Professional Profile

Dual-track professional with 25+ years in the music industry and an active second specialty in software engineering built with AI as co-pilot. Elite Music Producer, Podcaster, and Author; senior expert in Mixing and Mastering (Pro Tools, Logic Pro, Ableton Live). In parallel, designs and operates full-stack production systems —financial dashboards, REST APIs, MCP servers, agent infrastructure, and automation pipelines— integrating large language models (Claude, Gemini, GPT) with real services (Notion, Google Workspace, Cloudflare, Firebase). Combines commercial vision, advanced audiovisual mastery (Final Cut Pro, OBS), and a mature AI-assisted development practice focused on solving concrete business problems, not throwaway prototypes.

AI-Native Software Engineering

Full-stack developer who leverages AI as a co-pilot to build and operate real production systems. Beyond "using ChatGPT", designs architecture, integrates services, runs infrastructure, and solves concrete day-to-day problems.

Production Applications

  • Finance Dashboard (v7.8.x) — Household financial planning dashboard with multi-currency MXN/USD support and Cetes/Bitcoin tracking. Vanilla JS + Vite, serverless backend on Cloudflare Workers, Google Sheets as data source. Deployed on GitHub Pages and in daily use for 8+ months.
  • Manager App (v1.1.x) — Mobile-first app for music catalog and career management. React + Howler.js, Cloudflare Worker backend, Notion as database, Google OAuth, and secure audio streaming from Google Drive via Service Account.
  • Finance v2 API Server — TypeScript REST API (Fastify + zod + sql.js) powering Dashboard and Manager App. Daemonized on macOS with LaunchAgent (KeepAlive); secrets stored in macOS Keychain (no `.env` files in the repository).
  • Finance MCP Server — Model Context Protocol server in Node.js + Fastify, deployed to Fly.io. Dual transport (HTTP + stdio), consumed simultaneously by Claude, Gemini, and native iOS widgets.
  • Elussila Gallery — Art gallery in Next.js 16 + Firebase with Google Drive OAuth upload flow. Deployed on Vercel.
  • MK Composer (v1.0.x) — Songwriting-assistant PWA powered by Groq/LLaMA, with Google OAuth and Google Sheets as catalog backend.

AI Infrastructure & Agent Systems

  • Multi-AI persistent memory (Engram) — SQLite system with observations, topic keys, and relations (supersedes / conflicts / scoped) shared across Claude Code, Gemini, OpenCode, and ChatGPT on different machines. Lets any agent recover context and decisions from any other.
  • 40+ modular agent skills — Custom capability library for Claude Code and Antigravity featuring sub-agent delegation, orchestration, and controlled context switching.
  • End-to-end Spec-Driven Development — Explore → propose → spec → design → tasks → apply → verify → archive workflow, with artifacts persisted in memory and per-change traceability.
  • Multi-model coordination — Claude + Gemini + OpenCode operating on a single SQLite as source of truth, with no retraining and no proprietary cloud services.

24/7 Production Automations

  • Morning and evening briefings (Python) — Aggregate Gmail + Notion + Google Sheets and deliver a digest via Notion, Telegram, and native macOS notifications.
  • Telegram receipt bot — OCR + vision, evidence archived in Google Drive, itemized records in Sheets for granular spend analysis.
  • Automated video pipeline — ffmpeg + Whisper + AI highlight selection + YouTube API → automatic Shorts publishing.
  • OpenCode ↔ Telegram bridge — Remote control of Claude Code from mobile.
  • Cloudflare Workers as authenticated proxy between apps and Notion/Drive.

Applied Engineering Patterns

  • *Evidence-first ledger* — every financial transaction requires a verifiable artifact before being recorded.
  • *Stateless secrets* — credentials in macOS Keychain, never in repository files.
  • Event-driven *webhook bridges* for service synchronization.
  • Hybrid architecture: edge compute (Cloudflare) + serverless + SQLite as persistent backend.
  • Full OAuth flows (Google Drive, YouTube, Gmail, Calendar) in both browser and backend.
