I build cloud platforms, DevSecOps systems, and AI/data infrastructure across enterprise finance, fintech, and NGO environments. In 2026, this portfolio is focused on a public AKS AI Infrastructure Lab: a 45-week, ~80-lab build program with ~84 code-heavy posts documenting what actually works.
AI Infra Lab 2026
~80 disposable AKS labs across 45 weeks (1–2 days each), each isolated by namespace, instrumented, measurable, teardown-friendly, and tied to a publishable result.
2 posts / week cadence
Monday infra concept + Thursday AI concept. Screenshot-led, code-heavy posts with real measurements, one tradeoff, and one production rule per post.

Cleaning Up a Kubernetes Manifest Directory That Got Away From You
The k8s/ directory had stale ingresses, ambiguously named files, missing service manifests, plaintext credentials in a text file, and image tags months out of date. Here is how it was restructured.
terraform.tfstate, a Live VPN Key, and 100MB of Provider Binaries Committed on Day One
Audited a six-month-old Terraform repo and found the state file, a live VPN pre-shared key, and all provider binaries committed in the initial push, then removed them from tracking and migrated state to an Azure Storage backend.
Installing Karpenter 1.8 on EKS 1.34: Four Errors and a Working Cluster
Installed Karpenter 1.8 on EKS 1.34 by working through a Helm registry migration, a version compatibility gap, a feature gate parsing bug, and a missing aws-auth entry — alongside a cost audit that cut $23/month.
Kit Confirmation Emails Not Sending From a Static Astro Site
Traced a silent 200-OK with no confirmation email through a wrong API version, a 12-hour per-address suppression window, and a per-form template scope that doesn't inherit globally.

Field notes, lab write-ups, infrastructure deep-dives, and AI content as they ship. What I built, what broke, what the numbers showed. No fluff.
