Backend Developer
Yago Andrade
Backend developer passionate about scalable systems and clean code. I turn complex problems into robust solutions using any language or framework.
About Me
I'm a backend developer focused on solutions that work and last. I mainly work with Java + Spring Boot and Node.js + TypeScript/NestJS, but I've delivered production code with PHP/Laravel, C#/.NET and even React/React Native when the project needs it. I like solving real problems: less theory, more working software. If you need someone who understands the business, writes code that won't become legacy tomorrow, and delivers on time, let's talk.
Experience
Mid-Level Backend Developer
Marlabs BrasilMay 2025 – Present
- I work on the development and maintenance of UCaaS and CCaaS solutions for CallTower, collaborating daily with a fully American team and handling meetings and documentation in English.
- I focus on integrations across Microsoft Teams, Cisco Webex, and CT Cloud (Graph, Operator Connect, Direct Routing, Webex Calling) and on VoIP architectures using Sansay and Metaswitch carrier-grade platforms.
- I led the development of a robust integration with FaxBack, enabling the virtualization and intelligent routing of 8,000+ legacy fax devices to the cloud.
- This solution removed on-premises dependencies, reduced fax-related support tickets by 92%, and automated processes that previously took 15-40 minutes per incident—saving hundreds of hours per year and accelerating enterprise customer migrations.
