How I work

I orchestrate AI agents.

I have written 3,800+ task specs for human teams, and the same habit now drives coding agents. I split the work, set the checks, review what comes back and decide what ships. When a plain script beats an agent on cost, the script wins.

Tools I built & operated

Subscription cohort forecasting for acquisition reviews

Built a forecasting tool that imports RevenueCat, Adapty, and Apphud cohorts, models weekly, monthly, and annual subscriptions, and exports revenue, profit, ROI, and acquisition-price scenarios. Includes a no-new-subscriber mode and checks for incomplete retention data and unverified subscription mixes.

AI-powered SMM content pipeline

n8n plus LLM workflow for multi-platform, multi-language publishing with a group-command interface; replaced an external content vendor.

Agent-run case-video pipeline

Vertical case videos rendered with Remotion and FFrames, with ElevenLabs narration, speech-timed captions and a music mix. A coding agent turns a plain-language scenario into a finished video, choosing assets and recording their sources.

Agentic event-collection pipeline

n8n agent that keeps Approck’s conference directory current: Claude Haiku re-checks tracked event pages weekly, and Claude Sonnet with web search finds new conferences monthly. A Symfony API removes duplicates before results reach the directory.

Agency ops platform (internal)

Project-estimate tracker plus Slack bots for bench tracking, missing-report chasing, and team activity analytics — internal tooling that ran delivery operations for an agency of roughly 40 people.
