• Participate in peer code reviews and team knowledge‑sharing.
• Diagnose and resolve defects, performance issues, and cross‑platform inconsistencies.
• Stay up‑to‑date with industry trends, frameworks, and emerging best practices.

Required Skills & Qualifications

• 5+ years of experience in Full‑Stack Development with React and Node.js.
• Hands‑on experience with React Native and mobile application lifecycle.
• Experience preparing builds and publishing apps to the App Store and Google Play.
• Strong proficiency in JavaScript/TypeScript.
• Experience with RESTful APIs, microservices, and both SQL/NoSQL databases.
• Familiarity with Git and modern CI/CD practices.
• Experience building and maintaining unit tests.
• Experience with cloud providers (GCP preferred; AWS/Azure welcome).
• Understanding of Agile methodologies.

Soft Skills

• Strong ownership mindset and leadership qualities.
• Excellent communication skills in English.
• Ability to collaborate across product, design, and engineering teams.
• Comfortable operating in a fast‑paced environment.
• Ability to take projects end‑to‑end with minimal supervision.
