What I'm looking for

I am looking for a role that emphasizes backend development and problem-solving in a collaborative environment.

I am a dedicated software engineer with a strong focus on backend development, automation, and internal tooling. My recent experience at IBM allowed me to enhance system performance and streamline developer processes through effective scripting, data modeling, and setting up QA/test environments. I thrive in SQL, PHP, and Linux environments, with a particular comfort in Java. Currently, I am expanding my full-stack development skills and Python fluency through a personal project, which reflects my commitment to continuous learning and improvement.

During my tenure at IBM, I successfully improved database query performance by 30% and automated code release steps, significantly reducing developer workload. My internship experiences at Google further honed my skills, where I contributed to reducing data size in core systems and developed an indie music promotion app. I am passionate about leveraging technology to solve complex problems and am eager to bring my expertise to a role focused on backend work, scripting, or technical support.
