Benjamin Zuniga Sanchez

• Day-to-day work spans complex integration failures across the ServiceNow platform for enterprise customers, carrying cases from ambiguous symptoms to documented root cause.

• Experienced across Vulnerability Response integrations with Rapid7, Qualys, and Tenable, where most cases that look like bad data trace back to CI correlation or scan deltas, such as missing CVE data in a delta payload leaving vulnerable items unable to close.

• Well-practiced with authentication failures across SSO/SAML, LDAP, and MFA, along with email-delivery issues spanning SMTP, IP reputation, and DNS records.

• Equally comfortable with proxy/firewall and connectivity problems, down to TLS/certificate validation and REST API connectivity.

• Splunk is a primary tool for tracing root cause through distributed application logs (authentication handshakes, certificate validation, API connectivity), then turning those findings into peer-to-peer technical analysis for enterprise customers.

• Delivered Senior support to enterprise customers running Azure API Management, Batch, Cloud Services, and Storage, with a focus on securing API gateways, hardening private network connectivity, and protecting service reliability through safe change.

• Secured and stabilized API Management private connectivity across virtual networks, Private Endpoints, DNS, network security groups, and route tables, removing public exposure and resolving the dependency and configuration issues behind latency and timeouts.

• Authored runbooks for API Management upgrades and safe virtual network detach and reattach, with verification and rollback steps to keep changes safe and reversible, and documented recurring Batch and compute fixes in a known error database.

• Built Python and PowerShell utilities to validate network and security configurations and parse logs, speeding triage and catching misconfigurations early.

• Troubleshot issues end to end across backend, networking, and configuration, validating TLS certificates, API endpoints, and identity using openssl and Azure Log Analytics with KQL.

• Hardened Windows Server baselines using Qualys vulnerability scans, raising compliance and standardizing secure configurations across large, multi-server Windows estates.

• Planned and executed staged Windows Server migrations from 2012 to 2016 and 2019, with change validation and rollback plans that minimized downtime, and implemented backup and disaster recovery procedures validated through RPO/RTO restore tests and recovery drills.

• Diagnosed connectivity and performance issues using packet capture and network analysis (Wireshark, Nmap, nslookup, curl, and openssl), and automated recurring server and network maintenance with PowerShell and Jenkins to cut manual effort.

• Provisioned secure devices and supported Windows/Active Directory environments, improving first-contact resolution.

• Drove Scrum delivery (sprint planning and reviews, definition-of-done) and improved stakeholder visibility through concise status, risk, and action logs.
