I take apart systems other people built and say what to do next.

Approach & solution. Wrote the missing half: a Node and Express server with SQLite, implementing the same client-API the RustDesk client calls, plus a browser panel with registration, devices and address book. The API contract is undocumented, so it was recovered from the client sources. Three findings paid for the effort: the address book is more reliable served in legacy mode, the api-server address will not fit into the filename config format because a colon is illegal in Windows filenames, and the address book's hash field is a ready-to-use connect credential rather than a fingerprint, so it gets encrypted at rest.

Approach & solution. Forked and carried forward to FreeBSD 15: six repositories covering the operating system, middleware, build system and web interface, a build that works again, and installable images. The CORE build system had to be understood end to end first, since it is FreeBSD-make wrapped around a Python DSL with its own repository manifest.

Approach & solution. Moved to PHP 8.3 and PostgreSQL 16 under Docker Compose. The deciding choice was to leave the business logic alone: the legacy code runs as it is, odbc_* calls are shimmed onto pg_*, functions dropped from PHP over twenty years come back as polyfills. Correctness is verified by replaying the nightly billing run on a copy and reconciling against the daily dumps of the live DB2 database, day after day across months.

Approach & solution. Hidden-primary PowerDNS with authoritative NSD edge nodes in several countries, two NS pools split by region, wildcard certificates issued automatically over DNS-01, scheduled zone sync. Every zone was reconciled against the old provider before the delegation was cut over.

Approach & solution. One technical core carries markup, form, captcha and backend; per-domain content, theme and keywords live in data. A single Ansible run loops over every site, and one shared form backend tags each submission with its source. Adding a site is a row in the inventory plus its content.
