resilience under pressure matters.

Platform Culture

Operational Excellence

I value teams that care about operational excellence and aren't afraid to question "the way we've always done it." Building transparent, automated pipelines where engineers ship with confidence and shared ownership.

CHAPTER 02 · THE ROAD

None of it came from a course. It was learned on the job, with real traffic, real pagers and real deadlines.

cloud architecture & systems

How the multi-tenant merchant platform handles a request, and how a change gets to production safely.

Read the case study

Step 1 of 6

Follow one merchant request from the edge to the metrics that watch it.

Merchant Clients

Ingress Traffic · TCP:22 / HTTPS:443

Tenant Isolation

The problem

500+ independent merchants requiring isolated credential boundaries, private directory trees, and zero cross-tenant visibility.

What I built

Per-tenant chroot directory containment with automated credential rotation managed through Terraform and AWS Secrets Manager.

500+ Tenants
SFTP Clients
REST Consumers

transfer-family.tf

resource "aws_transfer_user" "merchant" {
  server_id      = aws_transfer_server.sftp.id
  user_name      = each.key
  role           = aws_iam_role.sftp_tenant.arn
  home_directory = "/bucket/tenants/${each.key}"
}

CHAPTER 04 · THE CRAFT

Behind every project is a toolbox, and a few defaults I keep until the problem says otherwise.

skills & expertise

Technologies and tools I work with, by area.

skill dependencies

How the skills fit together, at a glance. Select anything to explore it.

Five outcomes, one loop

Infrastructure, security, cost, observability and automation all run through one DevOps practice. Select an area to explore it.

Shipped as case studies

The map ends in real systems with numbers to show for them. Select the front sheet to read one.

The toolchain

Terraform, Kubernetes, GitHub Actions and Prometheus do the heavy lifting, each wired into production work. Terraform: Infrastructure as Code Migration, Multi-Tenant Merchant Platform.

Most connected skills

Ranked by how many other skills each one links to on the map. AWS sits at the centre of most of them.

engineering philosophy

Defaults I reach for until the problem demands otherwise.

Stateless by Default

Push state to databases, caches, object stores. Compute is cheap; state is a liability.

Design for Failure

Retries, circuit breakers, graceful degradation. If it can't survive a node down at 3 AM, it's not prod-ready.

Observability > Monitoring

Monitoring says it's broken. Observability says why. Structured logs, traces, SLI-driven alerts.

IaC or It Didn't Happen

Not in version control? Doesn't exist. Terraform for infra, Actions for pipelines, PRs for changes.

CHAPTER 05 · THE PROOF

Don't take my word for it. Here is what the people I worked with say, and what is on record.
