Christopher is ready for their next project!
E-commerce automation stack for a Shopify DTC brand. Review request pipeline (Shopify orders API → Spacemail IMAP drafts), abandoned cart follow-ups, and real-time inventory sync between 3PL and storefront. Replaces manual customer-ops work with scheduled scripts running on a cron. Full ownership — no SaaS subscription, no per-seat pricing.

Personal AI executive built on Claude Code. Persistent memory system, portfolio-level task board, expert brief routing, and session-start and session-end reconcilers. Replaces scattered to-do apps with a single conversational interface that knows the business, the priorities, and the failure patterns. Production system I run daily.

Meta Ads campaign orchestration via the Marketing API. A single script wires creative (video, thumbnail, copy), targeting (stacked-interest audiences, device and placement filters), and kill-gate tripwires (spend, ATC, and landing-page-view thresholds) into paused campaigns, ready to activate on command. Built for a Stage-1 DTC brand running cold acquisition on a $10 to $15 per day budget.

Content automation pipeline for a supplement brand. 50 branded pins generated via Sharp and SVG overlay on source imagery, auto-scheduled to Pinterest through a custom Playwright scheduler. One config file, 50 pins queued in a single run, UTM-tracked per board. Replaces a $40/mo SaaS scheduler with a fully owned stack.
