Production support Engineer @INSPYR Solutions (@Apple, Inc)
Verified
I’m a results-driven engineer with 7+ years of hands-on experience designing, building, and supporting mission-critical systems across fast-paced SaaS and enterprise environments. I’ve honed my skills at companies like Apple (via INSPYR Solutions), Wise Systems, Ascend Software, and United Envelope—where I’ve: Built scalable Python microservices & automation to streamline workflows, slashing manual alert triage by over 50% and accelerating data retrieval by 40%. Owned production support at 99.9%+ uptime SLAs: conducting deep-dive root-cause analyses, collaborating with infra and app teams on permanent fixes, and driving MTTR down through custom Grafana/Prometheus dashboards. Architected & optimized data solutions in PostgreSQL, MongoDB, and SQL Server: designing schemas, tuning queries, partitioning, and implementing IAC (Terraform) for zero-downtime, multi-region Kubernetes deployments. Delivered Level-2/3 support on Windows and Linux stacks—extending legacy VB.NET/C# apps, automating PowerShell routines, and managing Active Directory, DNS/DHCP, Hyper-V, and VPN environments to bolster security and compliance. Whether I’m building CI/CD pipelines that validate and rollback deployments automatically, writing Python scripts to automate end-to-end support tasks, or analyzing logs/packet captures to pinpoint elusive production issues, my passion is the same: keep systems reliable, performant, and data-driven.More...
