👋 Hola, soy Marco — Full-Stack Engineer

Next.js + TypeScript + AI workflows
I design & ship SaaS that feel fast, human, and scalable.

• 🧠 10+ yrs building for finance, education, e-commerce & SaaS
• ⚡ Next.js/React + Prisma + Supabase + Stripe for multi-tenant platforms
• 🤖 AI-assisted development (Claude Code, Cursor, ChatGPT, v0) → faster delivery, fewer bugs
• 📈 Analytics-driven: instrumented 100k+ daily events with Mixpanel
• 🛠️ Led migrations (DB2/legacy → modern stacks) and mentored teams

I treat AI like a pair-programmer to ship high-quality work today—not someday.

• Spec → Code: Claude Code / ChatGPT for RFCs, edge cases, tests
• Code → Review: Cursor for refactors, dead-code pruning, DX improvements
• UI/UX: Vercel v0 prompts for UI drafts, then hand-tuned with Tailwind + shadcn/ui
• Data & Product: Mixpanel event design, funnels, feature-flagged rollouts
• Reliability: AI-generated test scaffolds (Playwright/Vitest), contract tests for APIs
