Hi! I'm Emanuel Lázaro.

"Building scalable systems with clean interfaces, robust backends, and measurable outcomes."

📍 Mucambo, Brazil 🇧🇷

About Me

I am a Software Engineering & Computer Science student (2025–2029) focused on high-performance Full Stack development. I work with an engineering vision, combining modern interfaces with robust backends.

My development philosophy is guided by Clean Architecture, Domain-Driven Design (DDD), and SOLID principles. I strive to create code that scales, maintains, and delivers real value, ensuring production-grade ergonomics in every project.

My primary stack anchors on the TypeScript ecosystem (Node.js, React, Next.js, NestJS), while strategically utilizing Python and Go for automation, data workflows, and concurrency-critical services.

I am currently open to Internships and Junior Engineering roles where I can apply modern web development, cloud-native delivery, and applied AI/ML to real-world systems.
