• Designed, implemented, and administered 6 ETL/ELT pipelines, utilizing Google BigQuery, MSSQL, PostgreSQL, Shell scripting, PL/pgSQL, and Transact‑SQL, integrating data for efficient Python API processing.
• Built fail‑closed abuse controls — 22 Redis‑backed rate limiters, Cloudflare Turnstile, request idempotency and an origin lock — so the platform sheds bots and floods instead of trusting its callers.

This work is part of what we offer as Backend & API Development, Data Pipeline Development (ETL/ELT), Data Warehouse Design, Database Design & Modeling, Security & Access Management and Site Reliability & Monitoring.
