Matheus P.

I’m a Senior Full Stack Developer with strong hands-on experience building, improving, and maintaining scalable web applications and APIs. My core stack includes React, Next.js, TypeScript, Node.js, AdonisJS, PostgreSQL/MySQL, AWS, Docker, and Git. I work across the entire development lifecycle — from designing features and APIs to implementing frontend interfaces, integrating services, debugging complex issues, optimizing performance, and maintaining existing codebases. I have experience working on real-world products involving SaaS platforms, network management systems, payment-related workflows, real-time applications, and business-critical APIs. I’m comfortable joining an existing project, understanding its architecture, and delivering changes without unnecessarily complicating the codebase. I also actively use AI-assisted development tools such as Claude Code and similar solutions to accelerate development, research, debugging, and refactoring. I believe AI is most valuable when combined with strong engineering judgment, so I always review and validate generated code for correctness, maintainability, security, and consistency with the project architecture. My approach is pragmatic: clean code, clear architecture, maintainability, performance, and solving the actual business problem rather than overengineering. I’m available for long-term remote projects as well as focused freelance engagements where I can contribute as a hands-on senior engineer.
