Original concept created for this portfolio
- 01
Brand system · Art direction
A distinctive brand experience
The visual system, hierarchy and art direction give the store its own identity instead of making the brand fit a generic template.
- 02
Product page · Ecommerce UX
A clearer product page
Benefits, product information and the primary action are organized so customers can understand the offer and decide with less friction.
- 03
Cart drawer · Conversion
A cart designed to convert
The cart makes the order, progress and next step immediately clear while leaving room for relevant offers without overwhelming the customer.
- 04
Performance · Frontend engineering
Better storefront performance
Intentional JavaScript, deferred assets and fewer dependencies keep the experience responsive and the path to checkout lighter.
- 05
Theme editor · Easy management
Editable from Shopify
Custom sections remain practical for the team: content, order and key options can be managed directly from the theme editor.

Why work with me
Built like a product. Managed like Shopify.
Custom engineering shouldn't make your store harder to run. I build flexible storefronts that stay fast, maintainable and editable by your team.
Clearer buying journeys
Store changes are shaped around what shoppers need to understand, choose and do next.
Speed with a business reason
Performance work focuses on reducing friction between your customer and checkout.
Editable from Shopify
Custom sections and features stay practical for the team running the store day to day.
Less app dependence
When a focused feature can replace another storefront app, the store stays leaner and easier to manage.
Frequently asked questions
What you may want to know before we start.
Clear answers about scope, store management, timing and how a Shopify project begins.
01Can you work on an existing Shopify store?
Yes. I can improve a focused part of your current store—such as a product page, cart, custom section or performance—without rebuilding everything. I first review the theme, apps and current limitations to define the right scope.
02Do you also build complete Shopify stores?
Yes. I develop complete storefronts shaped around the brand, product catalog and buying journey, with a mobile-first experience and practical content management from Shopify.
03Will the custom sections remain editable from Shopify?
That is the goal. I build sections and features with settings and blocks in the theme editor so your team can manage routine content changes without touching code. The exact controls are agreed as part of the scope.
04Do you work with clients in other countries?
Yes. I work remotely from Argentina and can collaborate with brands and teams in different time zones through clear written communication, defined milestones and regular progress updates.
05Do you provide support after launch?
Each project can include a post-launch support period for adjustments related to the delivered scope. Ongoing improvements or maintenance can also be defined separately when the store needs continued support.
06How are budget and timeline defined?
After reviewing what you need, I propose a clear scope with deliverables, timing and cost. A focused improvement and a complete storefront require very different plans, so the estimate is based on the actual work rather than a generic package.
Have a project in mind?
