Mario Vicuña

Shopify development, scoped and shipped.

Fixed-scope projects or ongoing work for merchants and agencies. Every engagement starts with a written scope and acceptance criteria, so you know what “done” means before I start.

What working together looks like

  1. 01 — Brief

    A 20-minute call and a written scope with acceptance criteria

  2. 02 — Spec

    Estimate, approach and risks before any code

  3. 03 — Build

    Work on a preview theme or branch; nothing touches live

  4. 04 — Review

    Pull request with self review and checks; you see every change

  5. 05 — Ship

    Release, handover notes and a short video walkthrough

Questions

Do you work on Shopify Plus?

Yes. Checkout extensibility, Shopify Functions, B2B and Markets are part of my regular work.

Can you work with my existing theme and apps?

Yes. I read the theme first, extend it where it is missing something and avoid rewriting what works.

What time zone are you in?

UTC−4. My working hours overlap with the US East Coast and most of Latin America.

Do you work in Spanish?

Yes. Spanish is my native language and my English is C1 (EF SET).
