Tools I Built to Build Faster

The tools that build the tools

The capability layer underneath the projects.

Higgsfield Creative/Marketing Studio

A CLI plus four custom skills (generate, marketplace-cards, product-photoshoot, soul-id) used across nearly every project for logos, hero shots, mockups, and social imagery.

VideoStudio

A conversational AI video-editing environment: a video-use skill (transcribe, cut, grade, subtitle via ffmpeg and libass) and a hyperframes motion-graphics skill with 11 sub-skills (GSAP, Lottie, Three.js, WAAPI, and more), plus ElevenLabs Scribe.

Flux

A bilingual PT and EN automation and integration tutor running as a Claude Code persona, with a six-week curriculum from APIs to webhooks to Make, n8n, and Zapier to MCP to AI agents to Python automation.

Agent-squad library

Thirteen specialized AI agent squads (brand, copy, cybersecurity, traffic, advisory board, C-level, design, data, storytelling, and more) that I run multi-disciplinary reviews and builds through.

Multi-brand content-base systems

Two-hundred-post content brains (a 17-column Sheets schema) that let Estelita auto-skin any dropped media to a brand’s voice.

Audits and Research

Security as a gate, not an afterthought

Formal audits, market studies, and the fix lists I closed before go-live.

Security audits

The Compatibility Code Test 1 (four blockers found and fixed, verified complete) and the Eggea Cleaning eight-reviewer deep audit (code, cyber, privacy, and five strategy chiefs) that drove the go-live fix list.

Market research

An Atlanta cleaning market study (a 15-slide deck plus PDF, more than 14 companies) justifying per-square-foot rates.

Marketing production

Eggea and Cleaning by Cris social posts and reels via reusable HTML and PIL render templates (headless-Chrome rendering), Facebook covers, videos and carousels via Estelita, plus multi-channel ad strategies and posting calendars.
