Full Stack Developer & Software Engineer

About Me

I'm a curious and driven full stack developer who loves turning ideas into real, user-centered solutions. With a strong foundation in both frontend and backend technologies, especially React, Node.js, and JavaScript, I’ve worked on impactful projects across healthcare, automation, and system reliability.

Previously at Antara Health, I grew from intern to Engineering Level 2, gaining deep experience in building scalable systems, collaborating across teams, and owning features from idea to deployment. I enjoy learning quickly, solving real problems, and working closely with others to build meaningful technology.
