I deploy 𝗗𝗼𝗰𝗸𝗲𝗿 applications and build 𝗣𝗿𝗼𝘅𝗺𝗼𝘅 and self-hosted 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 environments. I handle the 𝗟𝗶𝗻𝘂𝘅, networking, storage, backups, and monitoring behind them, with clear documentation for your team. My specialty is infrastructure you own. I work across the hypervisor, Linux host, network, and container platform to get deployments working and resolve problems between those layers. CLIENT WORK & PORTFOLIO Client work includes 𝗥𝗼𝗰𝗸𝘆 𝗟𝗶𝗻𝘂𝘅 VMs on 𝗣𝗿𝗼𝘅𝗺𝗼𝘅, 𝗗𝗼𝗰𝗸𝗲𝗿 and 𝗣𝗼𝗿𝘁𝗮𝗶𝗻𝗲𝗿 setup, and 𝗣𝗿𝗼𝘅𝗺𝗼𝘅 𝗕𝗮𝗰𝗸𝘂𝗽 𝗦𝗲𝗿𝘃𝗲𝗿 configuration with documented restore testing. I also build 𝗭𝗮𝗯𝗯𝗶𝘅 𝗱𝗮𝘀𝗵𝗯𝗼𝗮𝗿𝗱𝘀 that help clients monitor infrastructure health and resource usage. My portfolio covers 𝗗𝗼𝗰𝗸𝗲𝗿 infrastructure, 𝗣𝗿𝗼𝘅𝗺𝗼𝘅 with 𝗖𝗲𝗽𝗵 and 𝗭𝗙𝗦, and 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 with 𝗥𝗼𝗼𝗸 𝗖𝗲𝗽𝗵.

Recovery and handover are part of the work. Send me your current setup, the outcome you need, and any downtime constraints. I’ll explain the approach and what the work involves.
