What I'm looking for

I am looking for a role that values innovation and collaboration, where I can leverage my skills in software engineering and cloud infrastructure to drive impactful projects.

I am a Senior Software Engineer with a strong focus on building high-performance applications using Node.js, TypeScript, and modern architectural principles like Hexagonal Architecture and Domain-Driven Design (DDD). My extensive experience in fast-paced startup environments has equipped me with a deep understanding of industry best practices, enabling me to develop scalable, resilient, and efficient solutions. I am particularly passionate about fostering a robust testing culture, ensuring that my codebases are reliable through unit testing and end-to-end testing.

Throughout my career, I have successfully integrated serverless services on Google Cloud Platform and deployed infrastructure on AWS using Terraform, which has allowed me to deliver robust architectures that meet the demands of modern applications. I thrive in both independent and collaborative remote environments, always aiming to deliver business value and enhance user experiences. My hands-on experience with cloud infrastructure complements my technical skills, making me a valuable asset to any team.
