* Translate UI/UX designs into clean, efficient, and maintainable code.
* Optimize applications for performance, accessibility, and scalability.
Full Stack Collaboration
* Work closely with backend engineers to integrate APIs and data services built in Java Spring.
* Understand backend concepts (RDS, AWS Lambda, microservices) to effectively design front‑end integrations.
* Contribute to defining and improving the overall architecture of the platform.
Software Quality & Delivery
* Participate in code reviews, sprint planning, and agile ceremonies.
* Ensure code quality through testing, documentation, and CI/CD practices.
* Work in a collaborative, fast‑paced environment where innovation and precision matter.
About You – Qualifications
* 2–3 years of experience in full stack or front‑end development roles.
* Proven experience in mobile and web app design and development.
