• Write and optimize SQL in Oracle and SQL Server, working closely with DBAs.
• Build Bash and PowerShell automation and maintain CRON-scheduled batch jobs.
• Create and deploy certificates on Windows and Linux, and coordinate with server and network teams on maintenance and issue resolution.
• Own the full SDLC: requirements, functional and technical specs, test plans, UAT support, change requests, and system documentation.
• Monitor production and non-production environments, resolve tickets, and produce monthly platform reports.
