The case files
AI-automation case studies, filed honest — the busywork each team was stuck with, what I built, and the number that changed.
Ten builds for marketing, content and development teams — Slack assistants, QA robots, ticket automations, content-gap engines, client shortlisting, leave requests, post-deploy QA — each filed with the problem it retired and the result it left behind. Pull a file to see how each build earns its keep in a real workflow.
2026 · Dev + Marketing — A release's blast radius was guesswork, and CMS edits never showed at all. Now every deploy hands over the exact pages to check, each tagged with what to do, and logs them to a searchable changelog.
2026 · Marketing Team — A filed leave sat in HR records nobody watched until someone was already out. Now filing tags the approver, the team is warned in time to sort cover, and both calendars keep themselves.
2026 · Marketing Team — The rules for which client site could be featured lived in one person's head. Encoded, one question now reaches roughly 5,900 live sites instead of forty-odd.
2026 · Marketing Team — Change one template on a site with hundreds of pages and you can't eyeball them all. Hundreds of pages, re-checked in one unattended run.
2026 · Marketing Team — Your team's knowledge lives in seven places. 7 sources, one Slack DM, no digging.
2026 · Marketing Team — Every Friday, MARA hands each teammate an honest recap of what they actually moved. ~12 recaps, one honest read each, every Friday.
2026 · Marketing Team — The team drops marketing requests in a Slack channel. 1 message, a whole ticket tree, built and tracked.
2026 · Writers Department — Run SEO across several clients and no two gap analyses are alike. 6 months of editorial calendar, per client.
2026 · Agent Image — Campaign pages meant hand-coding the same sections over and over. Hours, not days, to build a new on-brand block.
2026 · Marketing Team — Every weekday morning, before the team logs on, MARA posts one brief to their Slack. 5 mornings a week, the morning scan, done before you log on.
