- Ensure compliance with best practices in web security, including encryption, CSRF / XSS protection, and API access control.
- Build core frameworks and reusable modules that enable other developers to work efficiently and maintain consistency across the codebase.
- Design and implement core logic for multi‑vendor marketplace systems, including vendor onboarding, catalog management, and secure transaction flows.
- Lead architectural decisions that improve system reliability, scalability, and performance.
