Karen Onaly Bautista Terrero

I’m a software engineer with 6 years of experience designing and developing enterprise software, web platforms, REST APIs, and mobile applications from concept to production. I work end-to-end with clients to define technical requirements and turn specifications into production-ready solutions.

At UTREEE, I designed relational database models and implemented scalable REST APIs for financial, audit, billing, reporting, document management, and administrative workflows. I also developed backend services and web applications, then handled deployments, monitoring, infrastructure issue resolution, and performance optimization.

I enjoy solving complex technical challenges and delivering reliable systems across healthcare, government, finance, retail, and business management. Through backend and database optimization, I reduced execution time of a critical business process from approximately 20 seconds to under 5 seconds, while collaborating through code reviews and technical guidance for junior developers.
