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.

Design efficient, scalable database schemas.
| Normal Form | Rule | Violation Example |
|---|---|---|
| 1NF | Atomic columns, no repeating groups | phone_numbers: "555-0100,555-0200" |
| 2NF | 1NF + all non-key cols depend on full PK | Orders table with product details |
| 3NF | 2NF + no transitive dependencies | Employee with department_name (dept info in dept table) |
When to denormalize: Read-heavy workloads, reporting, caching layers.
| Index | Use Case | Tradeoff |
|---|---|---|
| B-Tree | General purpose, equality + range | Default, usually best |
| Hash | Equality only | Fast lookups, no sorting |
| GIN | Array/JSON | Slightly slower writes |
| BRIN | Huge sorted tables | Very small size |
