• Database Expertise: Strong practical background with Microsoft SQL Server (T-SQL), including schema design, query tuning, transaction management, and indexing.
• API Development: Proven experience building and consuming secure RESTful APIs, handling token‑based authentication (OAuth 2.0), webhooks, and rate‑limiting protocols.
• Zoho Platform Integration: Demonstrated experience extending the Zoho platform via Deluge, Zoho REST APIs, custom functions, or Zoho Flow.
• Tools & Practices: Solid command of Git version control, CI/CD pipelines, and secure coding practices.

Preferred Qualifications
