• Caching & Distributed Systems: Redis (Pub/Sub, caching layers, distributed locking via Redisson).

Frontend & Mobile Engineering

• Mobile: React Native, Expo, native bridge integration, and mobile UI performance optimization.
• Tooling & CI/CD: Git, GitHub Actions/GitLab CI.

Qualifications

• Experience: 4+ years of hands-on software engineering experience building production-grade, distributed web and mobile applications.
• Education: Bachelor’s or Master’s degree in Computer Science, Engineering, or a related technical field (or equivalent practical experience).
• Soft Skills: Strong problem-solving abilities, excellent technical communication, and a self-driven attitude in a fast-paced product environment.
