What I'm looking for

I’m looking for a team where I can build and improve data-centric web products, optimize database performance, and enhance user experiences. I want end-to-end ownership in a modern stack (Docker, Git, Jira) with clear goals, SLAs, and continuous learning.

I’m a results-driven Software and Data Engineering student and Full Stack Developer focused on building scalable web applications and managing complex data structures end-to-end. I bring proven experience in the US Healthcare industry, specializing in insurance verification, financial responsibility analysis, and medical data management, with a strong bias toward accurate, reliable outcomes.

I work across the full software development lifecycle—from initial design thinking to production deployment—using Docker, Git, and Jira. I’m skilled in React, Angular, and Vue for frontend development, with Java and Spring Boot for robust backend solutions, and I’m passionate about optimizing database performance, enhancing user experiences, and delivering data-centric digital solutions that teams can measure and improve.
