CORE COMPETENCIES

Backend Systems Architecture · System Integration & Data Flow · API Design (REST) · Cloud Infrastructure (AWS) · Integration Engineering · Python Backend Development (15+ years) · Async Programming & Concurrency · Infrastructure Automation · AI/LLM Integration · Remote Collaboration (US/EU/CA teams) · English (Professional - daily use)

SUMMARY

Senior Python backend developer based in Brazil (UTC-3), open to fully remote roles with US, EU, and CA teams.

Building software since the early 2000s, with the last 15 years entirely focused on Python and backend systems.

Experience spans CRM, e-commerce, fintech, marketing, and business intelligence, mostly with small and medium-sized companies that needed senior-level thinking without the overhead of a large agency.

Current work centers on backend APIs, AI-assisted development workflows, and infrastructure automation. On the application side: FastAPI, Flask, and Django. When work moves closer to infrastructure: Linux, Docker, Terraform, and AWS, always with an eye on keeping hosting lean and cost-effective. Multi-model LLM agents (Claude, OpenAI, Deepseek, MiniMax) are integrated into the development workflow to move faster without sacrificing code quality.

Works independently and communicates clearly in English.

If you need a Python developer who takes backend systems from code to deployment to production monitoring without losing sight of cost and scale, is comfortable owning the infrastructure layer alongside the application layer, has a highly optimized terminal workflow with tmux, a modern heavily customized Neovim with years of sharpening, and AI coding agents with multi-model capabilities, and ships with both speed and financial accountability, I would genuinely enjoy a conversation.
