What I'm looking for

I am looking for opportunities that foster innovation and collaboration in fintech development.

I am a full-stack software engineer with over four years of experience in building scalable web applications and APIs. My journey has been marked by a strong focus on developing B2B fintech solutions that serve over 40,000 users across Latin America. I have successfully led migrations from monolithic systems to microservices architectures, leveraging my proficiency in JavaScript, Node.js, React, and AWS cloud technologies.

At Xepelin, I played a pivotal role in developing fintech solutions using React and Node.js, while also leading serverless application development with AWS Lambda. My commitment to implementing Clean Architecture and Domain-Driven Design principles has significantly enhanced code maintainability and system flexibility. I am recognized for my strong problem-solving skills and my passion for delivering secure, high-performance solutions that meet the needs of users and stakeholders alike.
