Matheus Abrahao

Senior Full Stack Engineer

React * Next.js * Node.js * TypeScript * Shopify

I build web products that convert -- and scale. $90K+ in e-commerce revenue and counting.

About

Full Stack Engineer with 5+ years shipping production systems. I own products end-to-end -- from database schema to checkout flow to deploy pipeline.

I built and operated an e-commerce platform that generated US$90,000+ in sales. Not a side project. A real business with real customers, real payments, and real uptime requirements.

Currently focused on React/Next.js frontends, Node.js backends, and e-commerce systems (Shopify, headless commerce, custom integrations).

Highlights

  • $90K+ online revenue delivered for a retail business
  • 40% faster page loads after performance optimization
  • 60% reduction in manual order processing via custom tooling
  • 99.9% uptime during peak traffic windows

Tech Stack

Frontend React * Next.js * TypeScript * Tailwind CSS * Responsive Design
Backend Node.js * Express * REST APIs * GraphQL * Webhooks
Databases PostgreSQL * MySQL * Prisma * Redis
E-commerce Shopify (Liquid, Hydrogen, Storefront API) * Payment Gateways * CRO
Infrastructure Vercel * Docker * GitHub Actions * CI/CD * AWS * Firebase

What I Build

E-commerce Platform -- $90K+ Revenue

Problem
A retail business needed a high-converting online store with custom checkout logic, inventory sync, and room to scale.

Solution
Built the full stack: React/Next.js storefront, Node.js backend, Shopify integration, payment processing, and an admin dashboard for orders and inventory. Optimized for speed, SEO, and conversion.

Impact

  • $90,000+ in total online sales
  • 40% faster page loads after frontend optimization
  • 60% reduction in manual order processing
  • 99.9% uptime during peak traffic

How I Work

+----------------------------------------------------------+
| - Own it end-to-end. Architecture to production. |
| - Ship for impact, not for show. |
| - Write code that survives the next feature. |
| - Communicate async. Work remote. Deliver on time. |
