I help teams run infrastructure they don't have to worry about. No surprise outages, no "hope this backup works" moments, no migration disasters. I've secured business-critical servers for financial institutions, built monitoring that surfaces issues early, and implemented backups with verified restores. My focus is long-term stability, not quick fixes, so problems stay solved instead of recurring. CLIENT TESTIMONIAL: "It has been nothing but a pleasure working with Temidara. We could not have been more happier than this..." - Keyway Solutions ⭐⭐⭐⭐⭐ PROBLEMS I SOLVE: - Server crashes at 2 AM with no monitoring in place - Backups that fail when you actually need them - Security vulnerabilities you don't know about - Infrastructure costs spiraling out of control - Cloud migrations that take down your business WHAT YOU GET: - Automated backup pipelines with scheduled restore verification (recovery proven, not assumed) - Monitoring that detects issues before customers notice - Reduced infrastructure costs by 40% through right-sizing and observability - Enterprise-grade security controls and identity management - Zero-downtime server migrations with continuous sync - Proactive incident response and security hardening CORE EXPERTISE: Cloud & Systems - AWS (EC2, S3, CloudFront, IAM) - GCP (Cloud Run, Compute Engine) - Linux (Ubuntu, RHEL, CentOS) - VPS management and optimization Security & Compliance - Microsoft SC-300 certified (Identity & Access Management) - Pentera Level 3 security validation - Zero Trust architecture implementation - Incident response and remediation - Enterprise security controls for financial services Infrastructure Automation - Docker, Ansible, Terraform, Bash/Python scripting - CI/CD pipelines - Infrastructure as Code (IaC) Monitoring & Observability - Prometheus, Grafana - Real-time alerting for CPU/memory/disk - Performance optimization and cost tracking Backup & Recovery - Automated backup pipelines - Scheduled restore testing - Disaster recovery planning MY APPROACH: Snapshot before changes → Test in staging → Automate recovery → Verify with monitoring. I document everything so future maintenance doesn't require my involvement. The goal is to leave systems documented, observable, and recoverable without ongoing dependence. WHY CLIENTS CHOOSE ME: - Microsoft Certified in Identity & Access Management (SC-300) - Pentera Level 3 Security Validation Engineer - Full-time Cyber Security Engineer - Financial services experience (compliance-ready) - I test my own backups - proven recovery, not assumptions - Documentation-first approach CURRENT ROLE: System Administrator at a major ISP, where I manage production infrastructure for enterprise clients. I respond to live incidents, implement enterprise-grade security controls and upgrades, and maintain 99.9% uptime for business-critical systems. This experience means I bring enterprise-level reliability and security practices to every freelance project, without the enterprise price tag. AVAILABILITY: Ready to start immediately. I usually start with a short technical assessment to reduce risk, confirm assumptions, and avoid rework before changes are made.
