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.

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.
Wiring Azure File Persistent Storage for Notification and Batch Services on AKS Staging
Added PVCs and wired volume mounts for the notification and batch services across two namespaces on AKS staging, replacing stale AWS StorageClass references and correcting two naming and access mode mistakes made in the process.
PeerDB Enterprise on EKS: Helm Repository Move, Temporal Schema Bootstrap, and Catalog Secret Keys
Deployed PeerDB Enterprise on EKS against an RDS catalog backend and resolved three undocumented blockers: the moved Helm repository, missing Temporal schema migrations, and a six-key catalog secret requirement.
