Ecommerce & Brand Specialist

I build brands that stand out and systems that sell.

I work across marketing, design and automation — and I use AI as part of how I build, not just talk about it. I design the UI/UX, then build it myself directly in Shopify, using AI-assisted development to move faster without cutting corners.

Core Capabilities

Four disciplines, one operator.

There's no hand-off between design, code and growth — I do all three myself, so nothing gets lost in translation between what's designed and what actually ships.

01
Commerce

Shopify & Custom E-commerce

I build custom Shopify storefronts — Liquid, HTML and CSS, with AI doing the heavy lifting on implementation. No off-the-shelf themes: every store is built for how it actually needs to convert.

  • Shopify 2.0
  • Liquid
  • Headless
02
Retention

Retention & Email Marketing

Klaviyo flows and campaigns that bring customers back — welcome series, abandoned cart, post-purchase. Email marketing built to move revenue, not just open rates.

  • Klaviyo
  • Lifecycle
  • LTV
03
Identity

Brand Identity & UI/UX

I design brand systems end to end — logo, packaging, digital interfaces — built on the design fundamentals I studied at university and applied to brands that actually need to scale.

  • Systems
  • UI/UX
  • Packaging
04
Automation

AI & Workflow Automation

I connect Claude, Gemini and Make to cut out repetitive work — so campaigns ship faster and less time goes into busywork.

Methodology & Stack

One system, four engines.

Design, code, growth and AI orchestrated as a single stack. Tap any cluster — the workspace re-compiles in real time.

The Architect

Portrait of Sebastián Jara, e-commerce developer and UI/UX designer

Designer by training. Builder by habit.

I'm Sebastián — a graphic designer by training who ended up building the things I design, not just handing them off. I studied design formally, but most of what I do day to day is Shopify builds, brand systems, and workflows that used to take a team and now take me and a few AI tools. I care more about whether something actually works than whether it looks good in a deck.
