Practical notes from client work: cloud infrastructure, PHP runtime security, containers and the adoption of AI tools in engineering teams.
After 31 December 2026 the PHP project publishes no more security fixes for PHP 8.2. How to check what you run, what your stack supports, and how to move to a supported version without rewriting the application.
Unused resources, oversized servers, NAT gateways, data transfer, logs kept indefinitely: the most common reasons an AWS bill grows, the AWS tools that show where the money goes, and where to start.
From servers set up by hand to applications that are built, tested and deployed the same way every time: what containers and DevOps change, the order that works, the mistakes that cost the most, and when Kubernetes is worth it.
Well-known examples from Replit, Amazon, Samsung, Google and Airbnb, and what they teach IT teams about access, the supply chain, company data, review, automatic checks and training when introducing AI coding assistants such as Claude Code.
