Alex Albu

> platform engineer at capital on tap

I design and run internal platforms on Kubernetes that let product teams ship without thinking about infrastructure. That means Go operators and custom resources, GitOps with Flux, event-driven autoscaling, and the Terraform, identity and Cloudflare edge around them. Five years across fintech, e-commerce and AWS consultancy. Based in London.

capital-on-tap Platform Engineer

London

# fintech · business credit cards for small businesses in the UK and US · Azure, AKS, Flux

Built a governed AI access layer that let production workloads and apps built by non-engineering teams use Azure AI Foundry and Anthropic models safely, with all traffic routed through a central agent gateway for authentication, policy enforcement and usage tracking.
Lead the design and delivery of several CRDs in the platform's Go operator (Kubebuilder, CEL validation), improving the developer experience around self-service infrastructure.
Introduced event-driven autoscaling (KEDA) into the k8s platform's CRDs, giving product teams queue-driven and scale-to-zero scaling out of the box and cutting compute costs by an estimated 30 to 40%.

Owned the platform for a high-traffic e-commerce business: infrastructure as code, CI/CD and deployments, observability, DNS and the Cloudflare edge, as the platform partner to the backend and data teams.
Introduced load testing for peak trading which greatly improved overall scaling performance. Wrote it up for the engineering blog.
Led the move of image resizing from a self-hosted Lambda to Cloudflare Image Transformations across web, iOS and Android, with a Cloudflare Worker redirecting legacy URLs with 0 downtime.
Built bw-cli, an open source k9s-style terminal UI for ECS.

homelab/

A GitOps-managed k3s platform on mixed hardware that runs a public e-commerce shop alongside home services. Everything in the cluster is declared in Git and reconciled by Flux.

Zero-trust ingress. Cloudflare Tunnel into Istio with the Gateway API, Cloudflare Access with Google sign-in in front of every admin page, and Grafana signing users in from the Access token.
Recoverable data. Postgres on CloudNativePG with continuous WAL archiving and nightly base backups to Cloudflare R2: 30 days of point-in-time recovery, with backup freshness on a Grafana dashboard.
Supply chain. CI builds multi-arch images and an OCI artifact of each app's manifests; Flux deploys them pinned by digest. Secrets live in Git encrypted with SOPS and age.
Observability. Prometheus and Grafana with cluster, application and business dashboards, generated from code.
Blast radius. Stateful workloads are pinned to the SSD node, and the cluster's DNS stays off the home ad blocker, so a blocklist or a Pi-hole outage can't reach the shop.
Home services. Home Assistant using the Pi's Bluetooth, Jellyfin with Intel Quick Sync transcoding, a download stack behind a VPN, and Pi-hole for the house.

An online shop for a small jewellery business: a Go API, a storefront and an admin app, with Postgres, Valkey, Stripe payments and Google sign-in. Every push publishes a multi-arch image and an OCI artifact of the manifests, and Flux deploys them to the homelab pinned by digest.

Load Testing at Bloom & Wild: Preparing for Peak Success

How we swapped educated guesses about ECS capacity for k6 load tests built from past peak traffic, and what they showed about our autoscaling ahead of Valentine's Day, Mother's Day and Christmas.
