Remote · Itabira, Brazil

Senior software engineer, backend-strong (Node.js · TypeScript · PostgreSQL),

Tech Lead experience. Remote-native. Advanced English (C1).

I don't ship toy demos — I fix the things that break in production.

# about.md

I'm Arthur — a senior engineer based in Itabira, Brazil, working remotely for ~4 years.

Backend-strong but genuinely fullstack (Node.js, TypeScript, PostgreSQL; React / Next on the front).

What I enjoy most is taking a problem end to end: sitting with stakeholders, understanding

the product and its users, designing how the system should work, and building it until it's

solid. Advanced English (C1), remote-native, and available for senior international roles.

Systems I've designed and shipped

~/central-automação — Live · solo founder · 2026

Influencer-affiliate deal automation

Discovers marketplace deals, scores them with a 4-signal engine, generates AI copy and broadcasts to WhatsApp groups at ~600 sends/day. A durable BullMQ + Redis pipeline absorbs ~1,500–2,000 candidates/day across multiple sources, with anti-bot residential egress. Solo: architecture to deploy.

stack: Node.js · TypeScript · Next.js · BullMQ + Redis · PostgreSQL / Prisma · Telegram MTProto · WhatsApp / Baileys · WireGuard · Vercel AI SDK

~/comexdigital — In development · solo

Multi-tenant foreign-trade SaaS

Purchase-order management for Brazilian importing teams, built around automated supplier communication. End-to-end type safety, Prisma multi-schema with automatic org-scoping across 34 models, 22 architecture decision records, and ESLint enforcing the architecture (no db imports in pages, no swallowed errors).

stack: Next.js · tRPC · Prisma 7 · PostgreSQL · better-auth · Tailwind · Stripe

~/Dati platform — Tech Lead · 100+ companies

B2B foreign-trade platform

Led a 6-person squad on a multi-tenant platform: 10+ microservices, DDD + clean architecture, SSO + tenant-based authorization on AWS Cognito. Introduced the team's entire engineering practice (branching, PRs, code review, releases) and reviewed 100% of merged code. Isolated a flaky government integration behind its own microservice so the platform keeps serving when that system is down.

stack: Node.js · C# · AWS Cognito · Lambda · SQS · EventBridge · Microservices

~/NMC · Vale escape-room — Delivered · paid freelance

Real-time corporate escape room

Four web games on tablets driven by an operator dashboard and a TV monitor, ported from Unity. Typed WebSocket events with auto-reconnect, an offline PWA, and a correctness-minded domain (partial-unique active session, first-approval-wins).

stack: Node.js · Fastify · WebSocket · Drizzle / SQLite · React · PWA
