What I'm looking for

I seek a collaborative team where I can mentorably grow, work on full-stack web and mobile projects, and contribute to well‑engineered, user-focused products.

I am a passionate full-stack developer with a strong freelance background, skilled at translating ideas into production-ready web and mobile applications. I enjoy tackling challenging problems and producing clean, maintainable code.

My experience includes internships and contract projects using React.js, React Native, Django, Node.js, and WordPress, where I delivered responsive sites, e-commerce platforms, and mobile apps while collaborating with small teams and mentors.

I seek to join a professional environment where I can learn from experienced engineers, contribute to meaningful products, and continue growing beyond self-directed learning.
