• 🔹Coordinated with Cloud & Infra teams for DR drills, SSL certificate renewals, OS patch sanity checks, and overall environment readiness.
• 🔹Resolved API failures related to KYC, eSign, Funding, and Core Banking integrations by validating payloads, reprocessing stuck requests, and working with third-party vendors.
• 🔹Executed SQL-driven data corrections for loan workflow failures, routing mismatches, and backend inconsistencies to restore broken transactions.
• 🔹Handled UI issues like dropdown failures, stale data, and caching errors by performing master cache refresh and post-patch validations.
• 🔹Monitored and troubleshot jobs/schedulers, automated restarts to prevent patching-time failures, and ensured smooth daily processing.
• 🔹Restored user access via LDAP sync, fixed directory mismatches, and resolved authentication-related escalations.
