• Create custom themes/plugins/components where needed (PHP, JavaScript, Twig, or similar templating languages).
• Train non-technical team members on CMS workflows and best practices (content creation, SEO fields, media management).
• Continuous Improvement:
• Monitor site analytics, page-speed metrics, and uptime to proactively troubleshoot and optimize.
• Integrate third-party services/APIs (e.g., payment gateways, chatbots, analytics trackers, marketing automation).

• Architect and maintain real-time database structures (Firestore/Realtime Database) and storage rules.
• Implement authentication (Firebase Auth) for web and mobile apps, integrating social logins (Google, Facebook, Apple).
• Develop serverless functions (Cloud Functions) for business logic, notifications, or data processing triggers.
• Set up and optimize Firebase Cloud Messaging (FCM) for push notifications (promotions, new product launches, account reminders).
• Monitor usage quotas, billing, and performance—scale resources as needed to support increased traffic.
• API Integrations & Security:
• Integrate third-party RESTful or GraphQL APIs (payment gateways, shipping providers, marketing tools).
• Implement secure data rules, encryption, and access controls (Firebase Security Rules, SSL, HTTPS).
• Conduct periodic security audits, code reviews, and vulnerability assessments to ensure compliance with best practices.

• 3+ years implementing Firestore/Realtime DB schemas, Cloud Functions, Auth, FCM, and Security Rules.
• Knowledge of performance tuning, billing management, and serverless best practices.
• General Development Skills:
