Hello! I’m Karen Onaly Bautista Terrero, a full-stack developer focused on building production-grade web portals, REST APIs, and mobile-connected solutions for corporate and public-sector environments. I’m proficient in JavaScript/TypeScript, Node.js, React/Next.js, Angular, PostgreSQL, MySQL, Redis, and AWS services such as Lambda, S3, IAM, API Gateway, and EC2. I enjoy transforming complex data workflows (JSON/XML/CSV) into clean, scalable backend and API integrations. Over 5+ years, I’ve delivered maintainable products, optimized backend performance (reducing load times from around 20 seconds to under 5 seconds), and collaborated in Scrum teams. I’m always eager to learn and apply best practices for reliable, secure software delivery.…Hello!
