DevOps / Platform Engineer

Mohammad Hosein Kouhkan

I look for the cause, not the symptom, and I design for the next scale, not the current fire. I am not looking for an answer; I am looking for a model that can produce the next ones.

Selected work

• 01Composable Docker infrastructurePlatform engineeringIndependent edge and database stacks that applications join, so TLS and Postgres lifecycle stay out of every service repo.
• 02pacman-vpnEdge infrastructureContainerized edge stack that joins existing Traefik and Postgres networks instead of bundling another proxy or database.
• 03dot-filesLinux engineeringA reproducible Linux environment: the repo mirrors the filesystem, install converges with symlinks, and CI guards the installer and its own maintenance.
• 04pgsyncAutomationA deliberately small wrapper around pg_dump piped to psql — rsync-shaped flags, safer defaults, a GHCR Docker image, and CI from ShellCheck through Bats integration tests.
• 05airbar-financeSoftware architectureA dedicated Go finance service — ledger, escrow, wallet, and PSP callbacks — with dependency direction, idempotency, and a real promotion path.
• 06aiogram-inputConcurrencyWait for the next Telegram message inside a handler without a full FSM — and without stealing unrelated updates.
