How I used three IaC tools — Pulumi, Terraform, and OpenTofu — to deploy an AI translation endpoint on AWS SageMaker without touching the console once. Architecture, failure modes, and what I actually learned.

A practical breakdown of containerizing and deploying applications on AWS with proper secrets management — architecture decisions, IAM patterns, and what actually works in production.

A breakdown of building a CLI tool to audit AWS Security Groups at scale — architecture decisions, failure modes, and what production-ready security tooling actually looks like.

A practical breakdown of running your own Git server on AWS EC2 — Nginx reverse proxy, MySQL, SSL, automated backups, and every error worth documenting.

A practical breakdown of deploying a mathematical classification API on AWS Lambda with API Gateway — input validation, CORS preflight handling, edge cases, and what serverless actually looks like in production.

A practical reference for configuring NGINX on Ubuntu 22.04 on AWS EC2 — security groups, file permission models, the full 403 debugging chain, and what production-ready actually looks like for a web server setup.
