About

Professional summary

I am a Senior Software Engineer with over 8 years of experience building scalable digital products for high-traffic platforms.

My background is centered on full-stack and frontend development, with strong expertise in React, Next.js, Node.js, TypeScript, and serverless architecture. I have worked extensively on e-commerce, ticketing, and support platforms where reliability, performance, and fault tolerance are critical.

I have contributed to projects that process thousands of daily transactions and serve millions of users, focusing on architecture, API development, database design, and production stability. I also have hands-on experience with modern engineering practices such as automated testing, CI/CD, micro-frontends, and observability-oriented implementation.

In recent roles, I have worked remotely with US and Brazilian teams, collaborating closely with product, design, and engineering stakeholders to translate business needs into robust technical solutions. I am comfortable operating across the full development lifecycle, from planning and implementation to deployment and support.

I actively use AI-assisted development tools such as Claude Code and Cursor to accelerate implementation, testing, documentation, and code review. I also build automation workflows with n8n to improve delivery efficiency and engineering productivity.

I am currently pursuing an MBA in Strategic IT Management at PUC Minas, preparing for technical leadership responsibilities. I am fluent in English and Portuguese, and I value clear communication, ownership, and delivering high-quality software on time.
