Reliable applications at a sensible cost: AWS, containers, PHP and Claude Code
PHP securityCritical PHP vulnerabilities such as PHP2Shell (CVE-2026-109618, CVE-2026-109619) are fixed in official releases only for supported PHP versions.What to check and how I can help
I build and run AWS infrastructure.
I have worked in IT since 2012, and I design and run infrastructure on AWS. I lead the DevOps team and, as interim lead, the AppOps team (9 people) at a qualified trust service provider, where I built the AWS platform within its eIDAS requirements. At Talk-A-Bot, I introduced AWS and moved the customer projects from DigitalOcean, Azure and Google Cloud onto one AWS setup: cloud costs fell by 77%, with 100% uptime during the migration. I help companies run their applications reliably and at a sensible cost: lower AWS costs, containers and automated releases, supported PHP versions, and Claude Code for IT teams. I work directly with your team and document what I build. After the handover, you choose whether your team runs it or I do. I am based in Spain and work remotely with teams across Europe and beyond. Core expertise: Amazon EKS • Terraform/IaC • CI/CD & GitOps • Infrastructure automation • Docker & Helm
Services
AWS cost reduction & migration
A lower AWS bill and a simpler cloud setup.
I find out where the money goes, draw up a plan to reduce costs and move to AWS, carry it out and hand over a documented setup.
Containerisation & DevOps
Containers and automated releases, without a rewrite.
I move existing applications into containers without rewriting them, automate building, testing and deployment, and keep the infrastructure in code (Terraform). Kubernetes (EKS) only where the workload justifies it.
AI adoption
AI assistants your IT teams use safely and well.
I help IT teams adopt Claude Code: a shared setup and clear rules for access, data and review, for development, operations and DevOps.
Supported PHP versions
Without rewriting your application.
The PHP project releases security updates only for supported versions. I assess where your PHP runs, move the application into containers on a supported version and, if you wish, host and operate it. Code changes stay with your developers or agency.
