👋 Hello, I'm

Otávio Baziewicz Filho
Software Engineer

I build high-quality software built to scale. From cluster-based systems to serverless architectures.

About Me

Passionate backend engineer specializing in Node.js and TypeScript, dedicated to crafting well-architected solutions that solve real-world problems with elegance and scalability.

I'm Otávio, a software engineer who specializes in Node.js and TypeScript backend development. I'm passionate about creating solutions from scratch with well-architected code as my core principle.

My expertise lies in implementing robust architectural patterns like Domain-Driven Design (DDD), Clean Architecture, and Hexagonal Architecture. I thrive in startup environments where rapid prototyping meets rigorous engineering standards, creating proof-of-concept software that validates feasibility while maintaining code quality.

Beyond backend development, I design complete application ecosystems - from selecting the right tools and designing cloud architecture to implementing release management and CI/CD pipelines. I believe in building solutions that are not just functional, but maintainable, scalable, and ready for the challenges of tomorrow.
