Hi, I'm Mel (Melvin Carmona Ortiz)

I build websites and Shopify stores, using AI coding tools (Claude Code and Codex) and checking their work myself. I founded MCO WebLab in 2025, and I'm studying for a B.S. in Computer Science at Inter American University of Puerto Rico (in progress).

Based in Ponce, Puerto Rico. Bilingual in English and Spanish. Open to full-time web and Shopify developer roles.

Projects

  • Receiving Reader: reads supplier packing slips and invoices (PDFs and phone photos, English and Spanish) with the Claude API, checks them against the purchase order and flags the lines a person should look at. On 18 made-up test documents it read 918 of 918 fields correctly. TypeScript, React, Zod.
  • Bilingual Inquiry Assistant: reads website inquiries in English or Spanish and returns checked JSON (service, budget, urgency, draft reply) using the Claude API. 28 of 29 right on a real accuracy test. TypeScript, Zod.
  • Receiving & IT Asset Dashboard (live demo): stock receiving and IT asset tracking on Postgres (Supabase) and Next.js, with SQL joins, views, a read-only role and row-level security. Made-up data.
  • MCO WebLab MCP Server: gives Claude tools to price website projects, recommend sizes from a size chart and help with IT support checks. TypeScript, MCP.
  • MCO Size Chart Theme: a Shopify Dawn theme with a reusable size chart section driven by metaobjects, inches/centimeters switching, English and Spanish text, and GA4 events through Google Tag Manager. Theme Check and automated tests run in GitHub Actions.

Client work (live sites)

Client code stays private.

Skills

HTML, CSS, JavaScript, jQuery, Shopify (Liquid, Online Store 2.0 sections, metafields), WordPress, Webflow.
