A self-contained Go program that parses Nginx access logs and exposes custom Prometheus metrics (request count, latency histogram, status codes). It uses a custom collector and can be extracted to monitor any Nginx instance. Demonstrates non-trivial log parsing and metrics exposition.

A Python script that automates ArgoCD image updater management via the GitHub API. It can pause/resume updates and push changes to a private repository. Reusable for any GitOps workflow that needs to control ArgoCD image updates programmatically.

A reusable Terraform module for creating an AWS VPC with public/private subnets, NAT gateways, and routing tables. It follows Terraform module best practices with input variables and outputs. Can be extracted and used in any Terraform project requiring a standard VPC setup.

An Inspec test file that validates a Packer-built image. It checks that the application binary exists, the service is enabled, and the health endpoint responds. Demonstrates infrastructure testing as part of a Packer build pipeline, reusable for any Packer project.

A Go program that benchmarks serialization/deserialization performance for JSON, Protobuf, and Cap'n Proto using high-resolution timing (TSC). It outputs latency histograms and can be adapted to compare any serialization formats. Demonstrates careful benchmarking methodology.
