Hi, I'm Arthur 👋

I build services, integrations, automation tools and API-driven products.

About me

Backend engineer with ~3 years of commercial experience.

My main focus is building backend systems with Node.js, TypeScript, NestJS and Express.
I have worked with microservices, REST APIs, Redis, RabbitMQ, SQL optimization, CI/CD, production incidents and internal automation.

I enjoy solving problems where backend is not just CRUD, but a system with real constraints:

• integrations with external services
• queues and background jobs
• performance bottlenecks
• database optimization
• automation of manual processes
• production support and monitoring

Currently improving my skills in system design, live coding, automation platforms and realtime systems.
