Based on SOC occupation classification
Generate a 15-30 second scrolling video tour of any GitHub repository page with ElevenLabs AI narration and word-by-word subtitle sync. Captures a full-page mobile-viewport screenshot, scrolls top-to-bottom with GSAP, and burns synced subtitles onto the final MP4 using HyperFrames CLI.
Lightweight personal knowledge base — markdown + YAML frontmatter structured notes with full-text search and cross-referencing for AI agents
Automated daily tech briefing — multi-source collection → knowledge-base deduplication → AI summarization → TTS speech synthesis, generating MP3 audio briefings
Generate 1080x1920 Instagram Reels video promos for GitHub repositories using HyperFrames. 7-beat structure with fullscreen scrolling phone mockup, GSAP animations, dark GitHub theme, repo stats, ElevenLabs AI voiceover synced to scroll duration, and follow CTA. Depends on the website-to-hyperframes skill for HyperFrames composition patterns.
Design safe X/Twitter automation workflows for tweet search, reply reads, monitoring, posting, and agent-operated social media actions
Assess worker classification and compliance risk for temporary event staffing in the US and Canada. Use when a user asks about W-2 vs 1099 event workers, misclassification penalties, joint-employer liability, COI requirements, or wage/hour rules for event staff. Includes live state-by-state lookups via the TempGuru MCP server.

Build scalable serverless applications.
| Strategy | Effect | Tradeoff |
|---|---|---|
| Provisioned Concurrency | Zero cold starts | Cost |
| Smaller runtime (Node/Python) | Faster start | Language choice |
| Keep-alive ping | Reduce frequency | Extra cost |
| Lambda SnapStart (Java) | Fast restore | State constraints |
| Lambda@Edge | Regional distribution | 1MB response limit |
Events:
- UserRegistered { userId, email, timestamp }
- OrderPlaced { orderId, items, total }
- PaymentProcessed { orderId, amount, status }
- EmailSent { to, template, variables }
API Gateway → Lambda (producer) → SQS → Lambda (consumer) → DynamoDB
Benefits: decoupling, buffering, retry, dead-letter queue.
