Frontend Developer with over 3 years of commercial experience.
Proven experience in delivering projects from inception to production, ensuring high-quality, scalable, and
maintainable code. I’ve worked both independently as a sole developer and collaboratively within cross-functional
teams. I am seeking a Frontend Developer role where I can apply my expertise, contribute to impactful solutions, and
continue growing within a collaborative and innovative environment.
