Shell Script Development & Automation
$450.00 CADTransform repetitive manual processes into reliable automated workflows. We develop custom Bash and Python scripts for deployment pipelines, backup routines, log management, and system monitoring tasks.
Each script includes comprehensive error handling, detailed logging output, and clear documentation explaining logic flow and configuration options. Solutions are tested across multiple distributions to ensure portability.
Deliverables: Documented source code, usage examples, unit tests where applicable, and a maintenance guide for future modifications.
Linux Server Security Hardening
$850.00 CADStrengthen your server's defense posture through systematic security review and implementation of industry best practices. We audit SSH configurations, examine user privilege structures, analyze service exposure, and implement layered security controls.
Our approach includes configuring SELinux or AppArmor policies, establishing firewall rules that balance security with operational needs, implementing intrusion detection systems, and tuning kernel parameters for enhanced protection.
Deliverables: Security audit report, implemented hardening configurations, documented policy decisions, and ongoing security maintenance recommendations.
System Performance Optimization
$650.00 CADIdentify and resolve performance bottlenecks through systematic profiling and metric analysis. We examine disk I/O patterns, memory allocation efficiency, process scheduling behavior, and network throughput to pinpoint constraints limiting system capacity.
Optimization includes tuning I/O schedulers for your workload type, adjusting memory management parameters, configuring swap behavior, and optimizing process priorities. Changes are implemented incrementally with before-and-after benchmarking.
Deliverables: Performance analysis report, benchmark results, tuned configuration files, and monitoring setup to track ongoing performance metrics.
Network Configuration & Troubleshooting
$750.00 CADDesign and implement network topologies that support your infrastructure requirements. We configure routing tables, establish VLANs, set up network bonding for redundancy, and create firewall rule sets that permit necessary traffic while blocking unauthorized access.
Troubleshooting methodology uses tcpdump for packet capture analysis, netstat for connection state examination, and traceroute for routing path verification. We document network architecture decisions and maintain up-to-date topology diagrams.
Deliverables: Network architecture documentation, implemented configurations, troubleshooting procedures, and monitoring setup for network health metrics.
Backup & Disaster Recovery Solutions
$950.00 CADArchitect comprehensive backup strategies that protect critical data without overwhelming storage resources. We implement automated backup routines using rsync for incremental transfers, tar for archival, and snapshot technologies for point-in-time recovery.
Disaster recovery planning includes documenting system restoration procedures, testing recovery workflows to verify backup integrity, establishing recovery time objectives, and creating runbooks for emergency scenarios.
Deliverables: Backup system implementation, documented recovery procedures, tested restoration workflows, and scheduled verification routines to ensure backup reliability.
Monitoring & Alert Setup
$550.00 CADEstablish proactive monitoring systems that provide visibility into infrastructure health. We configure monitoring platforms like Nagios, Zabbix, or Prometheus to track system metrics, application performance, and service availability.
Alert configuration focuses on meaningful thresholds that catch genuine issues without generating false alarms. We define escalation procedures, integrate notification channels, and create dashboards that display system status at a glance.
Deliverables: Configured monitoring platform, customized alert rules, visual dashboards, and documentation of monitoring architecture and alert response procedures.
