Hello 👋

I'm Gabriel, a senior full-stack engineer (17+ years) focused on TypeScript, React/Next.js, and Node.js. I build modern web apps and backend services with strong reliability: clear APIs, queues/retries, good tests, and safe deploys.

Recently I've worked 100% with React + Node, shipping Shopify Hydrogen storefronts and backend services for production teams. I also have experience with Vue.js, which helps me ramp up quickly on different UI patterns when needed.

Open to full-time roles (ET) and selective consulting.

About me

Curious about me? Here's a quick story:

I'm a senior full-stack engineer (17+ years) focused on TypeScript, React/Next.js, and Node/NestJS. I build user-facing products and backend services that are simple, fast, and reliable.

Most of my work is end-to-end: shaping the solution with product/design, building the feature, shipping safely, and supporting it in production. I'm strong with integrations and operational work (queues, retries, webhooks, background jobs), and I care a lot about tests, docs, and clean code.

Systems I've built:

E-commerce & Wholesale: Shopify storefronts and internal tools that support real operations.
Manufacturing & ERP workflows: Inventory, sales, assembly, and reporting systems focused on speed and accuracy.
Public sector: Large systems with strict requirements and long-term maintenance.

What people usually notice when working with me: steady delivery, clear communication, high review standards, and mentoring support for developers.

Finally, some quick bits about me.
