Vinicius Santana

I’m a Fullstack Developer with 5+ years of professional experience building scalable web applications across JavaScript and Ruby ecosystems. I focus on shipping production-grade Node.js services, React interfaces, and REST APIs, with a strong foundation in TDD, agile delivery, and full-stack architecture.

At PureSpectrum (Remote, United States), I developed and maintained Node.js backend services for a US-based SaaS platform and built React-based frontend components integrated with REST APIs. I engineered a proprietary Kotlin SDK from the ground up to enable third-party integration and expanded the developer ecosystem, while implementing comprehensive automated test coverage to reduce regression bugs and improve deployment confidence.

Before that, at Repassa (São Paulo, Brazil), I contributed to backend and API development for a circular fashion e-commerce platform—supporting product listing, inventory management, and checkout flows. I also delivered custom solutions at Delivery Center, building and integrating RESTful APIs with an emphasis on performance, reliability, and maintainability, plus collaborating through code reviews and best-practice documentation.

I started early at Quasar Flash, helping build the core product from the ground up by implementing authentication, role-based access control, and background job processing. I enjoy collaborating daily with cross-functional teams across time zones and consistently use test-driven development to support confident refactoring.
