Senior Full-Stack Engineer & Platform Builder

15+ years building scalable web systems, resilient architectures, and high-impact products. Specializing in the PHP/Laravel ecosystem, React, and end-to-end infrastructure management.

How I build Software

I don't just write code; I design systems built to scale and last. My focus is on maintainability, clean architecture, and solving complex business logic without over-engineering.

Strict Quality Standards

Robust CI/CD pipelines, Project with 600+ automated tests, PHPStan Level 9, Clean Code, and SOLID principles to ensure bulletproof deployments.

End-to-End Ownership

Comfortable handling everything from designing relational databases and messaging queues to deploying and managing bare-metal server infrastructure.

Team & Culture

I thrive in environments that value deep architectural discussions, rigorous code reviews, and continuous learning alongside distributed engineering teams.

Who I am

1

Based in São Paulo, Brazil (UTC-3) — with flexible availability for overlap with US East Coast and European morning hours. I communicate in English at professional proficiency: fluent in written and reading, and confident in spoken communication.

2

I have spent the last decade mastering remote work discipline to stay close to my family. I have the ability to go extremely deep on complex problems, channeling focus into continuous learning and writing for my technical blog.

3

I use AI extensively as a daily copilot to optimize workflows and accelerate delivery. I communicate directly, value radical candor with empathy, and am looking for a team where I can go all-in on a single, global product.
