Projects

Selected public repositories. Additional work at github.com/mamahoos

  • airbar-financegithub.com/mamahoos/airbar-finance

    Go finance service for ledger, escrow, wallet, and payment-provider callbacks, with idempotency and a real promotion path

  • dot-filesgithub.com/mamahoos/dot-files

    Reproducible Linux environment: the repo mirrors the filesystem, install converges with symlinks, and CI guards the installer

  • Composable Docker infrastructuregithub.com/mamahoos/infra-traefik

    Independent Traefik and PostgreSQL stacks that applications join, so TLS and database lifecycle stay out of every service repo

  • pacman-vpngithub.com/mamahoos/pacman-vpn

    Containerized edge stack that joins existing Traefik and Postgres networks instead of bundling another proxy or database

  • pgsyncgithub.com/mamahoos/pgsync

    One-shot pg_dump | psql sync with rsync-shaped flags, a GHCR Docker image, and ShellCheck/Bats CI through integration tests
