What I'm looking for

I am seeking a role that fosters innovation, collaboration, and growth opportunities in technology.

I am a dedicated back-end developer with a strong focus on API integration and automation. Currently, I am working remotely as a Back-End Developer at Contact Center Specialists, where I engineered a high-throughput telecommunications inventory platform that optimized critical workflows significantly. My expertise in concurrency patterns and database management has allowed me to deliver high-performance solutions that enhance operational efficiency.

In addition to my current role, I have experience as a Lead Developer for a Women Empowerment Platform, where I architected a Learning Management System that supports multiple user roles and enables seamless course management. My commitment to delivering robust and scalable applications is evident in my work, which includes implementing zero-downtime CI/CD processes and ensuring high availability. I am passionate about leveraging technology to drive positive change and empower users through innovative solutions.
