A technical engineer's blog: real problems, real fixes, real numbers. Backend, databases, infra, incident post-mortems, security, AI-native workflows.
Treat a disk that fails on writes as read-only: stream pg_dump over SSH to the target, pull EOL images from the registry instead of rebuilding them, and anchor rsync excludes with a leading slash. Notes from moving a 14-service Docker app with a 12 GB PostgreSQL database.
PHP, Laravel, GraphQL, domain modeling, server-side architecture. Notes from mature monoliths and greenfields.
PostgreSQL, ClickHouse, MySQL. Migrations, optimization under load, incident post-mortems, escaping rules, common traps in mixed stacks.
Ansible, Terraform, Proxmox, libvirt/KVM, Docker, LXC, edge proxies, network, DNS. Bare metal, no clouds.
Post-mortems with the full diagnosis: hypotheses, ruled-out theories, root cause, real numbers. How systems actually break.
CrowdSec, SSH, TLS, secrets, hardening. Replacing ritual defense with something you can actually verify.
Claude Code, MCP, agent memory, skill conventions, workflows. Building software with an AI partner, as a process.
iOS, SwiftUI, Apollo GraphQL. Live client-server integrations, server-driven UI, debugging the network layer.
