Infrastructure
Linux, Windows Server, Proxmox VE, HA clusters, storage, backup, monitoring, networks and failure scenarios.
Technology should solve a business problem — not create another one.
eRNET combines server administration, Proxmox, high availability, backup, automation and business software engineering. Projects are led by Krzysztof Różycki from environment analysis through implementation and ongoing operations.
Automation
System integrations, scheduled jobs, workflows, notifications, imports, reporting and removal of repetitive manual work.
Software
Custom web applications, internal panels, reporting systems, roles, audit history, APIs and legacy migrations.
PRACTICE / NOT PRESENTATION
Experience comes from real environments and real constraints.
eRNET work covers Proxmox environments, Debian and Windows Server, Active Directory, backup and recovery, time-attendance systems, document automation, internal applications and integrations with existing databases and services. Projects are designed not only for features, but also for security, rollback, logging, monitoring and long-term maintainability.
ANALYSISDependencies and risk first.
ARCHITECTURETechnology selected for the problem.
TESTFailure and recovery are part of the design.
OPERATIONSThe system should still be understandable a year later.
